Abstract
PURPOSE: To provide a direction control valve of small pressure loss, by connecting through an orifice an outlet passage extending to a tank, to an inlet passage extending from a pump when the valve is in its neutral position and by shortening the after-run time of an electric motor.
CONSTITUTION: A direction control valve V is installed in a working fluid circuit 4, which connects an actuator 3 to a pump 2 which is driven by an electric motor 1. The valve V controls the direction of flow of a working fluid. The valve V regulates the opening and closing of a switch 5 for the electric motor 1 to open the switch when the valve is in its neutral position. An inlet passage 4a extending from the pump 2 and an outlet passage 4b extending to the a tank 6 are connected to each other through an orifice 7 when the direction control valve V is in the neutral position.
