[Function] The valve element is in the retracted position by receiving the spring force of the spring.
The fluid passage is open. When the fluid is sent to the fluid passage in this state, the fluid flows into the communication passage formed in the valve body at the same time as flowing through the fluid passage, and enters the valve chamber through the communication passage. In the valve body, since the pressure receiving area on the valve chamber side is larger than the pressure receiving area on the fluid passage side, the valve body receives the fluid pressure due to the pressure receiving area difference between the valve chamber side and the fluid passage side and is urged in the forward direction. However, as long as the load generated by the fluid pressure does not exceed the load of the spring, the valve body does not advance, the fluid passage is kept open, and the fluid flows through the fluid passage. When the load generated by the fluid pressure in the fluid passage exceeds the load of the spring, the pressure of the fluid entering the valve chamber causes the valve body to advance against the elastic force of the spring, thereby causing the fluid passage to move. Shut off and fluid flow stops. Then, when the fluid pressure in the fluid passage is removed and the load generated by the fluid pressure becomes smaller than the load of the spring, the valve body is automatically retracted by the spring force of the spring, and the fluid passage is opened. Fluid flows.
