The hydraulic system has an adjustable pump for delivering pressure fluid to a plurality of loads, multiway control valve assigned to respective loads and means for adjusting the flow of the pressure fluid to the working conditions of the loads, the adjusting device includes measuring throttles provided in the switching passages of respective control valves and a flow regulating device having a differential piston displaceable by the pressure difference at the outlet of the pump and at the outlet of the measuring throttle of the activated control valve. Th differential piston controls a branched stream of high pressure fluid from the pump to control an actuator in the form of a cylinder and piston unit mechanically coupled to the adjusting member for the pump. |
