ABSTRACT:
The instant invention concerns a pressure medium control device for controlling the working chambers of a servo-motor, whereby said servo-motor is provided with two control valves which are actuated via actuator means through relative movements between a power input member and a power output member which is connected with said power input member by means of elastic, resilient, especially pre-stressed coupling means, and whereby the servo-motor is in operative connection with the power output member and the control valves are provided with reaction areas for reflecting the developing pressures to the power input member, and/or are in operative connection with one or a plurality of corresponding reaction members, whereby the power transmission from the power input member to the control valves, which is necessary for activating the control valves, is effected via a lost motion coupling to which a further elastic resilient coupling means is parallel-switched, especially for two control valves which are arranged transverse and off-center in a valve member, according to German Patent Application P 22 42 021.9.
