Abstract
A seal is proposed between the drum (2) having a plurality of cartridge chambers (3) and a weapon barrel (1) of a drum cannon, wherein the seal comprises at least one elastically pretensioned obturation ring (4). Each cartridge chamber (3) has an obturation ring (4) for drum-side integration, while one obturation ring (4) suffices for barrel-side integration. The obturation is integrated between the two and is pressed against the face (9) of the weapon barrel (1) or the face of the cartridge chamber (3) that is aligned with the bore axis of the weapon barrel (1) such that immediate sealing occurs even at low gas pressures.
