[origin: EP0909891A1] The valve piston (25) moves in a guide bore (28) with a leak path formed between the surface of the piston and the bore wall. The leak path connects a coupling chamber (30) to a low pressure chamber (18) containing a hydraulic pressure medium. A filling valve (33) is provided in the connection, located on the piston, which actuates the valve member (22). Preferably a control chamber (41) is provided between coupling chamber and filling valve,
