ABSTRACT:
A solenoid valve having a movable member being moved by an electromagnetic attraction of a solenoid section in a valve chest between the solenoid section. A valve seat opposed thereto and a valve body provided an the movable member is abutted against or separated from the valve seat to close or open a valve port or ports. The movable member is supported in the valve chest through a support member or members for regulating a displacement of the movable member in a direction perpendicular to the moving direction of the movable member. The valve body may be fixed to or movable from the movable member. The movable member is formed with a through-hole for receiving the valve body, which extends in the moving direction thereof. The valve body, formed of an elastic material, is disposed in the through-hole and a surface of the valve body, which is opposed to the solenoid section forms a surface of the movable member, which is abutted against the solenoid section. There are provided a first valve port formed on the solenoid section side and a second valve port opposed thereto. The valve body need not be fixed to the movable member so that the valve body is moved toward the second valve seat without being influenced by the movement of the movable member toward the second valve seat. One surface of the valve body is abutted against or separated from a first valve seat of the first valve port to close or open the first valve port and the other surface of the valve body is abutted against or separated from a second valve seat of the second valve port to close or open the second valve port.
