Abstract

See full text

For the present small solenoid valve, a stem is coupled to a solenoid plunger, and a valve body is attached to a distal end of the stem. A circular-ring shaped valve seat on which the valve body is seated is provided in a valve chamber of a valve casing, and a seal ring is externally fitted on the stem between the valve chamber and the solenoid plunger with an outer peripheral portion of the seal ring made to contact with an inner surface of the valve casing. The valve casing and the seal ring are made of a rubber-like polymer elastic body, a first port is connected to communicate with the valve chamber, and a second port is connected to communicate with an inner side of the valve seat. At actuation of the solenoid, when the stem moves in an axial direction, the seal ring follows the movement by only elastic deformation without sliding.
