EP2331755B1 - Regulating device for a water outflow, in particular of sanitary fittings - Google Patents

Description

The invention relates to a regulating device for a water outlet in particular of sanitary fittings.

Sanitary fittings have, for example, faucets with water outlets or other means to remove water by a user. Such water outlets emit a jet of water whose intensity, ie the flow rate per time, is set by the user in a suitable manner according to his needs. In this case, the user can be guided by the water jet image that provides the water flowing out of the water outlet for him.

The increasing environmental awareness on the one hand and the rising costs of drinking water on the other hand have led to consumers becoming more and more interested in the question of water consumption. Every consumer and user is interested in not consuming more water than is necessary or reasonable for a particular application. At the same time, however, consumers and users also want the drinking water from the sanitary fitting to be reliably available in the required quantity and quality and to fulfill its task. The water jet picture should also be visually pleasant and regular.

Particularly important is the issue of water consumption where drinking water or service water is relatively expensive or is available only in limited quantities, such as on board ships or other means of transport. Even where relatively large amounts of drinking water are needed on a regular basis and thus lead to significant economic costs, this question plays a role, for example in the hotel sector or where often a large number of people wash their hands, for example in restaurants, swimming pools, hospitals and comparable facilities.

Thus, there is a considerable interest in the fact that the water provided to consumers and users that emerges from the water outlet can be used particularly effectively.

In the DE 35 10 107 C2 a shower and shower head is proposed for this purpose. He has a mouthpiece with a housing in which a spindle holder is inserted. In the spindle holder is a threaded hole with an adjusting screw screwed therein. In the adjusting spindle is a blind hole, are guided by the distribution channels to the outside. Water flows into the blind hole 1 in and out on the side distribution channels again. The distribution channels are more or less closed, depending on the depth of engagement of the adjusting spindle.

In this way, it becomes possible to set a certain maximum discharge amount by setting once. The integration of the adjustable elements inside the mouthpiece prevents users from damaging the adjustability or destroying the entire device through manual adjustment.

As a jet regulator such a mouthpiece is no longer usable as intended. For technical reasons, such a mouthpiece must be constructed with sleeves, which leads to a considerable length of 50 mm. Today's requirements such a conception no longer suffices.

Another possibility that is often desired with such mouthpieces is the ability to mix the effluent with air. Already in the CH-PS 315 823 Such a mouthpiece is proposed in which a part is inserted, which has a nozzle opening. Coaxial with the nozzle opening is a perforated and directed with the tip against the nozzle opening hollow cone. The space surrounding the hollow cone is connected to the outside air. As a result, air is sucked in from outside through the liquid jet emerging from the nozzle opening and divided by the hollow cone. This air is guided together with the liquid in the conical interior connected to the outlet of the mouthpiece. There arises a mixture of liquid and air. By the admixture of air in the jet of liquid, the total jet at the same time liquid consumption is several times greater than without the addition of air.

The disadvantage of such a concept is that the proportions are not changeable and considerable deposits can occur inside.

Nowadays, such strong aeration of the water jet of a water jet regulator is viewed critically in many applications. In water drains in sensitive areas, such as in or before operating rooms, in nursery wards, nursing homes and in all nursing homes is increasingly desired to avoid aerosol formation. Aerosol formation in and at the water outlets increases the risk of a Legionella infection. Conventional water jet regulators therefore have the problem that on the one hand an admixture of air in certain applications is desired, but on the other hand, in other applications, exactly this admixture of air should be avoided. These diametrically opposed desires in outlet fittings of sanitary facilities have not yet been fulfilled simultaneously. It must therefore be maintained for different applications, several variants of mouthpieces or shower heads or similar devices to satisfy all requirements can.

Even the dosage question for the water jet at outlet fittings is still being worked on and leads to different proposals.

For such purposes the EP 0 693 970 B1 a water jet regulator and flow limiter for sanitary fittings. The corresponding product is often successfully used in practice as an accessory for sanitary fittings. The flow rate of water outlets during use is optimally dosed. In this case, a water jet dividing device is provided in a housing which has a throttle plate and a cylinder hole plate, which form a distribution space between them. Through the cylinder hole plate already pre-choked water quantity is forwarded to the consumer, the cylinder hole plate means for Fine throttling of the amount of water contains. Downstream of the cylinder hole plate also a self-contained annular coil spring is arranged, which makes a fine distribution of the water flowing through and this can emerge as an orderly water jet from the user's point of view. The spray pattern is closed, but finely distributed.

The various dosing options and the finest distribution ensure that the consumer can not only satisfy the consumer with an optimized, reduced amount of water - not only emotionally but also effectively - the washing purpose. The various adjustment options give the installation, the possibility of adapting a roughly measured from the sanitary fitting and its dimensions water quantity on existing at the respective site conditions such as a washbasin and the local pressure conditions, so that the user by the operation of the sink fittings provided then be able to achieve an attunement precisely tailored to their current needs. The setting of the water jet regulator itself is usually not changed by the user.

These proven and used regulators work excellently on the usual water outlets of sanitary fittings. They each fit into a specific water outlet and are constructed so that they can be mounted in or on this water spout. However, in the course of recent years, for technical reasons, but more for the purpose of a more modern design, more and more new designs for the water outlets of valves have been introduced on the sanitary market. In the meantime, there are water outlets with very different diameters and also with different threaded holes, with which standard, not yet optimized water outlet elements can be installed in the water outlets.

The inner diameter of conventional water outlets is usually hitherto about 22 mm or 24 mm in diameter. With the increasing use of so-called designer fittings, other diameters are being created. The trend shows that the water outlets tend to be smaller and smaller Diameter, although also be quite realistic in the range of 14 mm or 16 mm diameter.

There are also water outlets, which have no internal threaded receptacle for water jet regulator, but have a different mounting option.

This means that the regulation devices according to the EP 0 693 970 B1 must be kept in stock in a variety of different embodiments in order to make an installation of these accessories in the respective different types of Wasserausläufen can.

This increases the costs and development costs, since a new regulating device has to be developed, realized and kept in stock for every newly launched water outlet and every new diameter of sanitary fittings.

It would be desirable if the expenses for this could be reduced.

It is therefore an object of the present invention to provide a proposal for a regulator for a water spout, in particular of sanitary fittings, with which the increasing costs for the ever new development of further embodiments can be counteracted.

The object is achieved by a regulating device for a water spout, in particular sanitary fittings, with a cylindrical sleeve having a central axis of the cylinder, which sleeve is designed for attachment to or in the water outlet, with a support plate arranged perpendicular to the axis of the sleeve, with a relative to the support plate about the axis rotatable and movable in the direction of the axis throttle and regulating element, through which water can flow from one side of the support plate to the other side of the support plate, wherein the throttling and regulating element comprises means for throttling the water, and with an annular distribution space for the water, which of the Support plate, the sleeve and the throttling and regulating element is limited to flow into the water from openings of the throttling and Regulierelements and out of the water, can flow out to a water outlet from the sleeve.

With such a concept, the costs for a regulating device for water outlets, which are to be used in different fittings on the sanitary market, can be significantly reduced. Namely, it is possible by the invention, the core area with the essential technical elements for each embodiment to keep identical and only a change of the sleeve used in each case together with attached thread for mounting in the water outlet with the preferably integrally formed with the sleeve support plate and optionally provide the further perforated plate.

These elements, which allow the installation at the water outlet and can look different, for example, for each diameter or for each internal thread of the water outlet, although taking from the perspective of the unbiased viewer and the sight of the entire regulator from the outside a substantial space, but are for the Cost of the entire regulator only of minor importance. This sleeve and possibly the perforated plate are readjusted and manufactured for each new on the market sanitary outlet, while the technical functionally more important and costly main components of the regulator according to the invention are always identical and therefore can be made in much larger series and numbers.

It is particularly preferred if a dosage of an additional amount of air in the water jet in the water outlet from the sleeve is adjustable by the movement of the throttle and regulating in the axial direction. In a preferred embodiment of the invention, moreover, it is also possible here to infinitely adjust a desired ventilation of the outgoing water jet.

This is achieved in particular by providing separate adjustment possibilities for the air supply and for the water supply in the axial direction.

It is particularly interesting if the device is provided for throttling the fine water below star-shaped transverse bores, and if in a throttling means of the device, the directly above the perforated plate mounted transverse bores are closed.

Thus, the above-mentioned problem can be taken into account that on the one hand there are applications in which an addition of air is very desirable, on the other hand, however, cases where such should be completely avoided. Finally, the degree of air admixture in different applications in different forms is interesting.

In all these applications, one and the same construction can now be used. It makes it possible to decide only at the place of use, if and how strong the addition of air should be and then determine this. For this now no longer have to be kept several alternatives or variants, it can simply be done a setting on the spot.

This further reduces stockpiling and even fewer series are needed.

The already mentioned perforated plate is made in one preferred embodiment in one piece with the throttling and regulating element. Namely, for a variety of embodiments, it is possible to provide a constant outer diameter of the orifice plate, although the water outlets have different configurations. It can nevertheless be worked by an alternative design of the wall thicknesses of the sleeve with an unchanged perforated plate by the inner diameter of the sleeve is kept constant at least in the area in which the perforated plate rests against the inside of the sleeve. It is then to adapt to different shapes and diameters of Wasserausläufen the wall thickness of the sleeve whose External thread or the corresponding length in the axial direction selected accordingly differently.

The sleeve compensates by a different wall thickness then the different inner diameter of the water outlet. The inner diameter of the sleeve is kept constant for all embodiments, while the wall thickness varies to the extent required for the respective water outlet.

Of course, this can lead to the sleeve having a very considerable wall thickness. However, this is not a problem since a relatively inexpensive material can be selected for the sleeve.

It can also give sleeves without an external thread, but with other possibilities and adjustments of the shape to the inner shape of the water spout. However, in each embodiment, the more expensive inner part of the entire device is identical.

Thus, it is possible to produce and store a large and thus economically producible quantity of the complexly constructed and technically sophisticated throttling and regulating element, it being possible to combine this type of throttling and regulating element with a multiplicity of different sleeves.

In this way, largely the most relevant in practice relevant water outlets can be supplied with one and the same throttle and regulating practical with the accessories of the invention. For extreme diameters, a separate form of the throttling and regulating elements to be prepared separately is then provided, which in turn can then reach a plurality of such water outlets with an extreme diameter, whereby at least a significant cost reduction takes place.

Also with these regulating devices according to the invention thus accessories for sanitary fittings are created as a flow restrictor, throttle device and as a stowage or guide body for the water jet serve. They make it possible to set and optimize the water flow rate.

In another embodiment of the invention, however, other requirements are taken into account. In hygienically sensitive areas, such as in the hospital or in the care sector, namely a ventilation of the water jet is not desired and waived. This also prevents bacterial contamination. Here, silver-plated surfaces can be used and, for example, a fine silver star with 99.8% silver content can be used.

As tests have already shown, the formation of clogged surfaces, so-called biofilms, is completely avoided in this case.

A preferred embodiment is particularly characterized in that at the adjacent end of the water outlet recesses are arranged in the form of a toothing that starting from the perforated plate symmetrical to the axis of a hollow cylinder extending in the direction of the water outlet, that between the hollow cylinder and the inner wall of the sleeve is provided a further recess that extend through the hollow cylinder radially extending bores, and that by the axis-parallel moving the perforated plate with the hollow cylinder, a way for an addition of air through the recesses of the teeth and the further recess through the holes in the flowing water is blocked or released.

With such an embodiment, it is possible to adjust accurately by a displacement of the throttle and regulating relative to the sleeve with the support plate, if and if so how much air to be added to the flowing water. The water can then penetrate with appropriate adjustment through the recesses or the teeth in the space between the inside of the sleeve and the hollow cylinder and enter through the holes in the hollow cylinder in the flowing water.

However, if the relative position of the throttle and regulating member is such that the path for the air through the recesses in the sleeve into the space between the inside of the sleeve and the hollow cylinder blocks, no air can occur.

This means that one and the same concept can be used both in hospitals where air admixture is not desired and in hotels where air admixture is in many cases extremely desirable. The corresponding setting can easily be made during the installation of the regulating device, as it corresponds to the respective place of use. It is no longer necessary to stock different regulatory devices for these two concepts.

The toothing of the recesses on the lower opening of the sleeve may additionally be formed as a tool fit and thereby be used beyond to intervene there with a tool and actuate the sleeve to disassemble them, for example, in the water outlet, for example screw. For this purpose, then a special tool can be used, which lead the fitters with it. Without such a special tool, an unauthorized person can not disassemble or misadjust the regulator.

An extension of the recesses, so the teeth on the inside of the sleeve in the direction of the support plate also has an additional advantage if a constant ventilation of the water jet is advantageous. Then the teeth can namely act by stabilizing the shape of the water jet.

In all embodiments, maintenance and cleaning work can be carried out quickly and easily. This is supported by the fact that all components are autoclavable. The maintenance cycles can be significantly extended by the very hygienic design of all embodiments.

The invention provides the possibility to increase individual advantages and comfort even with the most modern and new types of fitting outlets.

By the invention, a parallel and continuous regulation of the air or the addition of air to the equally infinitely adjusted amount of water is possible, and that of an addition of air from zero up to a maximum air admixing. All this can be done by a vertical adjustment of the throttle and Regulierelements, and particularly easy with hex keys, which engage in corresponding recesses.

Preferably, the regulation of the air, on the one hand, and of the water, on the other hand, takes place axially superposed with two different hexagonal wrenches, ie with two hexagonal wrenches of different diameters, each independently of one another. The separate and independent adjustment of the admixture of the air and the adjustment of the amount of water by means of two very simple Allen key from below has enormous advantages and has not been realized in any conception.

The various embodiments in the figures show an accessory for sanitary fittings. The accessory can be introduced into a water outlet of a sanitary fitting, not shown. It serves to regulate the water 10 flowing through this water outlet.

In the FIG. 1 In this case, a view is shown, which shows a water inlet opening 11 in the direction of the water 10. The water 10 thus flows perpendicular to the image plane in this water inlet opening 11 and is distributed there in different horizontal planes, which will be explained in more detail in connection with the other figures.

In the FIG. 2 is a section along the axis of the embodiment FIG. 1 shown, in which the water 10 flows from above into the water inlet opening 11.

A sleeve 20 has a cylindrical shape and can be mounted with its outside in or on a water outlet of a sanitary fitting. The sleeve 20 has a support plate 21, which is arranged perpendicular to the axis of the cylindrical sleeve 20 and preferably designed in one piece with the sleeve 20. The support plate 21 is provided in the middle with a through hole. The through hole has an internal thread 22.

In the bore with the internal thread 22 is a throttle and regulating element 30. This throttle and regulating element has an external thread 32 which cooperates with the internal thread 22 of the sleeve 20.

The throttling and regulating element 30 can be rotated in the support plate 21, wherein internal thread 22 of the sleeve 20 and external thread 32 of the throttle and Regulierelements 30 rotate relative to each other. In order to be able to effect this rotation, a hexagon socket 33 of the throttling and regulating element 30 can be seen at the lower end of the sectional view. In this hexagon socket 33 can be introduced by the fitter a corresponding hexagonal pin. When the throttling and regulating member 30 is rotated relative to the sleeve 20 in this form, the throttling and regulating member 30 moves vertically in the FIG. 2 up and down relative to the support plate 21 of the sleeve 20, which in connection with FIG. 4 will be explained.

The throttling and regulating element 30 in turn has a continuous central bore 31. To this central bore 31 leads in connection with FIG. 1 already mentioned water inlet opening 11th

Below the support plate 21, the throttling and regulating element 30 continues with an axisymmetric plate 36 which has star-shaped radially outwardly extending transverse bores 37.

Below this plate 36 is a perforated plate 40, which is provided with a plurality of axially parallel, but equidistant and adjacent to the circumference circular holes 41.

The diameter of the perforated plate 40 is so large that it extends with its outer circumference up to the inner wall of the sleeve 20 and closes with this movable, but largely tight. The perforated plate 40 is on the one hand rotatable relative to the sleeve 20, since the perforated plate 40 with the throttling and regulating member 30 as described above can be rotated together, on the other hand, it is due to the interaction of the internal thread 22 of the sleeve 20 with the external thread 32 of the throttle and Regulierelements 30 also mutually displaceable in the axial direction. The inner surface of the sleeve 20 and the outer surface of the perforated plate 40 together form an annular guide portion 42.

Underneath the perforated plate 40 with the circular bores 41, the throttling and regulating element 30 continues cylindrically, wherein the outer diameter corresponds approximately to that of the plate 36 with the star-shaped transverse bores 37.

This cylindrical region of the throttling and regulating element 30 thus passes below the perforated disk 40 with its circular bores 41 into a cylindrical shank 46.

The shaft 46 of the throttling and regulating element 30 extends axially approximately as far as the sleeve 20.

In the region in which the sleeve 20 and the throttling and regulating element 30 end downstream, a circumferential circular groove 47 is provided in the throttling and regulating element 30. In this circular groove, a spring 51 is arranged, in the form of a self-contained and around the entire circumference of the throttling and regulating 30 current spiral spring 51. As will be explained below, here the water 10 flows through the sprung spring 51, which forms a water outlet 14 from the arrangement according to the invention.

How to get in the FIG. 2 can recognize well formed between the support plate 21 of the sleeve 20 and the perforated plate 40 of the throttling and Regulierelements 30, a circumferential annulus or manifold space 12 which is bounded inwardly by the plate 36 and outwardly from the inner wall of the sleeve 20.

Below the perforated plate 40, a further annular space or storage space 13 is formed, which is bounded inwardly by the here continuous shaft 46 of the throttling and regulating element 30 and outwardly from the inner wall of the sleeve 20. In the axial direction, it is bounded above as mentioned by the perforated plate 40, downwardly from the coil spring 51 in the circular groove 47th

A regulating screw 60 can be screwed into the central bore 31 of the throttling and regulating element 30 counter to the inflow direction of the water 10. This adjusting screw 60 protrudes in this central bore 31 through the perforated plate 40 into the region of the plate 36 with the star-shaped transverse bores 37.

The adjusting screw 60 has a hexagon socket 63. The hexagon socket 63 serves to be able to move the adjusting screw 60 upwards or downwards in the central bore 31 of the throttling and regulating element 30 by turning the regulating screw 60. As a result, a fine adjustment of the exact position of the adjusting screw 60 is possible. This stands out with their in the representation in the FIG. 2 It can therefore be precisely adjusted by fine adjustment with which speed or intensity in the central bore 31 downwardly flowing water 10 is deflected at right angles in the star-shaped transverse bores 37 to to get to the distributor room 12.

Considering now the course of the water 10 through the entire assembly, this first flows through the water inlet opening 11 into the central bore 31 of the throttling and regulating element 30 and there to the plate 36 with the star-shaped transverse bores 37. The further flow through the central bore 31st is stopped here by the screwed in from the opposite side adjusting screw 60. The flow of the water 10 thus continues through the star-shaped transverse bores 37 into the distributor chamber 12. There, the water 10 is again deflected by a right angle and flows axially parallel through the circular holes 41 of the perforated plate 40 in the storage space 13 and from there by the coil spring 51 parallel to the wall of the sleeve 20 from the arrangement at the water outlet 14 out. By the coil spring 51 is a fine distribution of the water as effluent, ordered water jet.

Integral with the throttling and regulating element 30, the plate 36, the perforated plate 40 and the cylindrical shaft 46 are thus formed with the circular groove 47 in this embodiment. The coil spring 51 serves as a stowage and guide body for the exiting water jet.

In the FIG. 3 one sees the embodiment of the FIG. 1 seen from below. Accordingly, one looks outside on the circumferential cylindrical wall of the sleeve 20th

This is followed inwardly by the coil spring 51 and further inwardly of the cylindrical shank 46 of the throttling and regulating element 30.

Inside the cylindrical shaft 46 of the throttling and regulating element 30, the hexagon socket 33 is arranged. In this hexagon socket can be intervened in the installation to rotate the entire throttle and regulating member 30 relative to the support plate 21 of the sleeve 20. Due to the internal thread 22 in the support plate 21 by this rotation, the entire throttle and regulating element 30 as shown by the arrows 90 in the FIGS. 2 and 4 indicated shifted in the axial direction.

Inside the hexagon socket 33 in the FIG. 3 you see the adjusting screw 60th This is - how to FIG. 2 can be removed - laid deeper inward. Within the scope of the regulating screw 60 can be seen the hexagon socket 63, in which can be intervened from this side with an even smaller hexagon by the installer to turn the adjusting screw 60 relative to the throttling and regulating member 30.

In the presentation in the FIG. 4 it can be seen how a rotation of the throttling and regulating element 30 relative to the sleeve 20 has an effect. The entire throttling and regulating element 30 with the perforated plate 40 has moved downwards in the direction of the arrows 90. As a result, the distribution chamber 12 has become significantly larger, comparing the representation in the FIG. 4 with the representation in the FIG. 2 ,

Not shown is a shift along another indicated arrow 91, which indicates the adjustment of the adjusting screw 60 within the throttle and regulating element 30. It can be seen that a tip 64 can slide into the plate 36 and thus change the Stormungsverhältnisse in the transverse bores 37 in the plate.

When comparing the FIGS. 2 and 4 it can also be seen that the top of the plate 36 forms a kind of flange 38 which can be moved up to the bottom 24 of the support plate 21 in the direction of arrows 90. The flange 38 forms with the bottom 24 of the support plate 21 a stop. While in the FIG. 2 the flange 38 almost abuts the stop 24, it is in the FIG. 4 arranged at a significantly greater distance.

In addition to the coarse adjustment, by the rotation of the throttle and regulating element 30 between the positions in the FIGS. 2 and 4 can be achieved, the rotation of the adjusting screw 60 along the arrows 91 allows a fine adjustment, the amount of water 10 is infinitely adjustable between a minimum and a maximum.

As one particularly in the representation in the FIG. 4 In addition, a downward movement of the throttling and regulating element makes it possible, in the region between the inner wall of the sleeve 20 and the coil spring 51 or through its edge regions, to suck amounts of air into the water jet and to be discharged therewith. This allows an optimization of the water jet image.

In the FIGS. 2 and 4 In addition, the top 25 of the support plate 21 and a sealing surface 23 on the inside of the sleeve 20 in the area above the support plate 21 are still indicated. These surfaces can be used for mounting in the water outlet.

In the FIG. 5 is a similar view FIG. 1 illustrated, however, to another, second embodiment of the invention. It can again be seen that this embodiment also has a water inlet 11, which initially allows the water 10 to flow perpendicular to the image plane. In located behind the image level further levels then takes place again a multiple deflection of the flow direction of the water 10, wherein first transverse holes 37 flow the water outward and then circular holes 41 in the perforated plate 40, the water again parallel to the axis.

In the FIG. 6 is now shown in greater detail the second embodiment of the invention.

You can see the sleeve 20 with the support plate 21 here only dashed. The internal thread 22 in the support plate 21 in turn interacts with the external thread 32 the throttling and regulating element 30 together. Upon relative rotation of the throttling and regulating element 30 in the sleeve 20, the throttling and regulating element 30 again moves up and down in the direction of the arrows 90. This movement upwards and downwards is in turn limited by the flange 38 on the upper side of the plate 36 with the transverse bores 37 and the stop 24 on the underside of the support plate 21.

It is indicated in this embodiment that the sleeve 20 is equipped with an external thread 26 to be screwed into a water outlet (not shown), for example a sanitary fitting.

As in the first embodiment, the plate 36 with the transverse bores 37 is located on the throttling and regulating element 30 and subsequently the perforated plate 40 is provided with the axially parallel and circular circular bores 41 arranged around the axis, which in turn engage with the guide region 42 on the inner wall of the Sleeve 20 is guided.

Below the perforated plate 40, the throttling and regulating element continues as a cylindrical shank 46.

Again, the adjusting screw 60 is provided with its hexagon socket 63, with which also in this embodiment, a fine adjustment can be adjusted continuously from the maximum to the minimum of the amount of water 10.

The adjustment of the throttling and regulating element 30 is effected by the hexagon socket 33 at the lower end of the cylindrical shaft 46. For this embodiment, only one position is shown in the drawings. In this version, the flange 38 is not on the stop 24, so that the distribution chamber 12 is slightly larger.

With the possibility of adjustment in the direction of arrow 90 of the cylindrical shaft 46, the water jet image can be optimized.

The water 10 enters via the water inlet 11 in the central bore 31 in the throttling and regulating member 30, passes through the support plate 21 into the Plate 36 and exits in this through the star-shaped transverse holes 37 in the distribution chamber 12. From there it passes through the circularly arranged circular holes 41 in the perforated plate 40 again axially parallel in the storage space 13 to the water outlet 14th

Unlike in the embodiment of FIGS. 1 to 4 Here, no coil spring 51 is provided, but instead a star 52, which forms the water outlet 14 here. The star 52 is part of a Stemstrahlreglers and is arranged at a step 48 of the cylindrical shaft 46.

The FIG. 7 again shows a view of the embodiment of the FIGS. 5 and 6 in this case, from below, so that you can see from the inside outward first hexagon socket 63 of the adjusting screw 60, then the hexagon socket 33 in the cylindrical shaft 46 and then further outward the star beam controller 52 can see. On the outside, a view of the lower edge of the sleeve 20 results annularly again.

In the FIG. 8 again you see a representation similar to the FIGS. 1 and 5 , this time as a top view of a third, in the FIGS. 8 to 11 illustrated embodiment of the invention.

It can be seen a sleeve 20 and looks at the top 25 of the support plate 21. In the middle of the inlet opening 11 can be seen.

FIG. 9 shows a section similar to the FIGS. 1 and 6 , Again, you can see a sleeve 20 with a support plate 21 and an external thread 26 (see FIG. 11 ) for mounting in the water outlet of a sanitary fitting.

On the upper side 25 of the support plate 20 are still dashed sealing elements 27 indicated, which may be constructed here in the form of an O-ring. These sealing elements are not shown in the other embodiments, but may also be present there.

In the support plate 21 is provided with a thread 32, the throttle and regulating element 30 with its central bore 31, which in turn a rotation in the direction of the arrows 90 can be moved up and down.

The throttling and regulating element 30 in turn integrally formed has a plate 36 with transverse bores 37 and below a perforated plate 40 with axially parallel circular bores 41. Below the perforated plate 40, the throttling and regulating element 30 passes in a cylindrical shank 46.

Unlike the embodiments of FIGS. 1 to 7 Here is also provided by the perforated plate 40 on starting a hollow cylinder 43.

In a presentation of the FIG. 9 the throttle and regulating member 30 is screwed by means of hexagon socket 33 all the way up and is characterized by the flange 38 of the plate with the transverse bores 36 on the stop 24 on the underside of the support plate 21 at.

Also provided is again the adjusting screw 60 with its hexagon socket 63, which can be pushed by rotation in the central bore 31 upwards and thus along the arrows 91 can be moved up and down.

Unlike the embodiments in the FIGS. 1 to 7 This embodiment is particularly advantageous for the case that an admixture of air for hygienic reasons, for example, should be completely excluded.

For this purpose, the hollow cylinder 43 is provided on the perforated plate 40 with grooves 71, 72 in which O-rings 73, 74 are located. In addition, a recess 75 is provided for the air intake.

Further, here is a locking ring 53 is arranged for the star beam controller 52. This can be a snap ring.

At the lower end of the sleeve 20 can be seen a toothing 38. This is rotating at this cylindrical lower end of the sleeve 20 alternately formed as a tooth and as a blank, as in the FIG. 10 can recognize very well.

In the presentation in the FIG. 9 However, above the teeth 28 is still a seal of the inner wall of the sleeve 20 relative to the outside of the hollow cylinder 43 in the form of the O-ring 73 in the groove 71. The gearing 28 is so far in the position of the arrangement according to the FIG. 9 still out of action. However, the toothing 28 can also serve as an engagement for a mounting tool in order to mount the sleeve 20 and thus the system according to the invention in the water outlet of a sanitary fitting.

The water 10 also enters in this embodiment via the water inlet 11 in the central bore 31 of the throttling and regulating element 30 a. It in turn reaches into the region of the plate 36 and enters there via the transverse bores 37 in a distribution chamber 12 a. This distribution chamber 12 acts here as a pressure chamber. He steps out of the pressure chamber of the distributor chamber 12 through the circularly arranged holes 41 in the perforated plate 40 in the storage space 13, which is constructed as a mixing chamber. From the storage space 13, the water then exits through the star 52 as a water outlet 14.

In the FIG. 10 is a view of the sleeve 20 and the other elements of the embodiment in the FIGS. 8 and 9 shown from below.

It can be seen again inside the hexagon socket 63 of the regulating screw 60 and arranged around the hexagon socket 33 of the throttling and regulating member 30 with its cylindrical shank 46th

Arranged thereupon, one sees the star jet regulator 52, from which the water here flows as water outlet 14 in the direction of the viewer. This area is again annularly surrounded by the lower edge of the hollow cylinder 43, which extends from the perforated plate 40 to the viewer. Also, this element is integrally connected in the illustrated embodiment with the throttle and regulating member 30.

To this annular element, the toothing 28 can be seen, that is, a partial gradation of the inner lower edge of the sleeve 20, whose wider area one recognizes in the next ring.

In the FIG. 11 one sees the embodiment of the FIGS. 8 to 10 , this time again in a position in which the throttle and regulating element 30 has moved downwards with its further elements, that is, similar to the illustration in FIGS FIGS. 4 and 7 ,

So you see again the sleeve 20 with its external thread 26 for mounting on a water outlet of a sanitary fitting. To recognize is again turn at the lower end of the sleeve 20, the teeth 28th

In the sleeve 20 is the throttling and regulating member 30 with the plate 36 with the star-shaped transverse bores 37 and the perforated plate 40. From the perforated plate 40 extends axially parallel to the hollow cylinder 43 with the grooves 71 and 72 and the O-rings 73 arranged therein and 74. Between the two grooves 71 and 72 is again the recess 75 for an even closer to be explained in this position air intake.

It can also be seen again the star beam controller 52 with its retaining ring 53rd

Again, the adjusting screw 60 can be seen with its hexagon socket 63.

The throttle and regulating member 30 is not rotated in this position with the flange 38 of the plate 36 to the stop 24 on the underside of the support plate 21.

As a result, now the lower end of the hollow cylinder 43 with the groove 71 and the therein O-ring 73 (see FIG. 9 ) no longer seals around relative to the inner wall of the sleeve 20, but in the region of the toothing 28 abuts.

In the illustrated cutting position, it can therefore be seen that through the interdental space, so by the existing gap between two teeth of the teeth 28 air from outside the sleeve 20 in the recess 75 between the two grooves 71 and 72 in the outer wall of the hollow cylinder 43rd can get. This air admixture 76 may be in the position of FIG. 9 not take place.

In the hollow cylinder 43 are radially extending holes 44, which also already in the illustration of FIG. 9 are present, but have no function there. The admixing of air 76 can thus now enter through the tooth gap of the toothing 28, the recess 75 in the outer wall of the hollow cylinder 43 and through the radially extending holes 44 in the hollow cylinder in the hollow cylinder and there in the stowage compartment 13, the here as above in connection with of the FIG. 9 already mentioned forms a mixing chamber, namely for the mixture of this air admixture 76 with the entering through the circular holes 41 from the perforated plate 40 water 10th

In this position, therefore, as a whole, the water 10 enters via the water inlet 11 in the central bore 31 in the throttling and regulating member 30 and flows through this in the representation down to the plate 36, in which it is stopped by the screwed from below adjusting screw 60 and flows through the star-shaped transverse bores 37 radially outward into the distributor chamber 12, which forms the pressure chamber here. From the distribution chamber 12, the water 10 then flows through the axis-parallel circular holes 41 in the perforated plate 40 in the storage space 13, which forms a mixing chamber here, in which the water is mixed with the inflowing through the radial bores 44 air admixture 76. The water / air mixture then exits through the star jet regulator 52 as a water outlet 14.

In this embodiment, it is now possible, on the one hand by adjusting the adjusting screw 60 in the direction of arrow 91 to adjust the amount of water from a maximum to a minimum infinitely fine and on the other hand by rotation and thus adjustment of the throttle and regulating member 30 relative to the sleeve 20th in the direction of arrows 90 a stepless adjustment and reduction of the air admixing 76 relative to the flowing amount of the water 10 to achieve.

In this embodiment, therefore, can be decided by the installer by the rotation of the throttling and regulating element 30 by means of the hexagon socket 33, whether or not an air admixture 76 should take place at all, and at the same time how strong this air admixture should be.

This has in particular the effect that this embodiment can be used both if, for hygienic or legal requirements, an admixture of air must not take place, for example in the hospital area, as well as when this is currently desired, for example in hotel and catering establishments.

It is therefore no longer necessary to design and store different embodiments for these completely different and mutually exclusive uses. One and the same embodiment can be used for both purposes, and an adaptation to the respective desired application can be made simply by appropriate adjustment of the throttling and regulating elements 30.

It can be ensured by the teeth 28 and a specially adapted for these teeth 28 tool that no abuse and no confusion can take place by unauthorized person.

In FIG. 12 a fourth embodiment of the invention is shown. It can be seen again from an axial end of an arrangement according to the invention in the flow direction of the water 10 to the water inlet 11. The water inlet 11 leads into the central bore 31 of the throttling and Regulierelements 30, of which one can see here the upper edge and in this on the plate 36 with the transverse bores 37 can see.

In the FIG. 13 is similar to the representation of the FIG. 6 a section along the axis of the inventive arrangement shown. The sleeve 20 with her External thread 26 and the support plate 21 can be seen in dashed lines. You can also see the bottom 24 and the top 25 of the support plate 21st

By the support plate 21, the throttling and regulating member 30 projects with the axially extending central bore 31 and the external thread 32nd

Below the support plate 21, the throttle and regulating element 30 extends first to the plate 36 with the transverse bores 37 and then instead of a perforated plate directly into a cylindrical shaft 46 with a circular groove 47 for receiving a coil spring 51st

The cylindrical shaft is in turn provided below with a hexagon socket 33 to be rotated relative to the support plate 21 about the axis can.

In the central bore 31 in turn protrudes from below a regulating screw 60, which can be rotated relative to the cylindrical shaft 46 by engaging in a hexagon socket 63. As a result of this rotation, the adjusting screw 60 is movable upwards and downwards in the direction of the arrows 91 and thus projects more or less deeply into the plate 36 with the transverse bores 37.

Shown again is a position in which the flange 38 bears against the top of the plate 36 directly on the bottom 24 of the support plate 21 as a stop.

The water 10 enters the water inlet 11 and from there into the central bore 31 in the throttling and regulating element 30 a. It flows down to the top of the regulating screw 60 and is thus redirected at right angles into the transverse bores 37. It then flows between the outer wall of the cylindrical shaft 46 and the inner wall of the sleeve 20 down through the coil spring 51 through the water outlet 14th

This version made possible by the corresponding rotation of the throttling and regulating element 30 by means of the hexagon socket 33 in the illustration in the FIG. 13 counterclockwise thread 32 optimization of the water jet image. An adjustment of the amount of water from Maxiumum to Minimum can be done continuously by adjusting the adjusting screw 60. In this embodiment, considerable amounts of air can be sucked into the flowing water.

The FIG. 14 again shows a view of the embodiment of the FIGS. 12 and 13 in this case, from below, so that you can see from the inside outwards first the hexagon socket 63 of the adjusting screw 60, then the hexagon socket 33 in the cylindrical shaft 46 and then further outwardly the coil spring 51 in its annular state around the cylindrical shaft 46. On the outside, a view of the lower edge of the sleeve 20 can be seen in broken lines in this case.

FIG. 15 shows a fifth embodiment of the invention. The water then flows perpendicular to the image plane through the upper portion of the throttling and regulating element with the external thread 32 and is then redirected radially outward in transverse bores 37 behind the plane of the page ,

You see in the FIG. 15 In addition, that then an extension of the throttling and regulating element 30 moves into view.

In the FIG. 16 is in a section along the axis, the fifth embodiment of the invention can be seen better. The sleeve 20 with its external thread 26 and the support plate 21 is as in the FIG. 13 to recognize in dashed lines. You can also see the bottom 24 and the top 25 of the support plate 21st

By the support plate 21, the throttling and regulating member 30 projects with the axially extending central bore 31 and the external thread 32nd

Below the support plate 21, the throttling and regulating element 30 extends first to the plate with the transverse bores 36th

Below the plate 36 with the transverse bores 37 is in the embodiment in the FIG. 16 as well as in the embodiment of FIG. 13 no perforated plate intended. In this embodiment, however, the throttling and regulating member extends almost entirely to the inner wall of the sleeve 20 to re-taper in a downward direction parallel to the axis. Overall, this area of the throttling and regulating element 30 in this case does not assume a cylindrical shank-like shape, but rather forms a kind of hemisphere 49 with rounded shapes.

This hemisphere 49 is again provided below with a hexagon socket 33 to be rotated about the axis relative to the support plate 21 can.

In the central bore 31 projects from below a regulating screw 60, which can be rotated by means of engagement in a hexagon socket 63 relative to the hemisphere 49. As a result of this rotation, the adjusting screw 60 is movable upwards and downwards in the direction of the arrows 91 and thus projects more or less deeply into the plate 36 with the transverse bores 37.

Shown again is a position in which the flange 38 bears against the top of the plate 36 directly on the bottom 24 of the support plate 21 as a stop.

The water 10 enters the water inlet 11 and from there into the central bore 31 in the throttling and regulating element 30 a. It flows down to the top of the regulating screw 60 and is thus redirected at right angles into the transverse bores 37. It then flows downwards through the water outlet 14 between the outer wall of the hollow ball 49 and the inner wall of the sleeve 20.

In this fifth embodiment, a water jet without air admixture is formed at the water outlet 14. The shape of the element 49 together with the surrounding sleeve 20 causes the water 10 flowing between the hollow ball 49 and the inner wall of the sleeve 20 to be concentrated towards the axis, in particular also with regard to the lack of added air. It creates a particularly quiet beam, which is particularly desirable for example in the removal of drinking water or filling of vessels. Such a beam is particularly good for the user, especially regarding the filling speed of vessels or similar purposes.

In the FIG. 17 this embodiment is shown from below. From outside to inside, the sleeve 20, therein the hemisphere 49 of the throttling and regulating element 30, further inwardly then the hexagon socket 33 in the hemisphere 49 and even further inside the hexagon socket 63 in the adjusting screw 60th

By adjusting the regulating screw 60, an adjustment of the amount of water from a maximum to a minimum can be continuously made. By rotating the throttling and regulating member 30 by engaging the hexagon socket 33 counterclockwise, the water jet pattern can be optimized.

In the FIG. 18 is shown on average the outlet of a valve. From in the FIG. 18 Right side, the water would be supplied. It can be seen in this illustration, an embodiment of a regulating device according to the invention for a water outlet, which is inserted into the illustrated area, that by rotation of the throttling and regulating member 30 is a movement upwards and downwards and thus an influencing of the flowing water is possible.

In the FIG. 19 one looks at the embodiment of the FIG. 18 from below. It can be seen on the surface of the outlet region of a valve and from below the assembled sleeve 20 and therein the throttling and regulating element 30th

For the viewer in front of the throttle and regulating element is a ring insert 81, which in the FIG. 22 will be discussed in more detail.

In the FIG. 20 is a view of this ring insert 81 to recognize from the side.

In the FIG. 21 For clarity, the embodiment is FIG. 19 shown omitting the ring insert 81.

In the FIG. 22 a separate representation of the ring insert 81 is shown. The ring insert 81 consists of a plurality of cylindrical rings 82, which are interconnected by webs 83.

In the interior, the webs 83 project beyond the innermost ring 82 in the direction of the center. As a result, a secure attachment can be ensured by the ring insert 81, which acts as a kind of locking ring.

The rings 82 and optionally also the webs 83 are preferably made of a ceramic material, for example of polymers, or of pure silver. Such ring inserts 81 will be used above all in hygienically sensitive areas, for example in operating theaters, intensive care wards or nursing stations.

In the FIG. 23 a sleeve 20 in the form of an adapter sleeve is shown in section. This sleeve has an inner hexagon 85. The sleeve 20 can, with the aid of the hexagon 85 by means of a hexagonal wrench, that is, a so-called Allen key, in fitting outlet about in embodiments of the FIGS. 18, 19 and 21 be assembled or disassembled.

This form of a sleeve 20 thus serves as an adapter for valves in which a regulation device according to the invention is to be retrofitted, so if, for example, subsequently a Reguliermöglichkeit for both the air content and the water content to be retrofitted. The advantage of this embodiment is, inter alia, that no crown-shaped toothing as in some of the preceding embodiments is needed. This means that there is less surface area that could still serve as the basis for microbial contamination.

In addition, a chamfer 86 and / or a toothing 87 can be provided in the opening region.

In the center of the sleeve 20 is a bore with the internal thread 22. In this internal thread 22 may in the FIG. 23 Not yet reproduced throttle and regulating element 30 are screwed.

For sealing and fixing in the outlet area of the valve from the FIGS. 18, 19 and 21 For example, an O-ring 73 and an external thread 26 are provided.

In the FIG. 24 is an illustration of the sleeve 20 from the FIG. 23 , seen from below. One sees on the hexagon socket 85 and the bore with the internal thread 22.

Evident is also the teeth 87th

In the FIG. 25 is now shown as in a sleeve 20 approximately from the FIGS. 23 and 24 a throttle and regulating element 30 is inserted.

You can still see the hexagon socket 85 and it can be seen that the bevel 86 and the teeth 87 can be used for a particularly precise and accurate regulation of the air content. Reference is made to the description of the embodiment in the FIGS. 9, 10 and 11 referenced, whose functionality is similar in this respect.

In the FIG. 26 an embodiment of a sleeve 20 is shown, the embodiment of the FIG. 23 similar. Here, no hexagon socket 85 is provided for screwing into the outlet of a fitting, but instead a slot 88 in the lower peripheral edge of the sleeve 20. It can be seen again the external thread 26 with the O-ring 73 and the internal thread 22 of the bore for the passage of the throttle and regulating element 30 from the FIG. 25 ,

The chamfer 86 can be seen here on both sides.

In the FIG. 27 is a view of the embodiment of the FIG. 26 to be seen from below. Here you can see especially well the slit 88 for receiving a screwdriver blade.

Also, the chamfer 86 can be seen in their all-round configuration.
