DIFFERENTIAL PRESSURE PISTON-COMBUSTION CHAMBER FOR BARRELED WEAPONS

Abstract

A differential pressure piston-combustion chamber system for barreled or tube-firing weapons or guns with a regeneratively-actuated propellant injection device for the generation of propellant gases of liquid, in particular hypergolic propellant components. A differential pressure piston is arranged so as to be axially movably in the weapon housing coaxially relative to the weapon barrel, with the piston incorporating propellant infeed passageways as well as a loading piston which is in communication with filling passageways. In the cylindrical shaft of the differential pressure piston, there is concentrically arranged a charging piston which is movably axially relative thereto, where the free end is in communication with infeed passageways, and the differential pressure piston and the charging piston are provided with control rolls which, respectively, roll along as associated control cam track on a drum controller. Hereby, the drum controller, which is driven through an external gearing system, can be rotatably supported in concentricity with the charging piston in the weapon housing. Alternatively, the drum controller can be rotatably supported eccentrically relative to the differential pressure piston and the charging piston in the weapon housing.
