The assembly further includes a tapered center shaft disposed at least partially within the bore of the housing. The chamber includes an angled contact surface, a sliding wedge, and a load spring. The sliding wedge is positioned to apply a force onto the angled contact surface of the chamber. The sliding wedge is also positioned to apply a frictional force to a rod portion of the tapered center shaft. The load spring is compressed between a contact surface of the chamber and a contact surface of the sliding wedge. The load spring is positioned to apply a compressive force onto the contact surface of sliding wedge toward the angled contact surface of the chamber.
