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 nut is threaded onto external threads provided on the guide pin to serve as an abutment for one end of the armature spring. This nut is provided with non-circular conformations extending radially outward thereof which are slidably received in axially orientated slots in the solenoid pole to prevent rotation of the nut relative thereto. The guide pin is provided with an externally accessible driver-receiving head whereby it can be rotated to effect axial displacement of the spring seat nut whereby to adjust the force of the armature spring.
