Abstract

PURPOSE:To obtain high responsive quality of pressure control, by performing delivery control through selection of a pressure compensator valve and controlling a flow of oil not to be disturbed with a throttling or the like also when selected to the feed of control oil presure. CONSTITUTION:Pressure is increased in a load line 15 to operate a remote control relief valve 12 and flow oil into a tank 14, then difference pressure DELTAP is generated in a throttling 11 to overcome a spring 18, and a pressure compensator valve 13 is selected to a right side position to communicate a control actuator 10a to the tank 14. Simultaneously, since a flow of oil from a pilot pipe line 16 is disturbed by a throttling 17, oil is rapidly discharged from the control actuator 10a to the tank 14, and a recovery actuator 10b is driven, then an eccentricity amount of vanes 20 is changed toward a zero position. In consequence, a delivery amount is throttled to suppress a load of the load line. In this way, high responsive quality of pressure control can be obtained.
