Definitions
- the invention relates to a pneumatic actuator, comprising a housing which is connectable to a pneumatic line and in which a pusher piston is mounted, which forms an interior with the housing and the example, by means of a key against the force of a spring from a first position in a second position is movable, wherein the interior space is reduced and the displaced from the interior air can escape through a vent valve and being displaceable by the spring of the pusher piston for generating a negative pressure in the interior of the second to the first position.
- An actuator of this type is known in the art by the EP-A-1 491 620 known.
- This has a housing which is closed with a lid and having an output to which a pneumatic line can be connected.
- a pusher piston is mounted, which is displaceable by means of a key against the force of a spring arranged in the housing for generating an air pulse.
- On the pusher piston according to a variant of a vent valve is arranged so that when moving the pusher piston air from the housing interior can escape to the outside.
- the return of the pusher piston by means of the spring is in the housing Produces negative pressure, which is used via the pneumatic line to open a purge valve.
- the operating force and the pusher stroke are comparatively large.

- the actuator should still be reliable.
- the object is achieved in a generic pneumatic actuator characterized in that the pusher piston is sealed at its periphery with a rolling diaphragm relative to the housing and mounted thereon.
- the rolling diaphragm due to the sealing by means of the rolling diaphragm, even a comparatively large inclined position of the pusher piston can not lead to jamming, since the rolling diaphragm is very flexible on the circumference of the pusher piston. Jamming is not possible even if the pusher piston is built with a much larger effective area than before. On the one hand, this allowed a flatter design and, on the other hand, a shorter pusher stroke. This is particularly advantageous when operated with a button.
- the rolling diaphragm allows a substantially resistance-free displacement of the pusher piston, so that the operating force is not increased by friction and therefore can be minimized.
- a cover is arranged on the housing and that the rolling diaphragm is clamped at its periphery between the housing and the lid. With the rolling diaphragm can then be sealed at the same time the lid relative to the housing. This is preferably done with an am Scope of the rolling diaphragm arranged bead. This allows easy installation and cost-effective production.

- this handle plunger is preferably moved first, so that the vent valve is opened.
- the handle plunger is preferably mounted in the housing and thus not in the lid. This allows an accurate and easier management of the handle plunger.
- a negative pressure can be generated for actuating, for example, a flushing valve.
- the handle plunger is guided displaceably on a bottom of the housing.
- the leadership of the handle plunger on a guide member, the pin or peg-shaped is centrally located in the ground.
- the handle plunger has a recess in which the guide part is guided.
- the spring is conical, so that can be compressed substantially in one plane. This allows a particularly flat design.
- an annular interior space is formed between a bottom of the housing and an inside of the pusher piston when the pusher piston is in the second position and that the spring can be arranged flat in a plane compressed in this interior.
- the handle plunger on a side facing the pusher piston has a sealing edge which seals the handle plunger against the pusher piston during the return stroke.
- the sealing edge may, for example, circular and coaxial with the axis of displacement be arranged.
- the seal is particularly dense when this sealing edge can be applied to the rolling diaphragm.
- the rolling diaphragm is then preferably formed to extend over a substantial portion of the inside of the pusher piston.
- the invention also relates to a sanitary device with an actuating device according to claim 1.
- This has a flush valve, which is actuated with negative pressure.
- the operation is preferably carried out by means of a button which is pivotally mounted in a frame.
- FIG. 1 shows a flushing device 38, for example, for a urinal, not shown here, which has a purge valve 2 in a box 3, which has a water channel 39 with an inlet 4 and arranged therein a shut-off valve 7.
- a purge valve 2 With the shut-off valve 7 open and the flush valve 2 open, water passes from the inlet 4 through a Filter 6 through the purge valve 2 in a flushing pipe 5 and then in the sanitary body.

- a frame 31 is arranged, in which the key 32 is pivotally mounted.
- the lid 12 is fixedly connected to the housing 10, for example with screws not shown here.
- a bead 27 of a membrane 26 the lid 12 is sealed airtight relative to the housing 10.
- the membrane 26 is a rolling diaphragm to which a pusher piston 24 is attached.
- This pusher piston 24 is provided with a pusher piston plate 25, which is connected flat with the membrane 26, for example glued or welded.
- In the middle of the pusher piston 24 has a head 29 which extends through a passage 13 of the lid 12 to the outside of the inside of the button 32 out.
- the sleeve-shaped head 29 in turn has in the middle a passage 42 through which a head 23 of a handle plunger 20 extends. Between the two heads 23 and 29, a gap 44 is arranged, which forms a vent valve with the handle plunger 20.

Abstract
Description
Die Erfindung betrifft eine pneumatische Betätigungsvorrichtung, mit einem Gehäuse, das an eine pneumatische Leitung anschliessbar ist und in dem ein Drückerkolben gelagert ist, der mit dem Gehäuse einen Innenraum bildet und der beispielsweise mittels einer Taste gegen die Kraft einer Feder von einer ersten Position in eine zweite Position bewegbar ist, wobei der Innenraum verkleinert wird und die aus dem Innenraum verdrängte Luft durch ein Entlüftungsventil austreten kann und wobei durch die Feder der Drückerkolben zum Erzeugen eines Unterdrucks im Innenraum von der zweiten in die erste Position verschiebbar ist.The invention relates to a pneumatic actuator, comprising a housing which is connectable to a pneumatic line and in which a pusher piston is mounted, which forms an interior with the housing and the example, by means of a key against the force of a spring from a first position in a second position is movable, wherein the interior space is reduced and the displaced from the interior air can escape through a vent valve and being displaceable by the spring of the pusher piston for generating a negative pressure in the interior of the second to the first position.
Eine Betätigungsvorrichtung dieser Art ist im Stand der Technik durch die
Der Erfindung liegt die Aufgabe zu Grunde, eine Betätigungsvorrichtung der genannten Art zu schaffen, die mit flacherer Bauform herstellbar und die zudem eine Betätigung mit einem kürzeren Drückerhub und einer kleineren Betätigungskraft ermöglicht. Die Betätigungsvorrichtung soll trotzdem funktionssicher sein.The invention is based on the object to provide an actuating device of the type mentioned, which can be produced with flatter design and also allows an operation with a shorter pusher stroke and a smaller actuation force. The actuator should still be reliable.
Die Aufgabe ist bei einer gattungsgemässen pneumatischen Betätigungsvorrichtung dadurch gelöst, dass der Drückerkolben an seinem Umfang mit einer Rollmembran gegenüber dem Gehäuse abgedichtet und an diesem gelagert ist. Bei der erfindungsgemässen Betätigungsvorrichtung kann aufgrund der Abdichtung mittels der Rollmembran eine auch eine vergleichsweise grosse Schrägstellung des Drückerkolbens nicht zu einem Verklemmen führen, da die Rollmembran am Umfang des Drückerkolbens sehr flexibel ist. Ein Verklemmen ist auch dann nicht möglich, wenn der Drückerkolben mit einer wesentlich grösseren Wirkfläche als bisher gebaut wird. Dies ermöglichte einerseits eine flachere Bauweise und anderseits einen kürzeren Drückerhub. Dies ist insbesondere bei einer Betätigung mit einer Taste vorteilhaft. Die Rollmembran ermöglicht eine im wesentlichen widerstandslose Verschiebung des Drückerkolbens, so dass die Betätigungskraft nicht durch Reibung erhöht wird und deshalb minimal gehalten werden kann.The object is achieved in a generic pneumatic actuator characterized in that the pusher piston is sealed at its periphery with a rolling diaphragm relative to the housing and mounted thereon. In the case of the actuating device according to the invention, due to the sealing by means of the rolling diaphragm, even a comparatively large inclined position of the pusher piston can not lead to jamming, since the rolling diaphragm is very flexible on the circumference of the pusher piston. Jamming is not possible even if the pusher piston is built with a much larger effective area than before. On the one hand, this allowed a flatter design and, on the other hand, a shorter pusher stroke. This is particularly advantageous when operated with a button. The rolling diaphragm allows a substantially resistance-free displacement of the pusher piston, so that the operating force is not increased by friction and therefore can be minimized.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass auf dem Gehäuse ein Deckel angeordnet ist und dass die Rollmembran an ihrem Umfang zwischen dem Gehäuse und dem Deckel eingespannt ist. Mit der Rollmembran kann dann gleichzeitig der Deckel gegenüber dem Gehäuse abgedichtet werden. Dies erfolgt vorzugsweise mit einem am Umfang der Rollmembran angeordneten Wulst. Dies ermöglicht eine einfache Montage und kostengünstiger Herstellung.According to a development of the invention it is provided that a cover is arranged on the housing and that the rolling diaphragm is clamped at its periphery between the housing and the lid. With the rolling diaphragm can then be sealed at the same time the lid relative to the housing. This is preferably done with an am Scope of the rolling diaphragm arranged bead. This allows easy installation and cost-effective production.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass ein Entlüftungsventil vorgesehen ist, das einen Drückerstössel aufweist, der bezüglich des Drückerkolbens verschiebbar ist und der beim verschieben des Drückerkolbens von der ersten in die zweite - Position einen durch den Drückerkolben verlaufenden Durchgang freigibt. Bei einer Betätigung wird vorzugsweise dieser Drückerstössel zuerst bewegt, so dass das Entlüftungsventil geöffnet wird. Der Drückerstössel ist vorzugsweise im Gehäuse und somit nicht im Deckel gelagert. Dies ermöglicht eine exakte und einfachere Führung des Drückerstössels. Mit der Betätigungsvorrichtung nach dieser Ausführung kann zur Betätigung beispielsweise eines Spülventils ein Unterdruck erzeugt werden.According to a development of the invention it is provided that a vent valve is provided which has a handle plunger, which is displaceable with respect to the pusher piston and which releases a passage extending through the pusher piston when the pusher piston is displaced from the first to the second position. When actuated, this handle plunger is preferably moved first, so that the vent valve is opened. The handle plunger is preferably mounted in the housing and thus not in the lid. This allows an accurate and easier management of the handle plunger. With the actuating device according to this embodiment, a negative pressure can be generated for actuating, for example, a flushing valve.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Drückerstössel an einem Boden des Gehäuses verschieblich geführt ist. Vorzugsweise erfolgt die Führung des Drückerstössels an einem Führungsteil, der Stift oder Zapfenförmig mittig im Boden angeordnet ist. Vorzugsweise ist hierbei vorgesehen, dass der Drückerstössel eine Vertiefung aufweist, in welcher der Führungsteil geführt ist.According to a development of the invention it is provided that the handle plunger is guided displaceably on a bottom of the housing. Preferably, the leadership of the handle plunger on a guide member, the pin or peg-shaped is centrally located in the ground. Preferably, it is provided in this case that the handle plunger has a recess in which the guide part is guided.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass die Feder konisch ausgebildet ist, so dass im wesentlichen in eine Ebene zusammengedrückt werden kann. Dies ermöglicht eine besonders flache Bauform. Hierbei ist vorzugsweise vorgesehen, dass zwischen einem Boden des Gehäuses und einer Innenseite des Drückerkolbens ein ringförmiger Innenraum gebildet wird, wenn sich der Drückerkolben in der zweiten Position befindet und dass die Feder flach in einer Ebene zusammengedrückt in diesem Innenraum angeordnet werden kann.According to a development of the invention it is provided that the spring is conical, so that can be compressed substantially in one plane. This allows a particularly flat design. Here, it is preferably provided that an annular interior space is formed between a bottom of the housing and an inside of the pusher piston when the pusher piston is in the second position and that the spring can be arranged flat in a plane compressed in this interior.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Drückerstössel auf einer dem Drückerkolben zugewendeten Seite eine Dichtungskante aufweist, die beim Rückhub den Drückerstössel gegenüber dem Drückerkolben abdichtet. Dadurch ist eine besonders dichte Verbindung des Drückerkolbens mit dem Drückerstössel beim Rückhub möglich. Die Dichtungskante kann beispielsweise kreisförmig und koaxial zur Verschiebungsachse angeordnet sein. Die Abdichtung ist dann besonders dicht, wenn diese Dichtungskante an die Rollmembran anlegbar ist. Die Rollmembran ist dann vorzugsweise so ausgebildet, dass sie sich über einen wesentlichen Bereich der Innenseite des Drückerkolbens erstreckt.According to a development of the invention it is provided that the handle plunger on a side facing the pusher piston has a sealing edge which seals the handle plunger against the pusher piston during the return stroke. As a result, a particularly tight connection of the pusher piston with the handle plunger during the return stroke is possible. The sealing edge may, for example, circular and coaxial with the axis of displacement be arranged. The seal is particularly dense when this sealing edge can be applied to the rolling diaphragm. The rolling diaphragm is then preferably formed to extend over a substantial portion of the inside of the pusher piston.
