Claims

[Claims for Utility Model Registration] (1) A first port that defines a valve chamber and opens into the valve chamber, a second port that opens opposite the first port, and a third port that opens into the valve chamber. a housing in which a port is formed; a spherical valve body accommodated in the valve chamber of the housing to selectively close the first port and the second port; a plate-shaped support member disposed substantially perpendicularly to the axis connecting the second port to support the spherical valve body and bias the spherical valve body toward the second port; A solenoid valve comprising: a plunger that is inserted through the spherical valve body with a predetermined gap and abuts the spherical valve body; and a solenoid that drives the plunger in the direction of the spherical valve body when energized. (2) The electromagnetic valve according to claim 1, wherein the support member is a leaf spring having at least a portion in contact with the spherical valve body. (3) the support member is a diaphragm,
2. The electromagnetic valve according to claim 1, wherein the spherical valve body is fixed to a substantially central portion of the diaphragm.
