Abstract
An electromagnetic actuator having a unitary pole piece arranged within and coupled to a housing is provided. The housing is coupled to the unitary pole piece such that a load on the unitary pole piece is reduced during assembly and/or installation of the electromagnetic actuator. The unitary pole piece is structured to reduce leakage past an armature slidably received within the pole piece.

An electromagnetic actuator comprising:
- a housing;
- a unitary pole piece at least partially arranged within the housing, the unitary pole piece including a first end, a side wall defining a choke portion, and a mounting surface extending from a distal end of the side wall, wherein the first end and the side wall define an armature recess;
- an end cap arranged around the unitary pole piece adjacent to the first end;
- an armature slidably received with the armature recess of the unitary pole piece;
- and
- a wire coil arranged within the housing and positioned around the armature.
