Abstract
A semi-active vehicle suspension system employing a shock absorber whose damping characteristics are variable under the control of a signal representing one or more conditions of the vehicle. The system employs a coaxially arranged valve pair to provide one or two fluid flow paths between a chamber of the shock absorber and a reservoir. Two of such coaxial valve pairs may be used in tandem to control both chambers of the shock absorber in an inverse relationship. Both of the tandem pairs may be controlled by a single spool which is controlled by a single control signal.
