Abstract

In a valve actuating device ( 1 ), a bi-stable mechanism ( 13 ), by which an auxiliary valve ( 7 ) of a pressure-actuatable main valve ( 2 ) can be controlled, is set up in such a way that at least one stop point for an open position of the main valve ( 2 ) can be adjusted by a rotational movement of a valve element ( 10 ) in order to adjust a manual operating element ( 11 ) for the auxiliary valve ( 7 ).

First claim

The invention claimed is:

1. A valve actuating device ( 1 ), comprising:
a main valve ( 2 ) having a switching membrane ( 5 );
an auxiliary valve ( 7 ) configured to adjust the switching membrane between an open position and a closed position;
a bi-stable mechanism ( 13 ) having a manual operating element ( 11 ) which is movable in an actuating direction ( 12 ), the bi-stable mechanism being configured to actuate the auxiliary valve ( 7 ), the bi-stable mechanism ( 13 ) has a pairing of a stop element ( 27 ) and a stop line ( 28 ) which provides different stop positions, and which interact to define the open position, and the stop line ( 28 ) comprises a sequence of at least three segments ( 29 ), each said segment including a positive stop for receiving the stop element ( 27 ), and each said segment having a different axial position; and
wherein a switching position of the bi-stable mechanism ( 13 ) that defines an open position of the bi-stable mechanism ( 13 ) is settable by a rotational movement about the actuating direction ( 12 ) of an adjustment part ( 14 ) relative to the manual operating element ( 11 ).

2. The valve actuating device ( 1 ) as claimed in claim 1 , the adjustment part ( 14 ) is a sleeve-shaped.

3. The valve actuating device ( 1 ) as claimed in claim 1 , wherein the adjustment part ( 14 ) is arranged rotatably on a housing part ( 16 ) which accommodates the bi-stable mechanism ( 13 ).

4. The valve actuating device ( 1 ) as claimed in claim 1 , wherein the manual operating element ( 11 ) is arranged to be linearly displaceable in the actuating direction ( 12 ).

5. The valve actuating device ( 1 ) as claimed in claim 1 , wherein the adjustment part ( 14 ) and the manual operating element ( 11 ) are movable independently of one another.

6. The valve actuating device ( 1 ) as claimed in claim 1 , wherein the manual operating element ( 11 ) is guided in a rotationally fixed manner.

7. The valve actuating device ( 1 ) as claimed claim 1 , wherein a relative position of the stop element ( 27 ) on the stop line ( 28 ) is adjustable by the adjustment part ( 14 ).

8. The valve actuating device ( 1 ) as claimed in claim 7 , wherein the stop line ( 28 ) is formed without interruptions.

9. The valve actuating device ( 1 ) as claimed in claim 7 , wherein at least one rotational stop ( 33 ) for an adjustment direction of the relative position is formed, delimiting the stop line ( 28 ) in an adjustment direction ( 39 ) of the relative position.

10. The valve actuating device ( 1 ) as claimed in claim 1 , wherein the stop line ( 28 ) describes a portion of a helical line which encircles the actuating direction.

11. The valve actuating device ( 1 ) as claimed in claim 1 , wherein the bi-stable mechanism ( 13 ) comprises a ballpoint pen mechanism, and a position of a stop for a working movement of the ballpoint pen mechanism is settable by the adjustment part ( 14 ).

12. The valve actuating device ( 1 ) as claimed in claim 1 , wherein the adjustment part ( 14 ) accommodates the manual operating element ( 11 ).

13. The valve actuating device ( 1 ) as claimed in claim 7 , wherein the segments are arranged in a stepped form.

14. A valve actuating device ( 1 ), comprising:
a main valve ( 2 ) having a switching membrane ( 5 );
an auxiliary valve ( 7 ) configured to adjust the switching membrane between an open position and a closed position;
a bi-stable mechanism ( 13 ) having a manual operating element ( 11 ) which is movable in an actuating direction ( 12 ), the bi-stable mechanism being configured to actuate the auxiliary valve ( 7 ), the bi-stable mechanism ( 13 ) has a pairing of a stop element ( 27 ) and a stop line ( 28 ) which provides different stop positions, and which interact to define the open position, the stop line ( 28 ) is formed in an encircling manner and defines a lower point of reversal ( 35 ), an upper point of reversal ( 36 ), at least one rising portion ( 37 ), and at least one falling portion ( 38 ), and the at least one rising portion comprises a sequence of segments ( 29 ), with each said segment having a different axial position; and
wherein a switching position of the bi-stable mechanism ( 13 ) that defines an open position of the bi-stable mechanism ( 13 ) is settable by a rotational movement about the actuating direction ( 12 ) of an adjustment part ( 14 ) relative to the manual operating element ( 11 ).
