Abstract

A shock absorber includes a piston assembly having a compression valve assembly and a rebound valve assembly. One of the valve assemblies includes a free floating port blocker disc disposed in a pressure chamber. The blocker disc allows for the low speed bleed flow of fluid in one direction but restricts the low speed bleed flow of fluid in the opposite direction.
