Abstract
The present invention relates to gas cylinder springs and, more particularly, to gas cylinder springs which receive gas from a manifold into which the gas cylinders are threaded. The invention specifically relates to a way of automatically and in a nonmechanical manner expel atmospheric pressure from the gas spring. The piston rod of the gas spring is tapered slightly to provide a pocket into which atmospheric pressure can collect and be expelled around the gas spring seals on each stroke of the piston rod.
