ABSTRACT:
An adjustable damping shock absorber includes a pressure tube with a piston valve assembly slidably disposed within it. The piston valve assembly includes a compression valve assembly which is biased to a closed position and an extension valve assembly which is also biased to a closed position. The damping rate for the shock absorber is adjusted by selectively changing the biasing load of one or both of the valve assemblies. When the biasing load is increased, a firm damping for the shock absorber is produced. When the biasing load is decreased, a soft damping for the shock absorber is produced.
