Abstract

A suspension damping system for damping a sprung mass, the system including: at least one elastic support member coupled to the sprung mass; a first damping chamber containing hydraulic fluid; a reservoir chamber for hydraulic fluid urged from the first damping chamber; a piston assembly which extends into the damping chamber during a compression stroke and applies work on the hydraulic fluid as a compressive damping force; at least one compression damping valve which when open provides fluid communication between the first damping chamber and the reservoir chamber, said valve coupled to the at least one elastic support member; wherein, in use, the valve operates in accordance with the displacement of the elastic support member relative to the sprung mass.
