Abstract
The air spring is comprised of a flexible airsleeve, a retainer, and a main piston. The airsleeve is secured at one end by the retainer and at the opposing end by the main piston. A hollow restraining piston extends from the retainer and into the main piston. The restraining piston acts as a lateral stabilizer, over extension restraint and height control. The hollow region in the restraining piston communicates through at least one passage with an air chamber formed between the airsleeve and the outer surfaces of the restraining piston and the main piston. Fluid is admitted to or exhausted from the air spring through a valve which functions relative to the displacement of the restraining piston and the main piston.
