Abstract
A solenoid actuator, adapted for use in an electronic control valve for a fuel injector, having an electrically-energizable electromagnetic device, such as a winding, a pole member associated with the electrically energizable winding, and an armature movable with respect to the pole member. The armature occupies a first position relative to the pole member when the winding is not electrically energized and a second position relative to the pole member when the winding is electrically energized. The actuator has an adjustment screw which is movable with respect to the pole member to form an air gap of variable width internal to the pole member to change the magnetic characteristics of the solenoid actuator, and thus the response of the actuator.
