Claims

[Scope of utility model registration request]

In a solenoid valve that has an electromagnetic circuit side and a main body side, and operates a plunger during excitation to selectively open and close between an import port, an out port, and an exhaust port, the main body side has an import port, an out port, and an exhaust port. a first valve seat 12 that communicates with the import in the axial direction of the plunger; and a first valve seat 12 that opens and closes the first valve seat 12.
A first valve body 6 that moves together with the plunger, a second valve seat 13 that faces in a direction perpendicular to the axial direction of the plunger, and a second valve seat 13 that opens and closes the second valve seat 13 and a second valve element 7 that engages with the valve element 6, is normally pressed by the first valve element 6, and is capable of pressing the first valve element 6 by manual operation; When the plunger is inactive, the first valve seat 12 is closed by the first valve body 6 to close the space between the import and the out ports, and the second valve body 7 is closed by the first valve seat 12. When the plunger is in operation or manually operated, the first valve seat 12 is opened by the first valve body 6 to communicate the out port and the exhaust port. The electromagnetic valve is characterized in that the second valve element 7 closes the second valve seat 13 to close the out port and the exhaust port.
