Abstract

PURPOSE: To improve pressure compensation precision by interposing a normally- closed type pilot valve in the vent passage of a shunt type pressure control valve and then by controlling the opening degree of the pressure control part of the pressure control valve by the pilot valve.
CONSTITUTION: In vent passage 21 of shunt type pressure control valve 13 of a flow pressure controller on a meter-in circuit system provided with function of flow control and pressure compensation, normally-closed type pilot valve 14 is interposed. Then, pilot chamber 22 of valve 14 is arranged in front of flow control element 15, and back pressure chamber 28 of valve 14 is behind element 15; and shunt line 20 is linked to discharge control mechanism 32 of variable pump 11, the pressure source of main line 18, and throttle 34 is provided to line 33 shunted from line 20 to tank 19a. Then, the opening degree of pressure control part 27 of control valve 13 is controlled by valve 14 operating a difference in pressure across element 15 so as to reduce the flow rate of valve 14, and consequently an influence of a propellant is lessened to improve pressure compensation precision.
