ABSTRACT:
An air spring has a variable interior space at a gas pressure for spring action between relatively-vibrating bodies. A control device has a sensor electrically responsive to the gas pressure for electrically operating an intake valve for admitting gas to the interior space and an outlet valve for venting gas from the interior space to atmosphere. This damps or isolates vibrations in the air spring in dependence on the control device. The control device may also respond to auxiliary transducers for the gas pressure, spring height, and level, speed, steering, braking, or acceleration of a vehicle on which the air spring is used, for example.
