Description

KARTUSCHE FÜR EIN EINHEBELMISCHVENTIL CARTRIDGE FOR A SINGLE LEVER MIXING VALVE
Die Erfindung betrifft eine Kartusche für ein Einhebelmischventil mit einer festen und einer beweglichen Dichtscheibe, die in einem Gehäuse angeordnet sind, wobei die bewegliche Dichtscheibe eine Ausnehmung für den Eingriff eines Steuerzapfens eines einen Pivothalter durchsetzen- den Steuerhebels aufweist.The invention relates to a cartridge for a single-lever mixer valve with a fixed and a movable sealing disk which are arranged in a housing, the movable sealing disk having a recess for the engagement of a control pin of a control lever which penetrates a pivot holder.
Bei herkömmlichen Einhebelmischventilen wird die Durchflußmenge des Ventils durch ein Anheben oder Absenken eines Griffhebeis, der mit dem Steuerhebel fest verbunden ist, bestimmt, wohingegen die Temperatur durch ein Verschwenken nach links oder rechts zu bestimmen ist. Entsprechend bewirkt das Anheben oder Absenken des Griffhebeis, daß der mit dem Griffhebel fest verbundene Steuerzapfen die bewegliche Dichtscheibe in der Kartusche ge- genüber der festen Dichtscheibe verschiebt. Ist das Ventil verschlossen, so ist der Griffhebel ganz abgesenkt. Beim Anheben des Griffhebels gelangt durch die Verschiebung der beweglichen Dichtscheibe die in der beweglichen Dichtscheibe vorhandene Mischkammer über den Kalt- und/oder armwasserdurchtritt sowie den Mischwasserdurch- tritt in der festen Scheibe, so daß es zum Austritt von Mischwasser kommen kann. Ist das Einhebelmischventil in herkömmlicher Weise symmetrisch ausgebildet, so bewirkt das gänzliche Anheben des Griffhebels einen maximalen Durchtritt von Mischwasser durch das Ventil . Ist es nun für den Benutzer des Einhebelmischventils unerheblich, welche Temperatur das austretende Wasser hat, so wird er den Griffhebel in der mittleren Position anheben, und zwar bis zum Anschlag, selbst wenn er nicht eine derartig große Durchflußmenge benötigt. Und zwar vor allem deswegen, weil der Bedienungsweg für den Griffhebel relativ kurz ist, so daß der Benutzer nicht an eine Dosierung der Wassermenge denkt. Dabei wird aber natürlich eine größere Menge an Wasser und auch Energie - da es sich um Mischwasser handelt - verschwendet als tatsächlich notwendig wäre.In conventional single-lever mixer valves, the flow rate of the valve is determined by raising or lowering a handle that is firmly connected to the control lever, whereas the temperature is determined by pivoting to the left or right. Accordingly, the raising or lowering of the handle lift causes the control pin, which is firmly connected to the handle lever, to move the movable sealing disk in the cartridge relative to the fixed sealing disk. If the valve is closed, the handle lever is completely lowered. When the handle lever is raised, the displacement of the movable sealing washer causes the mixing chamber in the movable sealing washer to pass through the cold and / or arm water passage and the mixed water passage in the fixed washer, so that mixed water can escape. If the single-lever mixer valve is of symmetrical design in a conventional manner, the complete lifting of the handle lever causes maximum passage of mixed water through the valve. If it is irrelevant for the user of the single-lever mixer valve what temperature the escaping water has, he will raise the handle lever in the middle position, to the stop, even if he does not need such a large flow rate. This is mainly because the operating path for the handle lever is relatively short, so that the user does not think about metering the amount of water. Of course, a larger amount of water and energy - since it is mixed water - is wasted than would actually be necessary.
Es gibt bereits Kartuschen, in die ein zusätzlicher Bauteil eingesetzt ist um ein unbeabsichtes, vollständiges Öffnen des Ventils zu verhindern. Dieser Bauteil kann ein federndes Element enthalten, welches durch Aufbringen von Druck ein vollständiges Öffnen des Ventils ermöglicht. Die Herstellung des Bauteils und die Montage in der Kartusche ist jedoch zeit- und kostenaufwendig.There are already cartridges in which an additional component is inserted to prevent the valve from being opened accidentally. This component can contain a resilient element, which enables the valve to be opened completely by applying pressure. However, the production of the component and the assembly in the cartridge is time-consuming and costly.
Aufgabe der vorliegenden Erfindung ist es, ohne zusätzlichen Zeit- und Kostenaufwand ein Einhebelmischventil der eingangs genannten Art zu schaffen, das nur dann die maximale Durchflußmenge freigibt, wenn dies bewußt vom Be- nutzer eingestellt wird. D.h., für das öffnen des Ventils ohne Rücksicht auf Temperatur und Durchflußmenge soll eine geringere Durchflußmenge als bisher gegeben sein und dennoch soll der Komfort einer großen Durchflußmenge möglich sein.The object of the present invention is to create a single-lever mixer valve of the type mentioned at the outset, which only releases the maximum flow rate if this is deliberately set by the user, without additional time and cost. That is, for opening the valve regardless of temperature and flow rate, there should be a lower flow rate than before and yet the convenience of a large flow rate should be possible.
Diese Aufgabe wird dadurch gelöst, daß die bewegliche Dichtscheibe auf ihrer dem Steuerzapfen zugewandten Oberfläche im Bereich ihres äußeren Umfanges eine Stufe als überfahrbaren Volumensanschlag gegenüber dem Pivothalter aufweist. Wird nunmehr der Griffhebel angehoben, so überträgt sich diese Schwenkbewegung auf den Steuerzapfen und dieser verschiebt die bewegliche Dichtscheibe gegenüber der festen Dichtscheibe. Dabei nähert sich die erfindungsgemäße Stufe dem Rand des Pivothalters, bis sie schließlich an denselben anschlägt. Die Höhe der Stufe ist nunmehr so gewählt, daß bei einem größeren Druck auf den Griffhebel, d.h. bei Erhöhung des Öffnungsmomentes am Griffhebel, das Scheibenpaket aus fester und beweglicher Dichtscheibe ge- gen den Anpreßdruck der Dichtungen bei den Wassereingängen und beim Wasserausgang und gegen den Wasserdruck nach unten bewegt wird, und somit die Stufe überfahren werden kann bis zur maximalen Durchflußmenge. Bei der herkömmlichen Bedienung ohne besonderen Bedacht auf Temperatur und Wassermenge wird die bedienende Person ein Anheben des Griffhebels und damit ein Verschieben der beweglichen Dichtscheibe nur bis zum Anschlag des Pivothalters an der Stufe auf der Dichtscheibe ausführen. Will er bewußt mehr Wasser entnehmen, so kann er durch ein kräftiges Anheben des Griff ebeis dies bewußt hervorrufen.This object is achieved in that the movable sealing disk has on its surface facing the control pin in the area of its outer circumference a step as a traversable volume stop with respect to the pivot holder. If the handle lever is now raised, this swiveling movement is transferred to the control pin and this moves the movable sealing disk relative to the fixed sealing disk. The step according to the invention approaches the edge of the pivot holder until it finally strikes the same. The height of the step is now selected so that when there is greater pressure on the handle lever, ie when the opening torque on the handle lever is increased, the disk package consisting of a fixed and movable sealing disk against the contact pressure of the seals at the water inlets and at the water outlet and against the water pressure is moved down, and thus the stage can be crossed up to the maximum flow rate. In conventional operation without special attention to temperature and water volume, the operator will only lift the handle and thus move the movable sealing washer until the pivot holder stops on the step on the sealing washer. If he deliberately wants to take out more water, he can consciously cause this by lifting the handle firmly.
Es ist bekannt, zwischen der beweglichen Dichtscheibe und dem Pivothalter einen sogenannten Dichtscheibenträger vorzusehen. Ein solcher Dichtscheibenträger dient als Gleitlager bei der Bewegung der beweglichen Dichtscheibe gegenüber dem Pivothalter und bei der Bewegung des Steuerzapfens in der Ausnehmung der beweglichen Dichtscheibe. Der Dichtscheibenträger ist durch das Eingreifen in die Ausnehmung der Dichtscheibe gegenüber der Dichtscheibe nicht beweglich. Erfindungsgemäß ist die Stufe in einem solchen Dichtscheibenträger vorgesehen, der auf der dem Steuerzapfen zugewandten Oberfläche der beweglichen Dichtscheibe angeordnet ist und der in die Ausnehmung in der Dichtscheibe für den Steuerzapfen eingreift. Somit kann eine herkömmliche Dichtseheibe verwendet werden und dennoch wird kein zusätzlicher Bauteil benötigt. Vorzugsweise sind eine oder beide der aufeinandertreffenden Kanten der Stufe und des Pivothalters abgeschrägt oder abgerundet. Somit ist ein deutlicher Widerstand beim Überwinden der Stufe zu fühlen, es kann jedoch zu keinem Verkanten kommen.It is known to provide a so-called sealing washer carrier between the movable sealing washer and the pivot holder. Such a sealing disk carrier serves as a sliding bearing when the movable sealing disk moves relative to the pivot holder and when the control pin moves in the recess of the movable sealing disk. By engaging in the recess of the sealing washer, the sealing washer carrier is not movable relative to the sealing washer. According to the invention, the step is provided in such a sealing disk carrier which is arranged on the surface of the movable sealing disk facing the control pin and which engages in the recess in the sealing disk for the control pin. A conventional sealing washer can therefore be used and yet no additional component is required. Preferably, one or both of the meeting edges of the step and the pivot holder are chamfered or rounded. Thus, a clear resistance can be felt when crossing the step, but no canting can occur.
Die Erfindung soll nunmehr anhand der beiliegenden Zeichnungen näher beschrieben werden, wobei die Fig. 1 eine erfindungsgemäße Kartusche zeigt und die Fig. 2 das durch einen strichpunktierten Kreis gekennzeichnete Detail der Fig. 1.The invention will now be described in more detail with reference to the accompanying drawings, in which FIG. 1 shows a cartridge according to the invention and FIG. 2 shows the detail of FIG. 1 identified by a dash-dotted circle.
In einem Gehäuse 1 ist eine feste Dichtscheibe 4 und eine bewegliche Dichtscheibe 3 eingesetzt, wobei Dichtungen 6 und 7, die den Kartuschenboden 5 durchsetzen, in Ausnehmungen um die Wasserdurchtritte des Kalt-, Warm- und Mischwassers in der festen Dichtscheibe 4 eingesetzt sind. Bei der Montage der Kartusche werden diese Dich- tungen 6 und 7 zusammengedrückt und bewirken einen Anpreßdruck der festen Dichtscheibe 4 auf die bewegliche Dichtscheibe 3. In der beweglichen Dichtscheibe 3 ist eine Mischkammer 8 vorgesehen, die je nach Stellung der beweglichen Dichtscheibe 3 mit den Wassereintritten und/oder dem Mischwasseraustritt in der festen Dichtscheibe 4 kommuniziert. Auf der gegenüberliegenden Oberfläche der Dichtscheibe 3, die dem Steuerhebel 11 des Einhebelmischventils zugewandt ist, befindet sich eine Ausnehmung 15, in die der Steuerzapfen 9 des Steuerhebels 11 eingreift. Der Steuerhebel 11 durchsetzt dabei den Pivothalter 10, auf welchem der Steuerhebel 11 an einer Achse 12 gelagert ist. Am Steuerhebel 11 ist der Griffhe- bel (nicht dargestellt) montiert.In a housing 1, a fixed sealing washer 4 and a movable sealing washer 3 are used, seals 6 and 7 which penetrate the cartridge base 5 being inserted in recesses around the water penetrations of the cold, warm and mixed water in the fixed sealing washer 4. When assembling the cartridge, these seals 6 and 7 are pressed together and bring about a contact pressure of the fixed sealing washer 4 on the movable sealing washer 3. A mixing chamber 8 is provided in the movable sealing washer 3, which, depending on the position of the movable sealing washer 3, enters the water and / or the mixed water outlet communicates in the fixed sealing disk 4. On the opposite surface of the sealing disk 3, which faces the control lever 11 of the single-lever mixer valve, there is a recess 15 into which the control pin 9 of the control lever 11 engages. The control lever 11 passes through the pivot holder 10 on which the control lever 11 is mounted on an axis 12. The handle lever (not shown) is mounted on the control lever 11.
Bei dem gezeigten Ausführungsbeispiel ist auf der Oberfläche der beweglichen Dichtscheibe 3 ein Dichtscheiben- träger 13 angeordnet, der im Bereich des äußeren Umfanges der beweglichen Dichtscheibe 3 eine Stufe 14 aufweist.In the embodiment shown, a sealing washer is on the surface of the movable sealing washer 3. Carrier 13 arranged, which has a step 14 in the region of the outer periphery of the movable sealing washer 3.
Beim Anheben des Griffhebels kommt es zu einer Schwenkbe- wegung des Steuerhebels 11 um die Achse 12, womit auch der Steuerzapfen 9 eine Schwenkbewegung um die Achse 12 ausführt und damit die bewegliche Dichtscheibe 3 gegenüber der festen Dichtscheibe 4 verschiebt. Dabei gleiten die zueinander gewandten Oberflächen des Pivothalters 10 und des Dichtscheibenträgers 13 aufeinander, bis die Stufe 14 im Dichtscheibenträger 13 am unteren Rand des Pivothalters 10 anschlägt. Die Höhe der Stufe 14 ist so gewählt, daß bei Aufbringen größerer Kräfte auf den Griff- hebel eine weitere Verschiebung der beweglichen Dicht- scheibe 3 erreicht wird, indem die bewegliche Dichtscheibe 3 gemeinsam mit der festen Dichtscheibe 4 gegen den Anpreßdruck der Dichtungen 6 und 7 und gegen den herrschenden Wasserdruck zum Kartuschenboden 5 hin verschoben wird und damit der untere Rand des Pivothalters 10 über die Stufe 14 im Dichtscheibenträger 13 gleiten kann. Somit wird also durch eine Erhöhung des Schiebewiderstandes an dem Punkt, wo die Stufe 14 auf den Pivothalter 10 trifft, ein "Endpunkt" für die herkömmliche Wasserentnahme ohne Bedacht auf Temperatur und Menge gesetzt. Eine Wassersparmaßnahme, die in der Kartusche integriert ist und für die kein zusätzliches Teil benötigt wird und für die daher auch kein erhöhter Montageaufwand erforderlich ist. Es entstehen bei der Fertigung der Kartuschen keine Mehrkosten, dennoch kann einfach mit dieser Vorrichtung Wasser gespart werden, ohne daß andererseits auf den Komfort eines starken Durchflusses wie bisher, wenn es gewünscht wird, verzichtet werden muß. When the handle lever is raised, the control lever 11 pivots about the axis 12, so that the control pin 9 also pivots about the axis 12 and thus displaces the movable sealing disk 3 with respect to the fixed sealing disk 4. The mutually facing surfaces of the pivot holder 10 and the sealing disk carrier 13 slide onto one another until the step 14 in the sealing disk carrier 13 strikes the lower edge of the pivot holder 10. The height of step 14 is selected so that when larger forces are applied to the handle lever, a further displacement of the movable sealing washer 3 is achieved by moving the movable sealing washer 3 together with the fixed sealing washer 4 against the contact pressure of the seals 6 and 7 and is moved against the prevailing water pressure to the cartridge base 5 and thus the lower edge of the pivot holder 10 can slide over the step 14 in the sealing disk carrier 13. Thus, by increasing the sliding resistance at the point where the step 14 meets the pivot holder 10, an "end point" for conventional water withdrawal is set without considering the temperature and quantity. A water saving measure that is integrated in the cartridge and for which no additional part is required and for which therefore no increased assembly effort is required. There are no additional costs in the manufacture of the cartridges, but water can easily be saved with this device without, on the other hand, having to forego the convenience of a high flow rate as before, if so desired.
