Claims

[Scope of utility model registration request]

In the valve chamber, one of the inflow hole and the outflow hole, which are substantially perpendicular to each other, has an opening on the side of the valve chamber as a valve port, and a valve seat is formed on the edge of the valve port, and a pressure chamber having substantially the same diameter as the valve port is formed as a valve seat. A valve body formed opposite to the opening and tightly and slidably fitted into the pressure chamber opens and closes the valve opening by coming into contact with and separating from the valve seat, and is attached to the pressure chamber. The elasticity of the spring urges the valve body in the valve closing direction, and the valve stem, which is reciprocated by the drive of the electric actuator, is locked to the valve body and the valve body is pushed against the elasticity of the spring. An electric on-off valve, characterized in that the electric on-off valve is actuated in the valve-opening direction, and has a communication hole formed in the valve body for communicating the pressure chamber and the valve port.
