Abstract

Bei einer als Gasdrucklader ausgebildeten automati­ schen Feuerwaffe mit einem über eine Bohrung mit dem Rohr der Waffe verbundenen Zylinder, in dem ein auf den Verschluß wirkender Kolben verschiebbar gelagert ist, und mit einem in der Verbindung zwischen Rohr und Gaszylinder angeordneten, automatisch wirkenden Absperrventil zur Regelung der Gaszufuhr, wird eine vom Geschoß weitge­ hend unabhängige Ausführung des Ladevorganges dadurch bewirkt, daß die Waffe ein lafettiertes System (1) aufweist, das beim Abfeuern eines Schusses eine vom Schußimpuls abhängige Rücklaufbewegung ausführt, und daß die Stel­ lung des Absperrventils (44) von einer in Bezug auf das lafettierte System (1) beweglich gelagerten und von einer Feder (45) belasteten, trägen Masse gesteuert wird, derart, daß infolge der Abstimmung der Größe der Masse und der Kraft der Feder auf das Rücklaufverhalten des lafettierten Systems die Masse nur einer langsamen Rücklaufbewegung dieses Systems, wie sie beim Verschießen von Munition mit schwachem Geschoßimpuls stattfindet, folgen und dabei das Ventil offenhalten kann, wogegen die Masse gegenüber dem System zurückbleibt und umso mehr ein Abschließen der Bohrung bewirkt, je schneller bei starkem Geschoßim­ puls die Rücklaufbewegung des Systems erfolgt. Vorzugs­ weise wird das Absperrventil von einem im Zylinder (31) angeordneten Schieber (44) gebildet, der auch unmittelbar die die Ventilstellung bestimmende und von einer Feder belastete, träge Masse bildet. In an automatic designed as a gas pressure loader firearm with a bore through the Pipe of the weapon connected cylinder, in which one on the Closure acting piston is slidably mounted, and with one in the connection between pipe and gas cylinder arranged, automatically acting shut-off valve for Regulation of the gas supply, one is from the floor independent execution of the charging process causes the weapon to have a mounted system (1), the one firing a shot is one of the shot impulse dependent return movement, and that the stel tion of the shut-off valve (44) in relation to the Mounted system (1) movably supported by one Spring (45) loaded, inert mass is controlled, such that due to the coordination of the size of the mass and the Force of the spring on the return behavior of the carriage Systems the mass of only a slow return movement this system, like when using ammunition weak bullet impulse takes place, and follow the valve can keep open, whereas the mass opposite remains in the system and even more a lock the bore causes the faster the bullet is strong pulse the return movement of the system takes place. Preferential the shut-off valve is operated by a cylinder (31) arranged slide (44) formed, which is also immediate the valve position determining and by a spring burdened, inert mass forms.
