Abstract
The air spring of the present invention combines both traditional air spring characteristics and components with internal hydro damping. The air spring has an upper retainer, a piston, an elastomeric sleeve secured to the upper retainer at a first end and secured to the piston at the lower end, and a damping device. The damping device has an upper and a lower variable volume chamber and a channel connecting the two variable volume chambers, and a damping fluid contained within the damping device.
