Abstract
Description
Die Erfindung betrifft eine Gasdrucksteuervorrichtung an einer Maschinenwaffe, deren Verschlußeinrichtung und/oder Munitionszuführeinrichtung durch den beim Schuß entstehenden Gasdruck betätigbar ist, wobei das Gas aus dem Waffenrohr über eine Düse in einem Gaskanal der Einrichtung zugeführt ist.The invention relates to a gas pressure control device on a machine gun, the breech and / or ammunition supply device can be actuated by the gas pressure generated during the shot, the gas being supplied from the weapon barrel via a nozzle in a gas channel to the device.
Übliche Maschinenwaffen weisen einen oder zwei Gaskanäle mit Gasdüsen gleichen Durchmessers zum Antrieb des Verschlusses der Waffe auf. Für den Antrieb der Munitionszuführeinrichtung ist meist eine Düse anderen Durchmessers vorgesehen. Über die Düsen betätigt das sich beim Schuß entwickelnde Druckgas den Verschluß bzw. die Munitionszuführeinrichtung. Die Düsen sind in das Waffenrohr oder in das Waffengehäuse eingebaut. Sollen sie ausgebaut werden, dann muß das Waffenrohr demontiert werden. Dies ist aufwendig.Conventional machine guns have one or two gas channels with gas nozzles of the same diameter for driving the weapon breech. A nozzle of a different diameter is usually provided for driving the ammunition supply device. The compressed gas developing during the shot actuates the breech or the ammunition feed device via the nozzles. The nozzles are built into the weapon barrel or into the weapon housing. If they are to be removed, the weapon barrel must be dismantled. This is expensive.
Sollen mit der Maschinenwaffe unterschiedliche Munitionsarten verschossen werden, dann ist damit verbunden, daß beim Schuß im Waffenrohr entsprechend unterschiedliche Gasdrücke auftreten. Da die Düsen auf einen speziellen Gasdruck ausgelegt sind, kann es zu Funktionsstörungen kommen, wenn im Waffenrohr ein anderer als der vorgesehene Gasdruck auftritt. Um die Funktionssicherheit zu gewährleisten, muß vor dem Verschuß einer anderen Munitionsart das Waffenrohr ausgebaut werden und es müssen dem Gasdruck der vorgesehenen Munitionsart entsprechende Düsen eingebaut werden. Dies verhindert einen schnellen Wechsel der zu verschießenden Munitionsart.If different types of ammunition are to be fired with the machine gun, the result is that correspondingly different gas pressures occur in the gun barrel when fired. Since the nozzles are designed for a special gas pressure, malfunctions can occur if a different gas pressure than the intended one appears in the weapon barrel. In order to ensure the functional safety, the weapon barrel must be removed before the firing of another type of ammunition and the gas pressure of the the appropriate type of ammunition appropriate nozzles are installed. This prevents a quick change of the type of ammunition to be fired.
Auch bei extremen Umweltbedingungen kann es erforderlich sein, andere Düsen einzusetzen, um die Waffenfunktion zu sichern.Even in extreme environmental conditions, it may be necessary to use other nozzles to ensure the weapon function.
Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art vorzuschlagen, die es auf einfache Weise, ohne daß das Waffenrohr ausgebaut werden muß, erlaubt, unterschiedliche Düsen wahlweise in den Gaskanal zu bringen.The object of the invention is to propose a device of the type mentioned at the outset, which allows different nozzles to be brought into the gas duct in a simple manner without the need to remove the weapon barrel.
Erfindungsgemäß ist obige Aufgabe bei einer Vorrichtung der eingangs genannten Art dadurch gelöst, daß in einem Düsenträger wenigstens zwei unterschiedliche Düsen angeordnet sind und daß der Düsenträger verstellbar gelagert ist, so daß in einer Stellung des Düsenträgers eine der Düsen und in einer weiteren Stellung des Düsenträgers eine andere der Düsen in dem Gaskanal liegt.According to the invention, the above object is achieved in a device of the type mentioned in the introduction in that at least two different nozzles are arranged in a nozzle holder and in that the nozzle holder is adjustably mounted, so that one of the nozzles in one position of the nozzle holder and one in a further position of the nozzle holder other of the nozzles is in the gas channel.
Durch ein Verstellen des Düsenträgers läßt sich damit in dem Gaskanal die in diesem wirksame Düse auswechseln. Sind mehrere Gaskanäle vorgesehen, dann läßt sich durch einen einzigen Verstellvorgang in jeden der Gaskanäle eine geeignete Düse bringen.By adjusting the nozzle holder, the effective nozzle in the gas channel can be exchanged. If several gas channels are provided, a suitable nozzle can be brought into each of the gas channels by a single adjustment process.
Das Verstellen des Düsenträgers kann von Hand erfolgen. Es ist auch möglich, die Verstellung fernzusteuern.The nozzle holder can be adjusted by hand. It is also possible to control the adjustment remotely.
Durch die Erfindung ist die Gasdrucksteuervorrichtung auf einfache Weise und schnell an die jeweilige Munitionsart oder an extreme Umweltbedingungen anpaßbar. Das Waffenrohr braucht hierfür nicht ausgebaut zu werden. Die vorgesehenen unterschiedlichen Düsen stehen in dem Düsenträger bereit.The gas pressure control device can be easily and quickly adapted to the respective type of ammunition or to extreme environmental conditions by means of the invention. The gun barrel does not need to be removed for this. The different nozzles provided are available in the nozzle holder.
Durch die Vorrichtung ist gewährleistet, daß bei unterschiedlichen Gasdrücken die Funktion der Verschlußeinrichtung bzw. der Munitionszuführeinrichtung gewährleistet ist. Denn durch Einschieben der betreffenden Düse in den betreffenden Gaskanal ist gewährleistet, daß die an den Gaskanal angeschlossene Verschlußeinrichtung bzw. Munitionszuführeinrichtung mit dem für die Funktion geeigneten, gegenüber dem Druck im Waffenrohr reduzierten Druck, beaufschlagt wird.The device ensures that the function of the closure device or the ammunition supply device is ensured at different gas pressures. By inserting the nozzle in question into the gas channel in question, it is ensured that the closure device or ammunition supply device connected to the gas channel is acted upon by the pressure which is suitable for the function and is reduced compared to the pressure in the weapon barrel.
Ein weiterer Vorteil der Erfindung besteht darin, daß durch das Einsetzen einer entsprechenden Düse in den Gaskanal die Kadenz der Waffe gesteuert werden kann.Another advantage of the invention is that the cadence of the weapon can be controlled by inserting an appropriate nozzle into the gas channel.
Eine zwangsweise Unterbrechung der Funktion der Waffe läßt sich dadurch erreichen, daß der Düsenträger so verstellbar ist, daß er den Gaskanal bzw. die Gaskanäle verschließt.A forced interruption of the function of the weapon can be achieved in that the nozzle holder is adjustable so that it closes the gas channel or channels.
Vorzugsweise ist der Düsenträger als das Waffenrohr umgreifender Ring ausgebildet, der um die Längsachse des Waffenrohrs drehbar ist. Damit lassen sich in dem Träger auf einfache Weise für mehrere am Umfang des Waffenrohrs angeordnete Gaskanäle jeweils mehrere Düsen vorsehen, wobei durch eine entsprechende Drehung des Düsenträgers die betreffende Düse in den Gaskanal gestellt wird.The nozzle carrier is preferably designed as a ring encompassing the weapon barrel, which is rotatable about the longitudinal axis of the weapon barrel. In this way, a plurality of nozzles can be provided in a simple manner in the carrier for a plurality of gas channels arranged on the circumference of the weapon barrel, the relevant nozzle being placed in the gas channel by a corresponding rotation of the nozzle carrier.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen und der folgenden Beschreibung eines Ausführungsbeispiels. In der Zeichnung zeigen:
- Figur 1 eine Teilansicht einer Maschinenwaffe im Schnitt längs der Linie I-I nach

- Figure 2 is a view along the line II-II of Figure 1.
An einem Waffengehäuse(1) ist ein Waffenrohr(2) angeordnet. In der Wandung des Waffenrohrs(2) verlaufen drei Gaskanäle(3). In Figur 1 ist nur einer der Gaskanäle(3) zu sehen. Die Gaskanäle(3) münden an ihrem einen Ende ins Innere des Waffenrohrs(2). An ihrem anderen Ende stehen sie Gaskanälen(4) gegenüber, die im Waffengehäuse(1) angeordnet sind. In der Wandung des Waffenrohrs(2) sitzt am anderen Ende jedes Gaskanals(3) eine Dichtdüse(5).A weapon barrel (2) is arranged on a weapon housing (1). Three gas channels (3) run in the wall of the weapon barrel (2). In Figure 1, only one of the gas channels (3) can be seen. The gas channels (3) open at one end into the inside of the gun barrel (2). At their other end they face gas channels (4) which are arranged in the weapon housing (1). A sealing nozzle (5) is located in the wall of the weapon barrel (2) at the other end of each gas channel (3).
Das Waffenrohr(2) ist an seinem Umfang von einem ringförmigen Düsenträger(6) umgriffen. Dieser ist um die Längsachse des Waffenrohrs(2) drehbar. Er liegt axial zwischen einer Stirnfläche(7) des Waffengehäuses(1), an der die Gaskanäle(4) enden und den Dichtdüsen(5) des Waffenrohrs(2).The circumference of the weapon barrel (2) is encompassed by an annular nozzle carrier (6). This can be rotated around the longitudinal axis of the weapon barrel (2). It lies axially between an end face (7) of the weapon housing (1) at which the gas channels (4) end and the sealing nozzles (5) of the weapon barrel (2).
Im Düsenträger(6) ist für jeden der drei Gaskanäle(3 bzw 4) ein Paar von Düsen(8,9) angeordnet. Die Düsen(8,9) weisen unterschiedliche freie Querschnitte auf. Sie sind in entsprechende Bohrungen(10) des Düsenträgers(6) eingesetzt.A pair of nozzles (8, 9) is arranged in the nozzle carrier (6) for each of the three gas channels (3 or 4). The nozzles (8, 9) have different free cross sections. They are inserted into corresponding holes (10) in the nozzle holder (6).
Im Düsenträger(6) ist ein Raststift(11) radial verschieblich gelagert, der durch eine Druckfeder(12) belastet ist. Am Waffenrohr(2) sind drei dem Raststift(11) zugeordnete Rastkerben(13) ausgebildet. Außerdem ist am Düsenträger(6) ein Griffglied(14) befestigt.A locking pin (11) is radially displaceably mounted in the nozzle carrier (6) and is loaded by a compression spring (12). Three locking notches (13) assigned to the locking pin (11) are formed on the weapon barrel (2). In addition, a handle member (14) is attached to the nozzle holder (6).
Die Funktionsweise der beschriebenen Vorrichtung ist etwa folgende:The operation of the described device is approximately as follows:
In den Figuren 1 und 2 ist die Mittelstellung des Düsenträgers(6) gegenüber dem Waffenrohr(2) gezeigt. Der Raststift(11) steht in der mittleren Rastkerbe(13) (vgl. Figur 2). Die Düse(8) liegt im Gaskanal(3,4). Sie steht also zwischen dem im Waffenrohr(2) verlaufenden Teil des Gaskanals(3) und dem im Waffenrohr(2) verlaufenden Teil des Gaskanals(4).FIGS. 1 and 2 show the central position of the nozzle holder (6) relative to the weapon barrel (2). The locking pin (11) is in the middle locking notch (13) (see FIG. 2). The nozzle (8) is in the gas channel (3,4). It stands between the part of the barrel that runs in the weapon barrel (2) Gas channel (3) and the part of the gas channel (4) running in the weapon barrel (2).
In der in Figur 2 dargestellten Stellung stehen die Düsen(8′ bzw. 8˝) in den beiden in Figur 1 nicht zu sehenen Gaskanälen.In the position shown in Figure 2, the nozzles (8 'and 8˝) are in the two gas channels not shown in Figure 1.
Bei einem Schuß wirkt der dabei im Waffenrohr(2) auftretende Druck über die drei Gaskanäle(3), die Dichtdüsen(5), die Düsen(8,8′,8˝) und die Gaskanäle(4) auf die an die Gaskanäle(4) angeschlossenen Einrichtungen, wie Verschlußeinrichtung und Munitionszuführeinrichtung der Maschinenwaffe. Die Dichtdüsen(5) dienen der Abdichtung des Spaltes zwischen dem Düsenträger(6) und dem Waffenrohr(2). Die Düsen(8,8′,8˝) reduzieren den Druck auf das für die genannten Einrichtungen geeignete Maß.In the event of a shot, the pressure occurring in the weapon barrel (2) acts via the three gas channels (3), the sealing nozzles (5), the nozzles (8,8 ′, 8˝) and the gas channels (4) on the gas channels ( 4) Connected devices, such as a locking device and ammunition feeder for the machine gun. The sealing nozzles (5) serve to seal the gap between the nozzle holder (6) and the weapon barrel (2). The nozzles (8,8 ', 8˝) reduce the pressure to the level suitable for the devices mentioned.
Ist zu erwarten, daß beim geplanten Schuß die Düsen(8,8′,8˝) den für die Einrichtungen nötigen Druck nicht auf das richtige Maß einstellen, dann wird der Düsenträger(6) am Griffglied(14) in Richtung des Pfeiles(L) nach links gedreht. Der Raststift(11) rastet dann in die linke Rastkerbe(13). Es stehen nun nicht mehr die Düsen(8,8′,8˝), sondern die Düsen(9,9′,9˝) in den Gaskanälen(3,4). Die freien Querschnitte der Düsen(9) sind so bemessen, daß sie den Gasdruck des Waffenrohrs(2) auf das für den Antrieb der genannten Einrichtungen geeignete Maß reduzieren.If it is to be expected that the nozzles (8,8 ', 8˝) will not set the pressure required for the devices to the correct level during the planned shot, then the nozzle holder (6) on the handle member (14) in the direction of the arrow (L ) turned to the left. The locking pin (11) then snaps into the left locking notch (13). There are no longer the nozzles (8,8 ', 8˝), but the nozzles (9,9', 9˝) in the gas channels (3,4). The free cross sections of the nozzles (9) are dimensioned in such a way that they reduce the gas pressure of the weapon barrel (2) to the level suitable for driving the devices mentioned.
Selbstverständlich ist es möglich, auch mehr als zwei Düsen(8,9) für jeden der Gaskanäle(3,4) vorzusehen.Of course, it is also possible to provide more than two nozzles (8, 9) for each of the gas channels (3, 4).
Wird der Düsenträger(6) in Richtung des Pfeiles(r) gedreht, dann rastet der Raststift(11) in die rechte Rastkerbe(13). Dadurch gelangt ein Bereich(15) des Düsenträgers(6) zwischen den Gaskanal(3) und den Gaskanal(4), der keine Düse aufweist und die Gaskanäle(3,4) gegeneinander absperrt. Die Waffe ist dadurch abgestellt, da der Verschluß und die Munitionszuführeinrichtung vom Gasdruck des Waffenrohrs(2) nicht mehr betätigt werden können. Es ist auch möglich, eine Stellung des Düsenträgers(6) vorzusehen, in der nur die für den Antrieb des Verschlusses der Waffe vorgesehenen Gaskanäle oder nur der für den Antrieb der Munitionszuführeinrichtung vorgesehene Gaskanal abgesperrt wird.If the nozzle holder (6) is turned in the direction of the arrow (r), then the locking pin (11) snaps into the right locking notch (13). As a result, an area (15) of the nozzle carrier (6) passes between the gas channel (3) and the gas channel (4), which has no nozzle and which Shut off gas channels (3,4) against each other. The weapon is switched off because the breech and the ammunition supply device can no longer be actuated by the gas pressure of the weapon barrel (2). It is also possible to provide a position of the nozzle carrier (6) in which only the gas channels provided for driving the breech of the weapon or only the gas channel provided for driving the ammunition supply device is blocked.
