Abstract

Eine Schußwaffe (1) weist einen Gasantrieb (7) zur schußabhängigen Betätigung einer Lade- und/oder Abschußeinrichtung (4) auf, wobei der Gasantrieb (7) aus einem Gaszylinder (9) und einem Gaskolben (8) besteht und Gaszylinder (9) und Gaskolben (8) durch Pulvergasbeaufschlagung des über eine Querlbhrung (10) an die Laufseele angeschlossenen Zylinderraumes (11) relativ zueinander gegen die Kraft einer Rückholfeder (12) verschiebbar sind. Um eine einfache, funktionssichere, platz- und gewichtssparende Konstruktion für den Gasantrieb zu erreichen, bildet der Lauf (3) selbst mit einem Bund (8) den feststehenden Gaskolben und ist eine sich über den Bund (8) erstreckende Laufhülse (9) als anschlagbegrenzt längsverschiebbarer Gaszylinder vorgesehen.A firearm (1) has a gas drive (7) for the firing-dependent actuation of a charging and / or launching device (4), the gas drive (7) consisting of a gas cylinder (9) and a gas piston (8) and gas cylinder (9) and gas pistons (8) can be displaced relative to one another against the force of a return spring (12) by applying powder gas to the cylinder space (11) connected to the running core via a transverse bore (10). In order to achieve a simple, reliable, space-saving and weight-saving construction for the gas drive, the barrel (3) itself forms the fixed gas piston with a collar (8) and a barrel sleeve (9) extending over the collar (8) is limited as a stop longitudinally displaceable gas cylinder is provided.

Description

Die Erfindung bezieht sich auf eine Schußwaffe mit einem Gasantrieb zur schußabhängigen Betätigung einer Lade- und/­oder Abschußeinrichtung, wobei der Gasantrieb aus einem Bund od.dgl. des Laufes selbst als Gaskolben und einer sich über den Bund erstreckenden Laufhülse als Gaszylinder besteht und die Laufhülse durch Pulvergasbeaufschlagung ihres über wenigstens eine Querbohrung an die Laufseele angeschlossenen Zylinderraumes relativ zum Lauf gegen die Kraft einer Rückholfeder anschlagbegrenzt verschiebbar ist.The invention relates to a firearm with a gas drive for the shot-dependent actuation of a loading and / or launching device, the gas drive or the like from a bundle. of the barrel itself as a gas piston and a barrel sleeve extending over the collar as a gas cylinder and the barrel sleeve can be displaced with respect to the barrel against the force of a return spring by powder gas application of its cylinder space connected to the barrel core via at least one transverse bore.

Um eine Schußwaffe teilweise oder vollständig automati­sieren zu können, muß für einzelne Schritte des Lade- und Entladevorganges oder für den gesamten Lade- und Zündvor­gang eine Antriebsmöglichkeit vorgesehen sein und Gasan­triebe zur Nutzung der nach der Schußabgabe noch in den Pulvergasen steckenden Restenergie haben sich als zweckmäs­sige Antriebsquelle bereits durchaus bewährt. Allerdings bestehen bisher die Gasantriebe aus eigenen, vom Lauf ge­trennten Kolben-Zylinder-Einheiten, wobei die Zylinder fest mit dem Lauf oder dem Gehäuse verbunden sind und der beweg­liche Hubkolben die entsprechenden Teile der Lade- und/oder Abschußeinrichtung über eine Kolbenstange od.dgl. betätigt. Diese Kolben-Zylindereinheiten umfassen eine größere Anzahl teurer Bestandteile und erfordern daher einen beträchtlichen Bauaufwand, sie nehmen viel wertvollen Platz für sich in Anspruch und bringen außerdem eine entsprechende Erhöhung des Waffengewichtes mit sich.In order to be able to partially or completely automate a firearm, a drive option must be provided for individual steps of the loading and unloading process or for the entire charging and ignition process, and gas drives for using the residual energy still present in the powder gases after the firing of the shot have proven to be a suitable drive source already proven. However, so far the gas drives consist of their own piston-cylinder units separate from the barrel, the cylinders being firmly connected to the barrel or the housing and the movable reciprocating piston or the like, the corresponding parts of the loading and / or launching device via a piston rod. operated. These piston-cylinder units comprise a large number of expensive components and therefore require a considerable amount of construction, they take up a lot of valuable space and also bring about a corresponding increase in the weight of the weapon.

Der Erfindung liegt somit die Aufgabe zugrunde, diese Mängel zu beseitigen und eine Schußwaffe der eingangs ge­schilderten Art zu schaffen, die sich durch eine besonders einfache und funktionssichere, leichte und platzsparende Konstruktion ihres Gasantriebes auszeichnet.The invention is therefore based on the object to remedy these defects and to provide a firearm of the type described, which is characterized by a particularly simple and reliable, light and space-saving construction of its gas drive.

Die Erfindung löst diese Aufgabe dadurch, daß der Lauf im Verschiebebereich der Laufhülse Ringnuten, aufweist und vorzugsweise der dem Bund gegenüberliegende Endanschlag für die Laufhülse federnd ausgebildet ist.The invention solves this problem in that the barrel has annular grooves in the displacement area of the barrel and preferably the end stop opposite the collar is designed to be resilient for the barrel.

Die erfindungsgemäßen Ringnuten im Verschiebebereich der Laufhülse ergeben nicht nur eine die Verschmutzungsgefahr herabsetzerde Labyrinthrichtung, sondern sie erlauben auch einen über den gesamten Rücklauf der Laufbüchse wirkenden Antrieb, was im Gegensatz zu den bekannten Gasantrieben steht, die stets nur impulsartig wirken. Es kommt zu einer entsprechenden Antriebsleistung, so daß zur Dämpfung des Aufpralles der Laufhülse am Endanschlag dieser vorteilhaften Weise federnd ausgebildet ist. Der federnde Endanschlag verstärkt zusätzlich die Wirkung der Rückholfeder, was vor allem im Umkehrbereich eine bedeutende Rolle spielt.The ring grooves according to the invention in the sliding area of the barrel not only result in a labyrinth direction which reduces the risk of contamination, but they also allow a drive which acts over the entire return of the barrel, which is in contrast to the known gas drives, which always act only in pulses. There is a corresponding drive power, so that in order to dampen the impact of the sleeve at the end stop this advantageous manner is resilient. The resilient end stop additionally reinforces the effect of the return spring, which plays an important role especially in the reversing area.

Dient erfindungsgemäß als Endanschlag eine den Lauf umschließende Büchse, die sich axial am den Lauf aufnehmen­den Gehäuse abstützt und im frei vorragenden Anschlagende mit Querschlitzen versehen ist, ergibt sich eine einfache Konstrukticn für den Endanschlag, der außerdem eine ge­wünscht steife Federcharakteristik erhält.If, according to the invention, a bush enclosing the barrel is used as the end stop, which is supported axially on the housing receiving the barrel and is provided with transverse slots in the freely projecting stop end, there is a simple construction for the end stop, which also receives a desired stiff spring characteristic.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt, und zwar zeigen

  • Fig. 1 eine erfindungsgemäße Schußwaffe im Längsschnitt und
  • Fig. 2 diese Schußwaffe in gleicher Schnittdarstellung mit ausgefahrenem Gasantrieb.
In the drawing, the subject matter of the invention is shown in one embodiment, namely show
  • Fig. 1 shows a firearm according to the invention in longitudinal section and
  • Fig. 2 this firearm in the same sectional view with the gas drive extended.

Eine nur angedeutete Schußwaffe 1 besteht im wesentlichen aus einem Gehäuse 2, einem Lauf 3 und einer Lade- und Ab­schußeinrichtung 4 mit Abzug 5. Zur Betätigung dieser Lade-­und Abschußeinrichtung 4 ist ein in Laufrichtung verschieb­bar geführtes Gleitstück 6 vorgesehen, das über einen Gas­antrieb 7 schußabhängig bewegt wird. Der Gasantrieb 7 be­steht aus einem als Gaskolben dienenden Bund 8 des Laufes 3 und einer den zugehörigen Gaszylinder bildenden Laufhülse 9, die sich über den Bund 8 erstreckt und längsverschiebbar am Lauf 3 sitzt. Über eine Querbohrung 10 in der Stirnfläche 8a des Bundes 8 ist der Zylinderraum 11 zwischen Bund 8 und dem an den Lauf 3 angepaßten Gleitsitz 9a der Laufhülse 9 mit der Laufseele verbunden und daher über diese Querboh­rung 10 mit Pulvergasen nach einer Schußabgabe beaufschlag­bar. Zur Abdichtung der Laufhülse 9 gegenüber Lauf 3 bzw. Bund 8 sind im Lauf 3 bzw. im Bund 8 Ringnuten 3a und 8b im Verschiebebereich der Laufhülse 9 vorgesehen.An indicated firearm 1 essentially consists of a housing 2, a barrel 3 and a loading and firing device 4 with trigger 5. To actuate this loading and firing device 4, a sliding piece 6 is provided which is displaceable in the barrel direction and which is operated by a gas drive 7 is moved depending on the shot. The gas drive 7 consists of a collar 8 of the barrel 3 serving as a gas piston and a barrel sleeve 9 forming the associated gas cylinder, which extends over the collar 8 and is longitudinally displaceable on the barrel 3. Via a transverse bore 10 in the end face 8a of the collar 8, the cylinder space 11 between the collar 8 and the sliding seat 9a of the barrel 9, which is adapted to the barrel 3, is connected to the barrel core and can therefore be charged with powder gases via this transverse bore 10 after a shot has been fired. To seal the running sleeve 9 with respect to the barrel 3 or collar 8, annular grooves 3a and 8b are provided in the barrel 3 or collar 8 in the displacement area of the barrel sleeve 9.

Die Laufhülse 9 ist durch Gasbeaufschlagung des Zylinder­raumes 11 gegen die Kraft einer Rückholfeder 12 verschieb­bar, wobei ein Endanschlag 13 die Verschiebebewegung der Laufhülse 9 begrenzt. Als Endanschlag 13 ist eine sich am Gehäuse 2 abstützende Büchse 14 vorgesehen, die im frei vorragenden Anschlagende 14a Querschlitze 15 aufweist, so daß ein federnder Anschlag für die Laufhülse 9 entsteht.The sleeve 9 is displaceable against the force of a return spring 12 by applying gas to the cylinder space 11, an end stop 13 limiting the displacement movement of the sleeve 9. A bush 14, which is supported on the housing 2 and has transverse slots 15 in the freely projecting stop end 14 a, is provided as the end stop 13, so that a resilient stop for the barrel sleeve 9 is produced.

Um die Betätigung der Lade- und Abschußeinrichtung 4 über den Gasantrieb 7 bewerkstelligen zu können, greift das Gleitstück 6 an einer mit der Laufhülse 9 verbundenen Mit­nahmemanschette 16 an, so daß die Verschiebebewegung der Laufhülse 9 direkt auf das Gleitstück 6 übertragen und die Lade- und Abschußeinrichtung 4 betätigt wird. Nach jeder Schußabgabe treten Pulvergase durch die Querbohrung in den Zylinderraum 11 und auf Grund dieser Gasbeaufschlagung wird die Laufhülse 9 gegen den Endanschlag 13 bewegt. Ist der Abzug 5 durchgezogen, wirft die Rückholfeder 12 die Lauf­hülse 9 sofort wieder zurück, wobei die durch die Quer­schlitze 15 im Anschlagende 14a entstehende Pufferfeder einerseits den Aufprall der Laufhülse 9 auf dem Endanschlag 13 dämpft und anderseits die Bewegungsumkehr beschleunigt. Wird hingegen der Abzug 5 nach Brechen des Schusses losge­lassen, fängt der Abzug im dargestellten Ausführungsbeispiel das Gleitstück 6 in ausgefahrener Lage (Fig. 2) und unter­bricht den Bewegungsablauf, was im Gegensatz zum Dauerfeuer bei durchgezogenem Abzug 5 das Schießen von Einzelfeuer erlaubt.In order to be able to actuate the loading and firing device 4 via the gas drive 7, the slider 6 engages with a driving sleeve 16 connected to the running sleeve 9, so that the displacement movement of the running sleeve 9 is transmitted directly to the slider 6 and the loading and Launcher 4 is operated. After each shot is fired, powder gases pass through the transverse bore into the cylinder chamber 11 and, due to this gas application, the barrel sleeve 9 is moved against the end stop 13. If the trigger 5 is pulled, the return spring 12 throws the barrel sleeve 9 back immediately, the buffer spring created by the transverse slots 15 in the stop end 14a on the one hand damping the impact of the barrel sleeve 9 on the end stop 13 and on the other hand accelerating the reversal of movement. If, however, the trigger 5 is released after the shot is broken, the trigger in the exemplary embodiment shown catches the slide 6 in the extended position (FIG. 2) and interrupts the sequence of movements, which in contrast to the continuous fire single trigger is allowed when trigger 5 is pulled.
