Abstract

In a sporting air gun in the nature of a recoilless pressurized-air weapon, having a recoilable system which is translatably mounted so as to slide forward and backward on the gunstock of the weapon in a direction which is generally longitudinal. The recoil system compensates by opposed motion the impulse from the firing of the weapon arising from the impulse of each projectile, from the propellant gas, and from individual components which are accelerated for the purpose of the firing. The system minimally comprises a breech casing to which a barrel, a firing mechanism, other functional parts of the weapon, or added masses may be attached to increase the weight of the system. The system has a center of mass lying off the line of action of the impulse resulting from the firing, whereby a torsional impulse is superposed on the firing-resultant impulse. The improvement in the air gun includes at least one torsional impulse generator which is positioned in or on the weapon. This generator forms an autonomous functioning unit with other parts of the weapon, whereby the torsional impulse resulting from the generator is simultaneous with and directed opposite to the torsional impulse which is induced by the recoil system in the firing phase of operation, whereby the torsional impulse from the generator acts substantially in the same plane as or substantially in a parallel plane to the torsional impulse from the recoilable system.
