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 first pole member associated with the electrically energizable winding, and an armature movable with respect to the first pole member in a linear direction. The armature occupies a first position relative to the first pole member when the winding is not electrically energized and a second position relative to the first pole member when the winding is electrically energized. The actuator has a second pole member which is movable with respect to the first pole member in the linear direction so as to form an air gap of variable width between the first and second pole members to change the magnetic characteristics of the solenoid actuator, and thus the response of the actuator. The second pole member is movable to a position relative to the first pole member in which the second pole member is spaced from the first pole member, and biasing means are provided for maintaining the relative position of the first and second pole members. The biasing means may be provided as a spring for urging the second pole member towards the first pole member and adjustable stop means, such as a screw, disposed in contact with the second pole member.
