ABSTRACT:
A pressure limiting propellant actuating system includes an outer barrel housing having a combustion chamber formed therein. A main piston is movable in the barrel housing when a pressure is developed in the combustion chamber. A relief piston is concentrically mounted and fixedly movable with the main piston when the gas pressure is exerted thereon from the combustion chamber. The relief piston includes a separation mechanism for limiting the output force and simultaneously, maintaining output pressure from the combustion chamber.
