Abstract:
The invention provides an electromagnetic actuator for moving a closure member of a valve. The actuator contains a solenoid, a yoke and a wire spring for fixing a guide tube, in which the closure member is movable, to the solenoid. The spring is formed so that it further fixes the yoke to the solenoid. Accordingly, the number of components is reduced, and detaching of the yoke may easily be facilitated.
