Abstract
An automatic damper for an automobile automatic damper system which provides a compression valve operable to vary compressive damping characteristics of a damper, as well as a rebound valve operable to vary rebound damping characteristics of the damper. Use of the invention in cooperation with presently available electronic control modules and sensing algorithms provides a damper with either discrete valves or continuously variable valves for independently setting the rebound and compression damping characteristics of the damper.
