Rigid in tension locking gas springs have oil on both sides of the piston so that the chamber between (where the rod enters the body) and the piston are always full of oil. This oil is contained by a floating piston that separates it from the gas in the enclosed tube. Since oil is incompressible, when a tension load is applied to the locked rod the oil between the nose bearing and the piston does not compress and the rod cannot move. Applications for rigid in tension locking springs include hospital beds, aircrafts, coach and rail seat back recline control and wheel chair recline and support systems.
