Abstract (en)
[origin: EP1111230A2] A device for transferring an actuator (8) movement on to a positioning element (3), includes a transfer/transmission element which forms a working connection between the actuator (8) and the positioning element (3), and establishes a hydraulic chamber (22) and a storage chamber (24), which are filled with a hydraulic liquid and are inter-joined via at least one throttling gap (36,37). The transfer/transmission element has a first and a second piston element (21,23;121), in which the first piston element is securely joined to the actuator (8) and the second piston element (23) is securely joined to the positioning element (3). Between the first piston element (21;121) and the second piston element (23) is formed the hydraulic chamber (22), and the storage chamber (24) comprises a pressurised storage chamber zone (242), the zonal boundaries of which are flexibly formed. The pressurised storage chamber zone is specifically restricted/limited by a bellows arrangement (25,26).
