Abstract
PURPOSE: To improve responsibility to increasing direction of discharging rate in such a way that in a contrivance to control discharging rate from a discharging rate variable pump by means of a pressure control valve, preferential pressure compensation can be done on the specific one among a plurality of actuators.
CONSTITUTION: A discharging rate variable pump 1 is controlled with its discharging rate in such a way that a swash plate 2, etc. is displaced by a cylinder 4. At the same time as discharging fluid by means of the pump 1 is fed from a main flow circuit 8 via a shunt control part Z of a selective type pressure control valve 43 and a flow direction control valve 10 to an actuator 50, when a throttle decompression control part Y is selected by displacement of a spool of the pressure control valve 43, it is constituted so that pressured fluid is fed through flow direction control valves 10X, 10Y to actuators 50x, 50y. A triple port type pressure control valve 30 is provided on the side of the valve 10, the cylinder 4 is connected through a line 29 to its secondary port 25, and the valve 30 is controlled by the pressure difference in the front and in the rear of a flow rate adjusting variable orifice 19 in the valve 10.
