Abstract
Dispositif entraîné par les gaz pour la charge d'un projectile dans un fusil mitrailleur automatique et mécanique de support du canon et de l'extrémité avant. La pression des gaz dégagés par le tir du projectile est transmise au bloc de culasse par un mouvement de glissement axial d'une barre 7,8 montée à l'extérieur du canon ou du tube magasin de cartouches 6 de façon à déverrouiller le bloc de culasse 3. Le dispositif comprend en outre un ressort de réglage 9 pour arrêter l'écart entre les deux parties 7 et 8 de la barre, un cylindre 10 fixé au canon dans lequel sont introduits les gaz, l'extrémité avant de la barre d'actionnement entrant dans le cylindre tandis que son extrémité arrière passe à travers un trou de guidage du récepteur de façon à ce qu'elle vienne heurter la surface avant 3a du bloc de culasse, cette extrémité arrière étant munie d'une butée pour limiter le mouvement axial de la barre d'actionnement. Le mécanisme de support du canon et de l'extrémité avant sert à arrêter simultanément la rotation du canon et de l'extrémité avant.
