Abstract
A device for transmitting a displacement of an actuator to a setting element comprises two pistons that delimit two transmission chambers and a compensation chamber with a housing. The compensation chamber is hydraulically connected to the two transmission chambers. The transmission chambers transmit a displacement of the first piston in order to effect a displacement of the second piston. The compensation chamber serves as a reservoir for the transmission medium with which the transmission chambers are filled. The compensation chamber is delimited by an elastomer ring. The elastomer ring depicts a simple and economical realization with which it is possible to subject the compensation chamber to the action of pressure and to change the volume of the compensation chamber at the same time. In a preferred embodiment, the elastomer ring is externally subjected to the action of a tension force via a pressure ring.
