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 sea…
