Abstract

A piston and cylinder type damper is provided having a cylinder (12) with a piston assembly (10) which is mounted for reciprocal linear movement therein. The piston assembly (10) divides the cylinder (12) into separate chambers with a restricted flow path extending therebetween for passage of damping fluid contained within it. A piston rod (11) is mounted for linear reciprocal movement with respect to the cylinder (12) and is arranged to engage the piston assembly (10) with abutting contact. The contact between the piston rod (11) and piston assembly (10) is arranged to be remote from the restricted flow path.
