Abstract

A shock absorber having a casing and a piston with a piston head mounted thereon and located in a chamber within the casing containing fluid, an annular peripheral groove on the shock absorber head for mounting an annular turbulence inducing member having an L-shaped cross section which is slidable on the bottom surface of the groove from a passive position which it occupies when the piston head forces liquid from one side thereof to the other in a fluid amplification mode and which moves to an active position for creating turbulence within the groove during the rebound movement of the piston head.
