ABSTRACT:
An electromagnetic fuel injector has an axially fixed guide pin for axial alignment of a spring biased, movable armature. The guide pin has an abutment shoulder thereon for engagement with a surface of the armature whereby to serve as an abutment stop so as to establish a predetermined minimum working air gap between the opposed working surfaces of the armature and an associated solenoid pole. A spring seat ring carried by an axially movable adjusting rod slidably received by a portion of the guide pin serves as an abutment for one end of the armature spring. An externally accessible abutment screw is used to effect axial displacement of the adjusting rod and therefor of the spring seat ring whereby to adjust the force of the armature spring.
