Abstract

PURPOSE: To eliminate an electric circuit for feed back, by connecting a solenoid control valve and solenoid reducing valve with a liquid chamber of actuator for driving a directional control valve and feeding the pressure in the chamber back to both valves.
CONSTITUTION: When a piston 9 of an actuator is shifted leftward, a solenoid control valve 25 is switched to "close" and a solenoid reducing valve 26 to "full open" u. Pressure oil from a liquid pressure source p flows in a liquid chamber 11 through the reducing valve 26, liquid in a liquid chamber 10 flows in a tank through a solenoid valve 24, and the piston 9 is shifted to the left. As the piston 9 shifts, the pressure in the liquid chamber 11 rises due to a spring 3. This pressure works on spools of the valves 25, 26 to return them to their former positions and the piston 9 is positioned. The same sequence is followed for shifting the piston to the right.
