ABSTRACT:
A device performs forwardly oriented case ejection from an externally driven automatic cannon, the cannon having a chamber, a breechblock which is longitudinally movable along a path by the action of a rotating control cylinder and which simultaneously advances an ejecting device for ejecting a cartridge case, and an intermittently rotating rotor having a plurality of rotor pockets disposed circumferentially thereabout for moving a cartridge into the path of the breechblock and for removing a cartridge case from the path of the breechblock, wherein the ejecting device is a case pusher for ejecting empty cartridge cases, the case pusher being coaxially mounted within the rotor for longitudinal movement relative thereto, the case pusher including a plurality of carrier elements projecting radially into respective ones of the rotor pockets; and a connecting arrangement is used for joining the case pusher with the breechblock such that the case pusher is axially displaceable together with the breechblock and the case pusher intermittently rotates with the rotor.
