Abstract
An air spring suspension damper assembly includes a first housing and a second housing which telescope relative to each other. An actuating member such as a cable is connected to a height leveling valve contained in one of the housings and attached to the other housing. The actuating member moves a member such as a rotating cam, a rotating valve plate and/or a rotating valve such that changes in the suspension height rotate the member. Rotation of the member selectively opens inlet and exhaust flow paths to control the air pressure in the damper assembly and maintain air suspension height at a predetermined height.
