Abstract

A control rod (16) of a control member (19) is preloaded by a spring (23) in the direction of the maximum displacement volume (Qmax) of a hydraulic pump. A regulator piston (21) displaceable in a regulator cylinder (20) counteracts the spring (23). Without switching on the consumer (32), the regulator cylinder (20) is acted upon via a regulator line (44) in such a way that the hydraulic pump (14) is adjusted at least approximately to the minimum displacement volume (Qmin). When the consumer (32) is subsequently switched on, the regulator cylinder (20) is connected to the tank via a second directional control valve (42), which can be changed over from the pressure line (24), and a second return line (35) having a restrictor (36). The control rod (16) is thereby adjusted in a controlled manner in the direction of Qmax. A non-return valve (39) can be connected in a branch line (38). A pressure-reducing valve (40) can also be connected in this branch line (38). Furthermore, a hydraulic accumulator (41) and/or a pressurising valve (51 52) and/or a separate hydraulic pump (48) with a feed line (38') to the regulator line (44) can be provided.
