Abstract
A shock absorber includes a two stage valve assembly that has two valve discs. The second valve disc defines the first stage at lower valve pressures and the first valve disc defines the second stage at higher valve pressures. The two valve discs can be defined by a single piece component or they can be separate components. The second valve disc can permit fluid flow by deflection of the second valve disc or by movement of the entire second valve disc. The two stage valve assembly can be incorporated into the piston assembly of the shock absorber and/or the two stage valve assembly can be incorporated into a base valve assembly.
