ABSTRACT:
An electromagnetic fuel injector has an axially adjustable nozzle assembly which provides an annular valve seat cooperating with a movable armature/valve member having at one end thereof a semi-spherical valve element and having at its opposite end a ball guide socket therein. A semispherical guide and stop member is positioned to be slidably received in the ball guide socket to guide the armature/valve member during reciprocation thereof and it is also used to provide a stop for the armature/valve member in the direction of its travel toward an associate pole piece so as to provide a fixed minimum air gap between the opposed working faces of these elements.
