Abstract
A strut includes a shock absorber and an air spring. The air spring is positioned around and concentric with the shock absorber. A sealing system is employed which seals the pressurized air chamber of the air spring. The sealing system utilizes an elastomeric seal located between the air spring and the shock absorber. The elastomeric seal can be a rectangular annular seal, an O-ring seal or an elastomeric seal bonded to a metal plate.
