Abstract
The invention provides a valve comprising a tube for guiding movement of a plunger, a solenoid 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.
