Abstract

In a first position between the adjustment piston (6) and the opposite piston (7) a first chamber (18) is defined. In a second position, a second chamber (20) is formed between a wall (2a) of the cylindrical casing (2) and the second pressure surface (19) of the opposite piston. Each chamber has a supply line (14, 15) for pressurized hydraulic fluid, enabling separate pressurization. Pressurization of the first chamber exerts a greater force than pressurization of the second.
