Abstract
A gas spring shock absorber (10) includes a damping fluid cylinder (14) telescopically housed within a gas cylinder (12). A shaft (16) connects a sealed, outer end (18) of the gas cylinder (12) with a vented piston (32) movably mounted within damping fluid cylinder (14). Shaft (16) passes through a sealed inner end (28) of damping fluid cylinder (14) so that a sliding seal (34) located between gas cylinder (12) and damping fluid cylinder (14) creates a sealed variable-volume gas cylinder (40) between the cylinders.
