Abstract: The invention provides an electromagnetic actuator (1) for moving a closure member of a valve (13). The actuator contains a solenoid (2), a yoke (11) and a wire spring (7) for fixing a guide tube (4), 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.

Abstract: The invention provides a valve comprising a tube (2) for guiding movement of a plunger, a solenoid (3) which can be arranged about the tube, and a yoke which can be positioned in an operational position relative to the tube and relative to the solenoid so that it provides a magnetic path between the solenoid and portions of the tube. The yoke engages the tube and thereby prevents removal of the solenoid from tube. The invention thereby provides a very simple valve design with a low amount of components. The invention further provides a method of making a valve including fixing a solenoid to a tube by use of a yoke which engages the tube.

Abstract: Servo valve with a main piston (5) and a servo piston (13). The servo piston controls a pressure in a servo chamber and thereby controls movement of the main piston based on a pressure difference between two chambers of the valve. To facilitate opening of the valve by relatively small pressures even in high pressure systems, the servo chamber (7) according to the invention is provided inside the armature (11).
