Claims

[Scope of utility model registration request]

A valve body that is connected to the discharge side of a pump driven by a motor and has a passage that communicates a pressure regulation port and a spillage port, and a valve seat that is seated toward a valve seat provided on the pressure regulation port side in the passage. The pressure regulating valve is composed of a valve body that compresses the valve body and a pressure regulating member that compresses a resilient body between the valve body, and the handle is attached to the inner surface of the handle rotatably attached to the valve body. A cam groove having an appropriate number of steps is formed concentrically with the rotation center of the
In this notch type pressure regulating valve in which a guide shaft protruding from the pressure regulating member is brought into contact with the cam groove as a driven joint, a cam portion having a stepped portion is formed on the inner circumferential surface of the handle; A displacement-sensing switch, which is built into the electric circuit of the motor so that it can be connected and disconnected, is disposed on the opposing handle support part so that its displacement-sensing part comes into contact with the cam part, and the pressure can be adjusted by rotating the handle. A notch type pressure regulating valve that can be linked to start and stop of the motor.
