Abstract

Official abstract text for this publication.

A method and apparatus for a vehicle suspension system gas spring. In one embodiment, a vehicle suspension system gas spring includes a compressible main gas chamber and an additional volume combinable with the main chamber to change a gas spring rate of the system. In one embodiment, a low friction piston seal is created by a flexible seal member.

First claim

Opening claim text (preview).

The invention claimed is: 1. A vehicle suspension system gas spring, comprising: a compressible main gas chamber; an additional gas volume, a gas pressure therein selectively combinable with or fully isolated from communication with, the compressible main gas chamber during a compression stroke to change a compressible gas volume of the system; a valve having a valve gas chamber and a bore therethrough; and an axially movable piston disposed in the bore of the valve, the pis…
