ABSTRACT:
A gas cylinder with internal time delay which is entirely self contained within the cylinder. A valve pin that controls communication between the two sides of the piston through one or more a one-way valves in the piston. As each piston is moved by a die into the cylinder body, it exposes a portion of reduced cross section on a valve pin and gas flows through a one way valve such that the effective area of the piston is reduced. When the die moves away from the workpiece, a time delay occurs and the piston is delayed until the piston moves upwardly and closes communication between the sides of the piston.
