Claims

[Scope of utility model registration request]

A valve body with a valve chamber inside, an inlet and an outlet that communicate with each other through a valve port provided in the valve body and facing the valve chamber, and a valve body housed in the valve chamber to open and close the valve port. , a solenoid plunger that interlocks this valve body,
a pressure equalizing chamber that is not in communication with the inlet and is formed by partitioning the valve chamber with a partition membrane made of an elastic material on the back of the valve body;
a pressure equalizing passage that communicates the pressure equalizing chamber with the outlet; the effective area of the valve body with respect to the pressure equalizing chamber and the effective area of the valve body with respect to the valve port are set to be the same; The solenoid valve is characterized in that the valve body is brought into contact with the valve and the mouth by the elastic force of the partition membrane.
