Vehicle supension damper with integral height leveling valve

摘要

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 is 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 suspension height rotate the member. Rotation of the member selectively opens inlet and exhaust flow paths to control air pressure in the damper assembly and to maintain air suspension height at a predetermined height.
