ABSTRACT:
A collision between members is prevented as a movable part moves. A guide member is disposed along a diaphragm which supports a valve element. The guide member have a curved surface which the diaphragm, whereby a region of the guide member where it abuts against the diaphragm shifts. By shifting the fulcrum for the diaphragm, an operating response is achieved which stops the movement of the valve element before a gap between it and a core of magnetizable material reduced to zero as the valve element is attracted by the core. To define a positive change in the position of the fulcrum, the guide member is formed of a metallic material. The guide member is formed with openings to reduce its rigidity.
