초록

A compressed gas weapon (10) is configured in the breech portion (18) of its barrel (12) to accommodate a projectile (24) in a position of readiness to fire and to reproducibly caliber the projectile (24) in the process of conveying it into the position of readiness to fire.

A compressed gas weapon system comprising a firing mechanism having a bore with an axis and a projectile exit end and defined by at least one member, a projectile, a compressed gas generating cartridge usable for a single shot, said compressed gas generating cartridge containing a propellant for generating a compressed gas for providing a gas pressure for propelling the projectile axially of the bore in a direction of firing towards the projectile exit end and being provided in its interior with an expansion chamber for homogenizing the gas pressure, and a trigger mechanism adapted to cause the compressed gas generating cartridge to generate the compressed gas, said bore having, at an axial distance from the projectile exit end, an entrance for the projectile and the compressed gas generating cartridge, a cartridge-receiving chamber proximate to the entrance, and a projectile-receiving chamber adjacent an anterior end of the cartridge-receiving chamber with respect to the direction of firing, the chambers accommodating, in a position of readiness to fire of the compressed gas weapon system, the cartridge in a position behind the projectile with respect to the direction of firing of the projectile, the projectile having with respect to the direction of firing an anterior end, a nose portion adjacent the anterior end, a posterior end and an apron portion adjacent the posterior end, the apron portion of the projectile having a diameter that is greater than the diameter of the nose portion and greater than the diameter of a part of the projectile-receiving chamber that receives the apron portion when the projectile is received in the projectile-receiving chamber so that the diameter of the apron portion of the projectile is reduced to caliber the projectile, the posterior end of the projectile having a cavity, and the cartridge having at its anterior end with respect to the direction of firing a tapered projection, the cavity of the projectile and the tapered projection of the cartridge being, in the position of readiness to fire, in mutual abutment over at least a part of their axial lengths by respective conical surfaces of the cavity and the projection, the tapered projection of the cartridge having a gas exit orifice opening, in the position of readiness to fire, into the cavity of the projectile, and the cartridge being formed at least partly of plastic so as to be expandable and having an outside diameter so matched to an inside diameter of the cartridge-receiving chamber that the cartridge can be smoothly introduced into the cartridge-receiving chamber, and can, under the action of the gas pressure building up in the expansion chamber, expand into gas-tight contact with an inner peripheral surface of the cartridge-receiving chamber.
