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.The invention relates to a gas pressure loading self-loading rifle, with a gas cylinder (15) through at one end a floor (17) is closed and a gas chamber (33) encloses by a gas channel (35) at a tap point (5) is connected to the bore (7), and with a gas piston (25) in the other end of the gas cylinder (15) between a rest position, in which he sets the smallest volume of the gas chamber (33), and one End position in which it has the largest volume of the gas chamber (33) specifies is slidably arranged.

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.According to the invention, the gas piston (25) is in the gas cylinder (15) arranged with game; in the outer peripheral surface of the gas piston (25) sits at least one piston ring (31), which is against the inner circumferential surface of the gas cylinder (15).

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.

Figure 00000001
When firing, the piston ring (31) seals from the outside and at the same time scrapes the powder smoke off the cylinder wall during the movement of the gas piston (25), so that this always remains clean and the movement of the gas piston (25) can also take place without hindrance if that Rifle is used intensively for a long time without being cleaned or oiled.
