Floating port blocker

The present invention relates generally to automotive dampers or shock absorbers which receive mechanical shock. More particularly, the present invention relates to a unique hydraulic valve assembly which allows greater tunability of the shock absorber in both the mode of low speed or low hydraulic fluid flow and the mode of high speed or high hydraulic fluid flow. 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.
