Abstract:
1. A device for the translation of a displacement of an actuator comprising a housing, wherein a first and a second piston are held in a movable fashion, the first piston, the second piston and the housing form the boundaries of a translation chamber, the translation chamber is filled with translation medium and the position of the first piston determines the position of the second piston, the translation chamber is connected to an equalisation chamber by means of a hydraulic line, the hydraulic line equalises only pressure differences of long duration between the equalisation chamber and the translation chamber, the equalisation chamber is bounded by a first and/or second bellows, a sealing gap is formed between the housing and the second piston and is sealed by means of a third bellows, a means of tensioning is provided and this pre-tensions the second piston in a rest position, and wherein the means of tensioning is fitted in the form of a tensioning spring between the housing and the second piston.
