Abstract

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 a crushable body, acting between the piston and the piston stroke limiter, the crushable body 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 crushable body comprises an inner crushable thin-walled tube (60) surrounding at least a portion of the piston and an outer crushable thin-walled tube mounted (80) around and radially outwards of the inner crushable tube, an end (81) of the outer crushable tube connected to an end (63) of the inner crushable tube, the thin-walled tubes configured to form a crushed body of reduced axial length compared to the axial length of the thin-walled tube when a predetermined force is applied to the thin-walled tube
