Abstract
PURPOSE: To simplify the structure and prevent the generation of an impact pressure in a device which electrically controls a differential cylinder provided as a pilot cylinder for driving a main valve by controlling the differential cylinder by means of an electromagnetic proportional pressure control valve.
CONSTITUTION: A main valve 10 is provided as a 3-position and 6-port value in a hydraulic line P between a hydraulic pump and a hydraulic actuator, and a pilot pressure line PP is branched from the said line P. This line PP is provided with a normally-closed electromagnetic valve 13 and a reducing valve 14 so that a pilot pressure may be introduced into a differential cylinder 15. The inside of the differential cylinder 15 is partitioned into two pressure chambers 17 and 18 by a differential piston 16. The line PP is branched via a throttle valve 19, and connected to the pressure chamber 17 and the inlet port of an electromagnetic proportional pressure control valve 20 controlled by a control circuit 24. After the outlet port of the valve 20 is connected to the pressure chamber 18 and the inlet port of the electromagnetic proportional pressure control valve 21, the outlet port of the said valve 21 is connected to a return line R.
