Abstract

A hydraulic servo-motor has an adjusting piston (10) coupled through a P-member spring (14) with a governor slide valve (21) for the adjusting piston (10). A return chamber (27) is formed between the slide valve (21) and a return piston (26). The return piston is supported by a restoring spring (28) disposed between the adjusting piston (10) and the spring (28). So that the P-region of the motor may be varied, an adjustable throttle (32) is provided in a line (30) connecting the return chamber (27) with a chamber (17) of an overflow valve (16) which determines fluid pressure downstream of a fixed constriction (31) in accordance with the force exerted by the P-member spring (14) on a valve body (15) of the overflow valve (16). <IMAGE>
