Abstract
An electromagnetic solenoid is adapted to open and close an associated valve or to reciprocally engage a slideable member. The solenoid includes an electromagnetic and multi-piece armature enclosed within a protective housing. The armature comprises an inner pole piece operatively connected to an outer pole piece to initially provide a multi-level air gap with respect to the electromagnet. The inner pole piece is telescopically received within the outer pole piece and may over-travel the outer pole piece once the motion of the outer pole piece has ceased.
