Hydro-damped air spring

The air spring (1) of the invention combines both traditional air spring characteristics and components with internal hydro damping. The air spring has an upper retainer (2), a piston (4), an elastomeric sleeve (6) secured to the upper retainer (2) at a first end (10) and secured to the piston (4) at the lower end (12), and a damping device (8). The damping device (8) has an upper (50) and a lower (52) variable volume chamber and a channel (54) connecting the two variable volume chambers, and a damping fluid contained within the damping device.
