Estimating the term…
The present application relates to crushable body in the form of a corrugated thin walled tube e.g. for use in a piston assembly for engaging two selectively engageable parts. The piston assembly has a housing defining a piston cylinder and a piston. The assembly also has a piston stroke limiter. The piston stroke limiter is configured to limit the length of a return stroke of the piston from an extended stroke position and a retracted stroke position. A crushable body in the form of a corrugated thin walled tube acts between the piston and the piston stroke limiter and is arranged to reduce in axial length when a length of an extended stroke exceeds a length of a retraction stroke to maintain the length of the return stroke.
A crushable body for use in a position adjustment assembly, the crushable body comprising a thin-walled tube comprising a corrugated crushable body portion, formed with corrugations along its length, between two flat end portions, the corrugated crushable body portion configured to form a crushed body of reduced axial length compared to the axial length of the tube when a predetermined force is applied to the tube.
