Recoil free firing device for projectiles

摘要

The invention concerns a firing device for a kind of weapon where absence of recoil is achieved via an entity being shot backwards from a barrel (1), at the same time as a projectile is fired in the forward direction. The device involves a projectile (3), the acceleration sections of which have been elongated in comparison with conventional devices via the overlapping of the sections across each other and a counterweight container (5). The rear end of the projectile is designed with an open pipe (4) at the back, which is equipped with a bottom, with an outer diameter which allows it to run in the barrel (1). The counterweight holder (5) is designed as a piston which can run in the piston pipe (4). A propelling charge (6) is placed between the pipes bottom and the container whose propellant gas on firing accelerates the components in opposite directions.
