Abstract
A barreled weapon with regenerative propellant injection through the intermediary of at least one axially displaceable piston. A ring-shaped or annular cylindrical space is arranged coaxially about the weapon barrel, in effect, about the projectile or shell chamber, in which space there are arranged two mutually oppositely located, opposingly movable annular or ring pistons, whose piston shafts presently divide the space which is available behind the piston head into two selectively interconnectable loading chambers, each piston head possessing passageways which extend from the loading chambers and connect into the end surfaces of the piston heads, which are arranged offset relative to each other in such a manner so as to mutually seal off upon contacting of the oppositely located end surfaces of the piston heads.
