ABSTRACT:
A self-actuating vibration damper for use in a pneumatic suspension system of a motor vehicle having an air spring that defines an air chamber is disclosed. Located within the air chamber is an actuator rod mounted between two air valves. Upon application of a sufficiently heavy load to the vibration damper, a first end of the actuator rod closes the first air valve to prevent release of air from the air chamber to the outside atmosphere, and a second end of the actuator rod opens the second valve to admit compressed air into the air chamber.
