ABSTRACT:
The invention concerns a device for operating a mechanism (5) of a rinsing fixture, in particular for operating a closing and opening mechanism or a locking mechanism of a rinsing fixture. It shows a float (28) and a first hydraulic or pneumatic force means (15) that shows a regulating unit (16) that is controllable through a float. A second hydraulic or pneumatic force means (9), which has a regulating unit (8) that is connected hydraulically or pneumatically with the regulating unit of the first force means, has an active connection with the mechanism (5).
According to the invention it is planned that upon rising the float, in opposition to a restoring force, drives the regulating unit of the first force means for operating the mechanism, that the float upon sinking is uncoupled from the regulating unit of the first force means, and that a valve (12) is arranged in the connection (11, 13) of the two force means. The valve is controlled by the float for movement of the regulating unit of the first force moans or by an additional float, so that the connection is open upon the rising of the float, is closed off when the float has risen or is sinking and is open when the float has sunk.
