Abstract
A drive for a breech/breech carrier renders it axially adjustable relative to a weapon barrel. The drive includes a motor, two engaging cams mounted on a chain arranged below the breech and guided around two sprocket wheels. A slide is mounted in a guide at the bottom of the breech/breech carrier so as to move at a right angle to the direction of fire, with a groove extending over its entire width. The respective engaging cam entrains the breech in forward motion relative to the direction of fire, or in reverse motion, once the shot is fired, and transports the breech forwards, is displaced from the groove, and moves backwards without the breech, thereby allowing breech rest periods in a forward position. During firing, the slide moves, whereas it remains stationary when no shot is fired so no further engaging cam can entrain the breech backwards.
