| 摘要 | A gun is provided with an automatic device intended partly for retardation of a cartridge during the latter portion of its ramming cycle into the chamber, partly for blocking/locking of the cartridge in the chamber, partly for exposure of the spent cartridge case after firing and partly for ejection of the spent case after firing. The device includes impact means (4, 5, 6) which, on ramming of the ammunition unit, enter into interaction with and retard the ammunition unit. Also included is a pressure accumulator (15) which is chargeable via the impact means with existing kinetic energy in the ammunition unit. The breech (8) is closed by means of energy stored in the pressure accumulator. During its activation with the aid of the stored energy the breech enters into interaction with the case and retains this during firing and during a predetermined portion of the rearward-directed motion in the gun occurring on account of firing. | ||||||
