ABSTRACT:
An impact absorbing strut or shock absorber is disclosed comprising at least two telescoping tubes defining a damping fluid chamber. A quantity of damping fluid partially fills the chamber and a quantity of compressible gas fills the remainder of the chamber. The compressible gas absorbs small loads imposed upon the shock absorber. A fluid throttling port communicates with the chamber and a blowout plug is normally disposed in the fluid throttling port. When the shock absorber is heavily loaded the plug is ejected from the port to allow the damping fluid to be throttled through the port. A frangible polymeric encasement surrounds the shock absorber and seals the damping fluid and compressible gas therein. Relative movement between the encasement and one of the telescoping tubes is provided to absorb small deflections of the shock absorber without rupturing the encasement.
