Claims

[Scope of utility model registration request]

A body having an input port, a signal port, and an output port, a diaphragm dividing the inside of the body into a first pressure chamber communicating with the signal port and a second pressure chamber communicating with the output port and the input port, the first pressure a spring tensioned in the chamber to urge the diaphragm toward the second pressure chamber; and a valve body fixed to the other end of a shaft having one end fixed to the diaphragm; In the switching valve that controls opening and closing of communication between the output port and the input port by balancing the biasing force of the spring, the valve body is slidably disposed on the shaft, and the valve body is slidably disposed on the shaft, and the valve body is slidably disposed on the shaft, and A switching valve characterized in that a valve spring is provided to bias the valve body in a valve closing direction.
