Abstract
A shock absorber having a pair of valve assemblies which include an acceleration sensitive valve which couples the working chamber of the shock absorber to the shock absorber's reservoir chamber through a fluid path to provide a soft damping characteristic for the shock when the shock absorber experiences acceleration beyond a specific amount. A compression valve assembly and a rebound valve assembly are also provided which controls the fluid flow through the piston and the base assembly, respectively, to provide a firm damping characteristic for the shock absorber during low acceleration movement.
