Abstract
An electromagnetic actuator 10 includes housing structure 12, first and second electromagnets 14 and 16 disposed in spaced relation in the housing structure, an armature 24 mounted for reciprocal movement between the electromagnets, and a spring assembly 11 operatively associated with the armature 24. The spring assembly includes a coil spring 30, a spring retainer 32 carrying the coil spring and being constructed and arranged to contact the armature 24, a spring adjusting member 38 engaged with a bore in the housing structure 12 and engaging the spring 30 so as to control compression of the spring associated with a set position of the armature 24 between the electromagnets. At least one cap screw 50 extends from a surface of the housing structure generally adjacent to the bore. A locking member 56 is engaged with the spring adjusting member 38 and with the cap screw 50. The cap screw 50 pushes against the locking member 56 to prevent movement of the spring adjusting member 38 to maintain the compression of the spring 30 associated with the set position of the armature 24.
