Abstract
A shock absorber has a base valve assembly which includes a compression valve assembly and an acceleration valve assembly. The compression valve assembly controls a fluid path through the base assembly to provide a firm damping characteristic for the shock absorber during low acceleration movement. The acceleration valve assembly controls a second fluid path through the base assembly to provide a soft damping characteristic for the shock when the shock absorber experiences acceleration beyond a specified amount.
