Abstract

PURPOSE:To reduce risk of damage to the device caused by vibrations of a heavy electric magnet etc. by furnishing electric magnet and actuator in such a way that their working axes are perpendicular to each other, fixing the magnet to the exterior surface of the upper wall of actuator, and thereby approaching their centers of gravity. CONSTITUTION:A solenoid operated valve 10 is composed of an electric magnet part 11 and a valve case 12. The solenoid operated valve 10 and an actuator are fixed to the upper case 1a of the actuator with their working axes crossing perpendicularly through such a procedure as screw-fitting the flange part 12c of the valve 10 with a screw 12d. Accordingly, the center of gravity of the valve can be approached sufficiently to the external surface of the upper wall of the upper case of actuator, so that the inertia force produced when vibrations are applied to the electric magnet device does not cause any delamination at the fixation part of the valve with actuator or of the electric magnet part of solenoid operated valve with the valve case nor any crack at the plastic resin parts.
