Claims

[Scope of utility model registration request]

□ An input valve seat that communicates the input port with the output port 1, and a discharge valve seat that communicates the output port with the discharge port are arranged in an opposing state, and the valve discs arranged in rotation are driven by a solenoid. Accordingly, in a solenoid valve that alternately opens and closes both valve seats, the connecting rod portion of the support to which the valve body is attached is led out to a position isolated from the main flow path of the fluid, and is brought into contact with the armature of the solenoid. A seat and a spring seat for urging the valve body toward the discharge valve seat are located at a position separated from the main flow path of the fluid between the plate provided at the tip of the valve body and the spring seat behind the discharge valve seat in the valve body. In addition to compressing the spring, a return spring is compressed between the armature and the core to bias the valve body toward the input valve seat against the biasing force of the seat spring. A 3-port solenoid valve characterized by a spring with a greater biasing force than a seat spring.
