Abstract (en)
[origin: EP1462660A1] A position sensor (42) is provided for determining the position of a pilot piston (26,28). A pilot valve (44) is operated depending on the position of a working piston (14,16) and the position of the pilot piston, and controls the pilot piston. A working valve is operated exclusively by the pilot valve. Independent claims are included for a method of operating a hydraulic drive device and for a control device for use in the method.
