Zusammenfassung: | A piston assembly for engaging two selectively engageable parts comprising: a housing defining a piston cylinder; a piston; and an adjuster assembly comprising: a piston stroke limiter configured to limit the length of a return stroke of the piston from an extended stroke position and a retracted stroke position, the piston stroke limiter comprising a spring and a spring guide; and an inner crushable tube, acting between the piston and the piston stroke limiter, the inner crushable tube being arranged to reduce in axial length when a length of an extension stroke exceeds a length of a retraction stroke to maintain the length of the return stroke; wherein the inner crushable tube comprises an inner crushable thin-walled tube surrounding at least a portion of the piston. |
