Definitions

  • the invention relates to a dispensing valve for aerosol cans according to the preamble f of patent claim 1.
  • a dispensing valve of this type is known from DE-PS 28 17393.
  • An aerosol can equipped with this dispensing valve can be used in any position.
  • the flow channels of this dispensing valve cannot be cleaned by the propellant content of the aerosol can. Such cleaning is necessary, however, if the contents can clog the flow channels.
  • the invention is therefore based on the object of specifying a delivery valve for aerosol cans which is of simple construction and which can be produced cost-effectively and which ensures the trouble-free delivery of a medium which tends to block the flow channels using essentially known parts.
  • the dispensing valve should enable regulation of the dispensing quantity of the liquid filling material and / or the propellant gas if necessary.
  • dispensing head is positively and tightly placed on the valve stem and the valve stem is mounted in a rotary valve in the valve housing, which opens the additional opening at one end point of its range of rotation and closes at the other end point.
  • the dispensing valve enables thorough cleaning of the flow channels, in particular the flow channels in the valve stem and in the dispensing head, by means of the propellant. Guarantee gas content of the aerosol can without significant loss of the liquid contents.
  • the dispensing valve enables spraying both in the normal upright use position (normal position) and in the reverse position (overhead position) of the aerosol can. In this case, even with high propellant gas pressure, the additional opening is securely closed by the manually adjustable rotary slide valve, so that there is a high level of operational reliability.
  • the dispensing valve according to claim 2 enables safe spraying in the overhead position of the aerosol can, since the rotary valve reliably closes the main opening.
  • the rotary valve allows the flow channels in the valve stem and in the dispensing head to be easily cleaned after the spraying process.
  • the main opening is closed and the additional opening is opened by turning the dispensing head and the rotary slide valve connected to it.
  • the discharge valve is opened, only propellant gas is then released, the residual liquid is blown out of the flow channels and thus cleaned.
  • the dispensing valve according to claim 3 is favorable for cases in which a regulation of the dispensing quantity of the liquid filling material is desired, e.g. in order to provide a substrate with very thin layers of the filling material.
  • this embodiment allows regulation of the amount of discharge of the propellant gas. For example, this
  • the quantity to be dispensed to save propellant gas can be reduced if the filling material is a low-viscosity and less sticky liquid, so that a smaller amount of propellant gas is sufficient to clean the flow channels after spraying.
  • the dispensing valve in accordance with claim 4 has the advantage that the supplementary opening is open in a certain range of rotation of the rotary valve, both the main opening as and additionally 'of these openings can be changed ver ⁇ also the je ⁇ stays awhile passage cross-section. This makes it possible to continuously reduce the quantity of liquid filling and to increase the proportion of propellant in the spray jet. This can also be done in the overhead position of the aerosol can.
  • the spray jet can be varied in this way from a concentrated liquid jet to a fine atomized aerosol jet.
  • the properties of the dispensing valve can be further used only by using a different rotary valve with differently designed flow channels, but while maintaining the other parts, such as the valve housing, valve stem and dispensing head areas to adapt.
  • the rotary valve has a very convenient shape. It can be essentially cylindrical and is therefore well guided in the valve housing.
  • the longitudinal recesses can be made at the desired position on the rotary slide without difficulty.
  • the dispensing valve according to claim 6 is advantageous because such a longitudinal recess can be arranged in the rotary slide valve in the vicinity of the main opening and the additional opening by the presence of two longitudinal recesses j . It is then sufficient even a small angle of rotation of the rotary valve to switch to the dispensing valve ⁇ from the spray position for the liquid product to the spray position Q for the propellant gas (cleaning position). This is particularly clear in the case in which the main opening and the additional opening are offset by approximately 180 ° with respect to the rotary slide circumference. 5
  • the dispensing valve according to claim 7 relates to an embodiment in which a large amount of propellant gas can be added to the dispensed liquid. Thereby e.g. received a particularly broad and relatively dry spray jet.
  • the amount of propellant gas which can be mixed with the liquid dispensed is infinitely variable.
  • the dispensing valve according to claim 8 has an essentially cylindrical rotary slide valve which is mounted in the valve housing.
  • the control edge of the rotary valve ensures in the area of the additional opening a particularly fine control of the amount of substance that passes through the additional opening when spraying.
  • the dispensing valve according to claim 9 enables simplified operation of the rotary slide valve, in particular its positions which correspond to the end points of its rotary range being found quickly.
  • such rotary valves can be used, which either open the main opening or the additional opening, or rotary valves which have a longitudinal recess in the area of these openings with a larger passage cross-section, so that both the main opening and the additional opening are open in a rotary section.
  • the dispensing valve according to claim 11 is easy to manufacture and operationally reliable even with frequent use
  • the dispensing valve according to the invention is particularly suitable for spraying liquids which are relatively highly viscous, sticky or quick-drying or have a high content of fillers. Such liquids tend to clog the flow channels in the valve stem and in the dispensing head and must therefore be blown out of these channels by propellant gas half after the spraying process.

Abstract

Une valve de dosage pour bombe aérosol comprend une boîte à soupape (1) qui comporte une chambre libre intérieure (10), une ouverture principale (7), une ouverture supplémentaire (20) ainsi qu'une tige de soupape (4). Cette ouverture supplémentaire relie en position normale de la bombe aérosol sa chambre de gaz propulseur avec ladite chambre libre intérieure et peut être obturée. Ladite tige de soupape porte à l'extérieur de la boîte à soupape (1) une tête de dosage et est logée pour être axialement déplaçable à l'intérieur de la boîte à soupape (1). Cette tige est en outre maintenue en position de fermeture de la valve de dosage par un ressort à pression (11). En cette position fermée de la valve, la chambre libre intérieure (10) est maintenue étanche à l'aide d'un anneau de garniture (16) qui s'appuie contre un forage transversal (18) situé dans ladite tige (4). Cette dernière est reliée par un canal d'écoulement (19) avec la tête de dosage et a ceci de particulier que ladite tête de dosage y est apposée étanchement et en solution de continuité et qu'elle est fixée solidaire en rotation dans un tiroir rotatif (2) dans la boîte à soupape (1). Ce tiroir rotatif ouvre ou respectivement ferme ladite ouverture supplémentaire (20) en chacune de ses fins de course.
