Abstract

Die Erfindung betrifft ein gasdruckladendes Selbstladegewehr, mit einem Gaszylinder (15), der am einen Ende durch einen Boden (17) abgeschlossen ist und eine Gaskammer (33) umschließt, die durch einen Gaskanal (35) an einem Anzapfungspunkt (5) mit der Laufbohrung (7) verbunden ist, und mit einem Gaskolben (25), der im anderen Ende des Gaszylinders (15) zwischen einer Ruhelage, in welcher er das kleinste Volumen der Gaskammer (33) festlegt, und einer Endlage, in welcher er das größte Volumen der Gaskammer (33) festlegt, verschieblich angeordnet ist.
Erfindungsgemäß ist der Gaskolben (25) im Gaszylinder (15) mit Spiel angeordnet; in der Außenumfangsfläche des Gaskolbens (25) sitzt mindestens ein Kolbenring (31), der sich gegen die Innenumfangsfläche des Gaszylinders (15) anlegt.
Beim Schuß dichtet der Kolbenring (31) nach außen ab und schabt gleichzeitig bei der Bewegung des Gaskolbens (25) den Pulverschmauch von der Zylinderwand, so daß diese stets sauber bleibt und die Bewegung des Gaskolbens (25) auch dann unbehindert erfolgen kann, wenn das Gewehr lange Zeit intensiv benutzt wird, ohne gereingt oder geölt zu werden.
