ABSTRACT:
A solenoid actuator including a coil of electrically conductive wire having a central opening, a yoke of magnetic material permanently surrounding the coil, and a stationary armature permanently secured to the yoke and projecting from the yoke into the central opening in the coil. A core tube of non-magnetic material is removably retained within the central opening in the coil, the core tube having a closed end engaging the stationary armature and the core tube being separable from the coil-yoke-armature assembly. A movable armature within the core tube is slidable toward and away from the stationary armature. A stationary armature extension of magnetic material surrounds the exterior of the core tube, the extensions being an element independent of the stationary armature. The extension may be an annular element, coaxial with the core tube, which engages the stationary armature. The extension may be a ring having a wall of uniform or non-uniform thickness along its length. Stationary armature extensions of different lengths are used, depending upon the size of the air gap between the movable armature and the stationary armature when the solenoid coil is deenergized.
