Claims

[Scope of utility model registration request]

A high-pressure circuit and a return circuit for hydraulic oil are connected to the valve holes provided in the main body through respective communication ports, and a valve stem with a circumferential groove that can open and close the communication ports alternately is slidably inserted into the valve holes. In a hydraulic circuit switching solenoid valve in which this valve stem and an electromagnetic rod operated by a solenoid coil are serially connected by a connecting rod, a sleeve fixed to the main body is placed under the action of a return spring. A connecting body is slidably fitted into the connecting body, and the head of the valve stem and the lower end of the connecting rod are housed in opposition to each other, and the head and the lower end are A slight gap is provided between the opposing surfaces and between the head and the connecting body, the head of the valve stem is supported on the bottom of the connecting body, and the lower end of the connecting rod is connected to the connecting body, On the other hand, a hydraulic circuit switching solenoid valve is characterized in that a manual operator is attached to the electromagnetic rod with the upper end of the connecting rod fixed.
