Description

Die Erfindung beschäftigt sich mit einer Lagerung eines Gaskolbens in einem Waffensystem für den Waffen- und Zuführantrieb. Um zu erreichen, dass ein derartiges Waffensystem einen erhöhten Lastwechsel besser aufnehmen kann, ist die Verwendung längerer Schließfedern und Schließfederhülsen angedacht. Um längere Schließfedern und Schließhülsen in das Waffensystem einbinden zu können, wird die Lagerung des / der Gaskolben für den Waffen- und Zuführantrieb nunmehr am oder im Waffenrohr vorgenommen, der Gaskolben aus dem Waffengehäuse herausgenommen. Dadurch steht den Schließfedern und den Schließhülsen der gesamte Raum im Waffengehäuse zur Verfügung.
Bei eigen angetriebenen Waffensystemen, wie bei einem Gasdrucklader, erfolgt das Nachladen und das Bewegen eines Verschlusses durch den Druck der Pulvergase. Diese wirken über Bohrungen und über wenigstens ein Gaskolbensystem auf den Verschluss ein. Ein derartiges Waffensystem mit Schließfedervorrichtung wird in der DE 10 2009 056 253 B3 behandelt.
Die CH 229 628 A offenbart einen Gasdrucklader, bei dem der von den abgezapften Gasen des Laufes beeinflusste Gaskolben den Lauf hülsenförmig umgibt und über Gestänge oder dergleichen den Verschluss zum Entriegeln und Zurückführen nach dem Schuss bringt. Der Gaskolben ist hier derart ausgebildet, dass dieser das hintere Ende des Laufs und auch als Tragorgan das mit dem Lauf verriegelbare Verschlussstück umgibt.
Aus der DE 199 03 610 A ist ein Antriebssystem für eine Gasdrucklader bekannt, der wenigstens zwei Gaskolbensysteme umfasst. Diese sind parallel zum Lauf ausgerichtet und spiegelsymmetrisch zur Längsschnittebene des Gasdruckladers angeordnet. Die Gaskolbensysteme sind ihrerseits bis zum vorderen Ende des Waffenlaufs geführt und an ihrem hinteren Ende über ein Zwischenstück mit dem Verschluss gekoppelt. Die vorgesehenen Schließfedern sind ihrerseits am hinteren Ende des Verschlusses eingebunden.The invention relates to a storage of a gas piston in a weapon system for the weapon and feed drive. In order to achieve that such a weapon system can better absorb an increased load change, the use of longer closing springs and closing spring sleeves is being considered. In order to integrate longer closing springs and closing sleeves in the weapon system, the storage of the / the gas piston for the weapon and feed drive is now made on or in the barrel, the gas piston removed from the weapon housing. As a result, the closing springs and the closing sleeves of the entire space in the weapon housing is available.
In self-propelled weapon systems, such as a gas pressure loader, the reloading and movement of a closure is done by the pressure of the powder gases. These act through holes and at least one gas piston system on the closure. Such a weapon system with closing spring device is in the DE 10 2009 056 253 B3 treated.
The CH 229 628 A discloses a gas pressure supercharger in which the gas piston influenced by the tapped gases of the barrel surrounds the barrel in a sleeve-like manner and brings the closure for unlocking and returning after the shot via rods or the like. The gas piston is designed here so that it surrounds the rear end of the barrel and also as a support member which can be locked with the barrel closure piece.
From the DE 199 03 610 A a propulsion system for a gas pressure supercharger is known which comprises at least two gas piston systems. These are aligned parallel to the barrel and arranged mirror-symmetrically to the longitudinal sectional plane of the gas pressure supercharger. The gas piston systems are in turn guided to the front end of the gun barrel and coupled at its rear end via an intermediate piece with the closure. The proposed closing springs are in turn involved at the rear end of the closure.

Die DE 10 2005 062 758 B betrifft eine Gasabnahmeanordnung für den Waffenlauf, dessen Laufbohrung in kommunizierender Verbindung mit einem Gaszylinder steht, welcher mit einer ersten Gasaustrittsöffnung versehen ist, die mit einem Drosselelement zusammenwirkt. Lauf, Gaszylinder, erste Gasaustrittsöffnung und Drosselelement sind so ausgebildet, dass eine temperaturbedingte Längenänderung des Laufs eine Relativbewegung zwischen Gaszylinder und Drosselelement bewirkt.The DE 10 2005 062 758 B relates to a gas take-off arrangement for the gun barrel, the barrel bore is in communication with a gas cylinder, which is provided with a first gas outlet opening, which cooperates with a throttle element. Run, gas cylinder, first gas outlet opening and throttle element are formed so that a temperature-induced change in length of the barrel causes a relative movement between the gas cylinder and the throttle element.

Andere Ausführungen umfassen anstelle eines Gaskolbensystems mit direkter Verbindung zum Verschluss einen Gaskolben, der mit einem ein Schließfedersystem zusammen auf den Verschluss einwirkt.Other embodiments include, instead of a gas piston system with direct connection to the closure, a gas piston which cooperates with a closing spring system on the closure.

Derartige Schließfedern und Antriebselemente (Gaskolben) sind in einem gemeinsamen Gehäuse, dem Waffengehäuse, untergebracht. Diese Tatsache begrenzt die maximal mögliche Länge der Schließfeder. Der begrenzte Raum bringt schließlich den Nachteil mit sich, dass diese Schließfedern eine Erhöhung des Lastwechsels auf die Schließfedern nicht mehr ausreichend aufnehmen können.Such closing springs and drive elements (gas piston) are housed in a common housing, the weapon housing. This fact limits the maximum possible length of the closing spring. The limited space finally brings with it the disadvantage that these closing springs can no longer sufficiently absorb an increase in the load change on the closing springs.

Hier stellt sich die Erfindung die Aufgabe, eine Erhöhung des Lastwechsels auf die Schließfedern zu ermöglichen, die bekannten Nachteile zu eliminieren.Here, the invention has the object to allow an increase in the load change on the closing springs to eliminate the known disadvantages.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.The problem is solved by the features of claim 1. Advantageous embodiments are listed in the subclaims.

Der vorliegenden Erfindung liegt die Idee zugrunde, einen erhöhten Lastwechsel der Schließfedern durch möglichst lange, maximale Federn einer Schließfeder aufzufangen. Um diese Idee umsetzten zu können, wird daher vorgeschlagen, die Lagerung des Gaskolbens nicht wie bisher im gemeinsamen Gehäuse, dem Waffengehäuse vorzusehen, sondern diesen aus dem Gehäuse herauszunehmen. Dadurch wird die gesamte Länge des Waffengehäuses für die Einbindung längerer als auch stärkerer Federn nutzbar. Das wird dadurch erreicht, dass der / die Gaskolben (Antriebselement) mit den notwendigen Gaskanal / Gaskanälen nunmehr am bzw. im Waffenrohr / Waffenlauf gelagert wird. Der Gaskolben steht über diesen Gaskanal / diese Gaskanäle mit dem Waffenrohr in Verbindung.The present invention is based on the idea to absorb an increased load change of the closing springs by as long as possible, maximum springs of a closing spring. In order to implement this idea, it is therefore proposed not to provide the storage of the gas piston as before in the common housing, the weapon housing, but to take this out of the housing. As a result, the entire length of the weapon housing for the integration of longer and stronger springs available. This is achieved by the / the gas piston (drive element) is now stored with the necessary gas channel / gas channels on or in the barrel / gun barrel. The gas piston is connected via this gas channel / channels with the gun barrel.

Aus der DE 89 09 417 U1 ist eine Vorrichtung für eine Waffe mit einem Waffenlauf mit Laufbohrung sowie mit einem Verschlussschlitten bekannt, bei welcher von der Laufbohrung im hinteren Bereich eine Gasdruckbohrung abzweigt, die zur hinteren Stirnseite des Waffenlaufs führt. Zur Erhöhung der Rückstoßkraft auf den Verschlussschlitten arbeitet diese Vorrichtung mit einem an dem Verschlussschlitten angeordneten Gegenglied zusammen. Schließfedern oder dergleichen werden hier weder erwähnt noch die Problematik der Belastung der Schließfedern etc. angedacht.From the DE 89 09 417 U1 is a device for a gun with a gun barrel with barrel bore and with a closing slide known in which from the barrel hole in the rear region branches off a gas pressure bore leading to the rear end of the gun barrel. To increase the recoil force on the shutter this device works with a arranged on the closure slide counter member together. Closing springs or the like are not mentioned here nor the problem of loading the closing springs, etc. thought.

Eine Gasdruck-Ladeeinrichtung, die oberhalb des Waffenrohres angeordnet ist, beschreibt die DE 32 44 316 A1 . Hierbei werden der Gasdruck-Ladeeinrichtung die Eigenschaften eines Rückstoßladers aufgeprägt. Die Problematik des Lastwechsels wird hier ebenfalls nicht weiter betrachtet. Vielmehr wird darauf hingewiesen, dass die Masse des Schiebers und die Kraft der Feder so ausgewählt werden, dass auch bei unterschiedlichen Munitionsarten ein einwandfreier Ladungsvorgang gewährleistet wird.A gas pressure charging device, which is located above the gun barrel, describes the DE 32 44 316 A1 , In this case, the properties of a recoil charger are impressed on the gas pressure charging device. The problem of the load change is also not considered here. Rather, it should be noted that the mass of the slider and the force of the spring are selected so that even with different types of ammunition a perfect charging process is guaranteed.

Aus der US 4,467,697 A ist ein Waffensystem bekannt, bei welchem ein Verschluss über wenigstens einen Gaskolben und eine sich diesem baulich anschließende und mit dieser zusammenwirkenden Schließfedervorrichtung bewegt wird.From the US 4,467,697 A a weapon system is known in which a closure over at least one gas piston and a structurally adjoining and cooperating with this closing spring device is moved.

Der / die nach der vorliegenden Erfindung aus dem Waffengehäuse ausgelagerte(n) Gaskolben ist / sind bevorzugt in einem eigenen Gaskolbengehäuse untergebracht, das am bzw. um das Waffenrohr herum angebracht ist. Die notwendigen Gaskanäle sind ihrerseits im Gaskolbengehäuse eingebunden.The gas piston (s) paged out of the weapon housing according to the present invention is / are preferably housed in a separate gas piston housing mounted on or around the weapon barrel. The necessary gas channels are in turn integrated in the gas piston housing.

Alternativ kann das Gaskolbengehäuse auch Teil des Waffenrohres und in diesen eingebunden sein.Alternatively, the gas piston housing may also be part of the weapon barrel and integrated into it.

Ist eine Gasentnahme vorn am Waffenrohr erwünscht, kann das Gas über separate Gasführungen zum Gaskolben (Gaskolbengehäuse, Waffenrohr) geführt werden.If a gas extraction at the front of the weapon barrel is desired, the gas can be guided via separate gas guides to the gas piston (gas piston housing, weapon barrel).

Die Schließfedervorrichtung ist so im Waffengehäuse eingebunden, dass der Gaskolben die Schließfederhülse betätigen und verschieben kann. Entsprechend ist das Waffengehäuse in diesem Bereich zum Waffenrohr hin offen, so dass der Gaskolben auch weiterhin direkt auf die Schließfedereinrichtung einwirken kann.The closing spring device is integrated in the weapon housing so that the gas piston can actuate and move the closing spring sleeve. Accordingly, the weapon housing in this area is open to the gun barrel, so that the gas piston can continue to act directly on the closing spring device.

Vorgeschlagen wird somit ein Waffensystem mit einem Waffenrohr, einem Waffengehäuse und einem, in dem Waffengehäuse geführten Verschluss. Dieser Verschluss ist über wenigstens einen Gaskolben und eine sich diesem baulich anschließende, mit dem Gaskolben zusammenwirkende Schließfedervorrichtung bewegbar. Dabei sind Gaskanäle zwischen dem Waffenrohr und dem Gaskolben vorhanden. Um zu erreichen, dass ein Lastwechsel von den Schließfedern besser aufgenommen werden kann, ist vorgesehen, dass der Gaskolben nunmehr am oder im Waffenrohr gelagert wird und nur noch die Schließfedervorrichtung im Waffengehäuse integriert ist. Durch diese Konstruktion kann die Gesamtlänge des Waffengehäuses nunmehr für die Schließfedern bzw. die Schließfedervorrichtung allein / voll genutzt werden.Thus, a weapon system with a weapon barrel, a weapon housing and a shutter guided in the weapon housing is proposed. This closure can be moved by way of at least one gas piston and a closure spring device which adjoins this structurally following gas spring cooperating with the gas piston. There are gas channels between the gun barrel and the gas piston. In order to achieve that a load change from the closing springs can be better absorbed, it is provided that the gas piston is now stored on or in the barrel and only the closing spring device is integrated in the weapon housing. By this construction, the total length of the weapon housing can now be used alone / fully for the closing springs or the closing spring device.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigt die einzige Figur eine skizzenhafte Darstellung der Erfindung. Dabei wird von einem symmetrischen Antriebssystem ausgegangen, bestehend aus zwei Gaskolben und zwei Schließfedervorrichtungen.Reference to an embodiment with drawing, the invention will be explained in more detail. The single figure shows a sketchy representation of the invention. It is assumed that a symmetrical drive system consisting of two gas piston and two Schließfedervorrichtungen.

Mit 10 ist ein Gasdrucklader gekennzeichnet, der ein Waffengehäuse 1 sowie ein Waffenrohr 2 umfasst. Das Waffenrohr 2 ist endseitig im vorderen Bereich des Waffengehäuses 1 eingebunden. Die Patronenzufuhr einer Patrone bzw. Munition 11 in die Patronenkammer 8 des Waffenrohres 2 erfolgt herkömmlich über einen Verschluss 7. Dieser wird, wie bereits ausgeführt, durch bevorzugt zwei Schließfedervorrichtungen 13 innerhalb des Waffengehäuses 1 bewegt.
Die Schließfedervorrichtungen 13 wirken mit je einem Gaskolben 4 funktionell zusammen. Die Gaskolben 4 sind ihrerseits nunmehr in einem Gaskolbengehäuse 3, welches im hinteren Bereich des Waffenrohres 2 angeordnet ist, eingebunden. Das Gaskolbengehäuse 3 kann aber auch Teil des Waffenrohres 2 sein. Die Schließfedervorrichtungen 13 umfassen je eine Schließfederhülse 6 und eine Schließfeder 5, wobei Nocken 9 der Schließfedervorrichtung 13 an den Verschluss 7 eingreifen. Die Schließfedervorrichtungen 13 sind ihrerseits im Waffengehäuse 1 integriert. Die Gasentnahme für die Gaskolben 4 des Gasdruckladers 10 erfolgt über Gaskanäle 14 zwischen den Gaskolben 4 und dem Waffenrohr 2.
Die Gaskanäle 14 können bei einer dem Waffengehäuse nahen Gasentnahme Bestandteil des Gaskolbengehäuses 3 sein. Erfolgt die Gasentnahme weiter vorn, kann die Gaszuführung zum Gaskolben über separate Zuführungen erfolgen, die in das Gaskolbengehäuse geführt werden (nicht näher dargestellt).10 is a gas pressure loader comprising a weapon housing 1 and a gun barrel 2. The weapon barrel 2 is integrated at the end in the front region of the weapon housing 1. The cartridge feed of a cartridge or ammunition 11 in the cartridge chamber 8 of the gun barrel 2 is conventionally via a closure 7. This is, as already stated, preferably moved by two Schließfedervorrichtungen 13 within the weapon housing 1.
The closing spring devices 13 interact functionally with one gas piston 4 each. The gas piston 4 are in turn now in a gas piston housing 3, which is arranged in the rear region of the gun barrel 2, integrated. The gas piston housing 3 may also be part of the gun barrel 2. The closing spring devices 13 each comprise a closing spring sleeve 6 and a closing spring 5, wherein cams 9 of the closing spring device 13 engage the closure 7. The Schließfedervorrichtungen 13 are in turn integrated in the weapon housing 1. The gas removal for the gas piston 4 of the gas pressure supercharger 10 via gas channels 14 between the gas piston 4 and the gun barrel. 2
The gas channels 14 may be part of the gas piston housing 3 at a close to the weapon housing gas sampling. If the gas removal further forward, the gas supply to the gas piston via separate feeds done, which are fed into the gas piston housing (not shown).

Die Funktionsweise ist wie folgt:The operation is as follows:

Nach erfolgtem Verschuss der Munition11 bilden sich kurzfristig Treibgase, die über die Bohrungen bzw. Gaskanäle 14 in die Kolbenführungen der Gaskolben 4 eindringen. Diese Gase wirken auf den oder die Gaskolben 4 ein, die nach hinten bewegt wird / werden. Infolge dessen werden auch die angrenzenden Schließfederhülsen 6 nach hinten bewegt. Durch diese wird der Verschluss 7 nach hinten geführt. Dabei werden die Schließfedern 5 zusammengedrückt und gespannt. Dem Verschluss 7 wird in seiner hinteren Position eine neue Munition 11 vorgelegt. Durch Entspannen der Schließfedern 5 werden die Schließfederhülsen 6 und damit der Verschluss 7 nach vorne bewegt, die Munition 11 der Patronenkammer 8 des Waffenrohres 2 zugeführt. Gleichzeitig werden der / die Gaskolben 4 in die Ausgangslage überführt.After the firing of ammunition 11, propellant gases are formed at short notice, which penetrate via the bores or gas channels 14 into the piston guides of the gas pistons 4. These gases act on the gas piston or 4, which is moved backwards. As a result, the adjacent closing spring sleeves 6 are moved to the rear. By this, the shutter 7 is guided to the rear. The closing springs 5 are compressed and tensioned. The closure 7 is presented in its rear position a new ammunition 11. By relaxing the closing springs 5, the closing spring sleeves 6 and thus the closure 7 are moved forward, the ammunition 11 of the cartridge chamber 8 of the gun barrel 2 fed. At the same time, the gas piston 4 is transferred to the starting position.

Dadurch, dass das Gaskolbengehäuse 3 Teil des Waffenrohres 2 bzw. als eigenständiges Teil auf dem Waffenrohr 2 befestigt ist, können nunmehr längere Schließfedern 5 als auch Schließfederhülsen 6 (= Schließvorrichtung) in das Waffensystem eingebunden werden.The fact that the gas piston housing 3 is part of the gun barrel 2 or attached as an independent part on the gun barrel 2, now longer closing springs 5 and closing spring sleeves 6 (= closing device) can be integrated into the weapon system.
