Abstract

PURPOSE: To improve the vibrationproof property of the electromagnetic valve when the valve is out of operation by forming a vacant space with an end of a bellows united to the end of the valve shaft and providing a change-over valve for supplying pressure into the vacant space.
CONSTITUTION: While an electromagnetic coil 12 is in its nonexcited state, a valve body 23 is held seated on a valve seat 21e by the restoring force of a spring 35 a valve hole 21d is in the fully closed state, and a valve hole 22a is in the fully opened state. At this time, the positive pressure of air forced from an air pump is provided in the vacant space R1 of a bellows 36 through a communication hole 63a, a passage 65, a valve hole 61 and a hole 30a, so that the shaft 30 is held urged to the right. Thus, the shaft 30 is held urged to the right by the spring force of a spring 31 and the positive pressure provided in the vacant space R1 of the bellows 36, so that the movements of a movable core 15 and the shaft 30 can be reliably restricted even if the electromagnetic valve 100 experiences vibrations or shocks.
