METHODS AND APPARATUS FOR COMBINED VARIABLE DAMPING AND VARIABLE SPRING RATE SUSPENSION

摘要

Pressure-sensitive vales are incorporated within a dampening system to permit user-adjustable tuning of a shock absorber. In one embodiment, a pressure-sensitive valve includes an isolated gas chamber having a pressure therein that is settable by a user.
