Patent ID: 8690118

Claim:
A solenoid actuated device comprising: an actuator body including a first body piece having a first clamping surface, a second body piece having a second clamping surface, and a clamping mechanism which includes a release state and a clamping state; a single-pole solenoid actuator assembly positioned at least partially within the actuator body and including a stator, an armature movable relative to the stator, and a movable pin coupled with the armature; the single-pole solenoid actuator assembly further including a one-piece compound armature housing defining a longitudinal axis and including an outer radial surface and an inner radial surface defining a guide bore for the movable pin, the compound armature housing having a load carrying component clamped between the first clamping surface and the second clamping surface, and a flux carrying component supported by the load carrying component and defining a sliding air gap with the armature, the load carrying component having a high structural strength and a low flux permeability, and the flux carrying component having a low structural strength and a high flux permeability, wherein the compound armature housing has a stepped configuration defining a first axial segment which includes the flux carrying component and the load carrying component, and a second axial segment which includes the guide bore; and a spacer positioned axially between the first axial segment of the compound armature housing and the second body piece, wherein the first clamping surface contacts the first axial segment of the compound armature housing and the second clamping surface contacts the spacer.
