Description

Aus dem Stand der Technik sind verschiedene Antriebe wie Fremd- oder Eigenantriebe für Waffensysteme bekannt. Bei Fremdantrieben werden häufig elektrische Antriebe vorgesehen, welche dann beispielsweise eine Kette antreiben. Ein bekannter Kettenantrieb wird in der unter dem Namen Bushmaster oder auch Chain Gun bekannten Maschinenkanone angewandt. Hierbei werden notwendige Stillstandszeiten zum Verschließen des Verschlusses, für das Schussauslösen, für das Öffnen des Verschlusses sowie das Vorlegen einer Patrone vor den Verschluss durch eine umlaufende, von einem Motor angetriebene Kette realisiert (http://de.wikipedia.org/wiki/M242 Bushmaster). Der Verschluss mit der davor liegenden Munition bzw. Patrone wird dabei dem Patronenlager linear zugeführt.From the prior art, various drives such as foreign or self-propelled weapon systems are known. In third-party drives electric drives are often provided, which then drive, for example, a chain. A well-known chain drive is used in the known under the name Bushmaster or Chain Gun automatic cannon. Here necessary downtime for closing the shutter, for firing the shot, for opening the shutter and the presentation of a cartridge before the closure by a rotating, driven by a motor chain realized (http://de.wikipedia.org/wiki/M242 Bushmaster) . The closure with the preceding ammunition or cartridge is thereby fed linearly to the cartridge chamber.

In der DE 10 2006 022 622 A1 wird eine lineare Zuführung der Munition in ein Waffenrohr bzw. Patronenlager beschrieben, welche eine zur Funktionssteuerung verwendete Steuerkulisse in der horizontalen Ebene parallel zum Weg eines geradlinig zu führenden Verschlusses der Verschlusswaffe aufweist. Diese wirkt funktional mit einer so genannten gleichfalls in der horizontalen Ebene liegenden Antriebskulisse zum Führen eines mit dem Verschluss verbundenen Mittels zusammen. Die Antriebskulisse ist in einem bewegbaren Schieber integriert, welcher seinerseits durch einen universell gestaltbaren Antrieb verstellt wird. Für eine Verriegelung des Verschlusses ist des Weiteren eine Verriegelungskulisse vorgesehen, die bevorzugt zusammen mit der Antriebskulisse in dem bewegbaren Schieber eingebunden ist. In diese Verriegelungskulisse kann ein Bolzen eines vorzugsweise waffenseitig angeordneten Verriegelungsringes eingreifen. Dieser Bolzen bewegt seinerseits dann den Verriegelungsring. Innerhalb der miteinander wirkenden Steuerkulisse und der Antriebskulisse wird ein Pleuel oder dergleichen durch die Kulissen und den Schieber entlang dieser Kulissen zwangsgeführt. Mit diesem Pleuel wird der Verschluss hin und her bewegt.In the DE 10 2006 022 622 A1 a linear supply of the ammunition is described in a gun barrel or cartridge chamber, which has a control link used for function control in the horizontal plane parallel to the path of a straight-to-leading closure of the closure weapon. This functionally cooperates with a so-called also in the horizontal plane drive link for guiding a connected to the closure means. The drive link is integrated in a movable slide, which in turn is adjusted by a universal design drive. For a locking of the closure further comprises a locking link is provided, which is preferably integrated together with the drive link in the movable slide. In this locking link can engage a bolt preferably a weapon side arranged locking ring. This bolt in turn then moves the locking ring. Within the co-acting control link and the drive link a connecting rod or the like is forcibly guided through the scenes and the slide along these scenes. With this connecting rod, the shutter is moved back and forth.

Darauf aufbauend wird in der nicht vorveröffentlichten DE 10 2007 048 468.4 ein Antrieb für die lineare Zuführung der Munition in ein Waffenrohr bzw. Patronenlager mittels einer Kette näher betrachtet. Die Kette selbst wird in einfacher Art und Weise eng um zwei Kettenräder geführt. Ein Kettenglied bzw. ein Nocken der Kette ist in eine unterhalb des bewegbaren Schiebers befindlichen Führung oder Nut eingebunden. Dadurch kann die Kette innerhalb der Stillstandszeiten der Waffe, die durch die Funktionssteuerung definiert wird, weiter laufen. Die Kette selbst kann durch einen Elektromotor angetrieben werden.Building on this is in the not previously published DE 10 2007 048 468.4 a drive for the linear supply of ammunition in a gun barrel or cartridge chamber by means of a chain considered closer. The chain itself is tightly guided around two sprockets in a simple manner. A chain link or a cam of the chain is in a below the movable Slider located guide or groove involved. This allows the chain to continue running within the downtime of the weapon defined by the function control. The chain itself can be driven by an electric motor.

Da Verschlussbewegungen bei einem Fremdantrieb unabhängig vom Gasdruck im Waffenrohr ablaufen, muss im Fall eine Anzündversagers (nach Zufuhr der Anzündenergie brennt die Treibladung in der Patrone nicht ab) bzw. Spätzünders (hier brennt die Treibladung mit deutlichem Zeitverzug ab) das Öffnen des Verschlusses verhindert werden. Dazu wird in der Regel der Gasdruck oder der Waffenlauf selbst als Indiz für einen ordnungsgemäßen Abbrand detektiert. Fehlt diese Information, muss ein so genannter Schnellstopp ausgelöst und das Öffnen des Verschlusses verhindert werden.Since shutter movements occur in a foreign drive regardless of the gas pressure in the gun barrel, in the case of Anzündversagers (after supply of the ignition does not burn the propellant charge in the cartridge) or retarded (here the propellant burns off with a significant delay) opening the shutter must be prevented , For this purpose, the gas pressure or the weapon barrel itself is usually detected as an indication of proper burnup. If this information is missing, a so-called quick stop must be triggered and the opening of the closure prevented.

Durch die Massenkräfte beim Abbremsen des Fremdantriebes, um das Öffnen zu verhindern, entstehen insbesondere bei höheren Kadenzen hohe Belastungen in bzw. an den Elementen des Antriebsstranges.Due to the inertia forces during braking of the external drive to prevent the opening, high loads occur in or at the elements of the drive train, especially at higher cadences.

Mit der Problematik eines so genannten Schnellstopps bei fremd angetriebenen Waffen beschäftigt sich die nicht vorveröffentlichte DE 10 2007 048 470.6 . Der Schnellstopp wird stetig eingelegt und im Falle eines ordnungsgemäßen Schusses wieder ausgesteuert. Jedoch im Falle eines Zündversagers läuft ein Mittel, welches mit dem Waffenrücklauf funktional verbunden ist, auf den Schnellstopp auf, die Antriebsbewegung wird gestoppt, das Entriegeln des Verschlusses unterbleibt zumindest für eine vorgebbare Zeit.With the problem of a so-called quick stop in foreign-powered weapons deals with the non-pre-published DE 10 2007 048 470.6 , The quick stop is continuously inserted and controlled again in the case of a proper shot. However, in the case of a Zündversagers runs a means which is functionally connected to the weapon return on the quick stop, the drive movement is stopped, the unlocking of the closure is omitted at least for a predetermined time.

Aus der DE 30 21 200 C2 ist ein Schutzsystem gegen verspätetes Losgehen oder Nachzünden bekannt. Die Waffe ist neben einem Fühler zum Erfassen eines Rückstoßes mit einem Schnellstopp ausgerüstet, der zum Anhalten eines sich normalerweise kontinuierlich bewegenden Kettenteils und damit zum Stillsetzen der Bewegung des Verschlusses in eine bezüglich des Kettenteils eingerückte Position bringbar ist. Eine auf den Fühler ansprechende Verriegelungsvorrichtung steuert die Bewegung der Stoppvorrichtung zwischen der eingerückten Position, in welcher das Kettenteil angehalten wird, und einer ausgerückten Position, in der die Bewegung des Kettenteils ansonsten nicht behindert wird. Das Schutzsystem weist zwei mit dem Kettenteil verbundene Glieder auf, ein Hauptglied sowie ein Sicherheitsglied, sowie eine Abzugsstange, die von einem Hubmagneten gesteuert wird, und eine Rückstoßschubstange auf. Die Rückstoßschubstande dient zum Freisetzen eines Rückstoßklinkenriegels, wenn der Schuss gebrochen ist, die Abzugsstange zum Unterstellen des Sicherheitsgliedes beim Verriegeln der Waffe und Freigeben, wenn die Munition richtig abgefeuert ist. Für ein späteres Stillsetzen der Waffe greift die Abzugsstange am Hauptglied an, da der Hubmagnet abgeschaltet ist. Ein derartiger, elektrisch gesteuerter Hubmagnet ist jedoch insbesondere in Sicherheitseinrichtungen dieser Art unerwünscht, da selber störanfällig. Ein möglicher Materialbruch der Stangen macht die Sicherheitseinrichtung zudem nicht funktionssicher. Die gesamte Einheit ist zudem konstruktiv sehr aufwändig.From the DE 30 21 200 C2 is a protection system against late start or Nachzünden known. The weapon is equipped with a rapid stop next to a sensor for detecting a recoil, which can be brought to stop a normally continuously moving chain part and thus to stop the movement of the shutter in an engaged relative to the chain part position. A locking device responsive to the sensor controls the movement of the stop between the engaged position in which the chain member is stopped and a disengaged position in which the movement of the chain member is otherwise unobstructed. The protection system has two links connected to the chain part, a main link and a safety link, and a trigger bar controlled by a solenoid, and a recoil push rod. The recoil burst is for releasing a recoil latch when the shot is broken, the trigger bar for placing the safety member in place when locking the weapon, and releasing when the ammunition is properly fired. For a later shutdown of the weapon, the trigger rod attacks the main member, since the Solenoid is switched off. However, such an electrically controlled solenoid is undesirable in particular in safety devices of this type, since itself prone to failure. A possible material breakage of the rods also makes the safety device not functionally reliable. The entire unit is also structurally very complex.

Die DE 32 18 550 C2 offenbart eine Blockiereinrichtung für eine Maschinenkanone mit einem fremd angetriebenen Verschlussantrieb. Hierbei dient eine aus der Schussentwicklung resultierende Energie für eine Schusskontrolleinrichtung zum Unterbrechen der Fremdenergiezufuhr. Bei einem nicht gebrochenen Schuss und dem Ausbleiben einer Rückbewegung wird ein Ausrücken eines Steuernockens der Einrichtung aus einer zurückgezogenen Position in eine Mitnahmeposition verhindert, während ein Schalthebel durch einen Unterbrechernocken in eine Position transportiert wird, in der die kontinuierliche Drosselung der Energiezufuhr erreicht wird. Der Nachteil dieser Lösung liegt gleichfalls im hohen konstruktiven Aufwand und dem damit verbundenen Gewicht.The DE 32 18 550 C2 discloses a blocking device for a machine gun with a foreign-driven shutter drive. This is an energy resulting from the shot development for a shot control device for interrupting the external energy supply. In a non-broken shot and the absence of a return movement, disengagement of a control cam of the device from a retracted position to a take-up position is prevented while a shift lever is transported by a disconnector cam to a position where the continuous restriction of the power supply is achieved. The disadvantage of this solution is also the high design complexity and the associated weight.

Ausgehend von der DE 3 021 200 C2 stellt sich die Erfindung die Aufgabe, einen Antrieb für eine Zuführung des Waffenverschlusses zum Patronenlager aufzuzeigen, bei dem der Verschluss insbesondere im Falle eines Anzündversagers bzw. Spätzünders automatisch vom Antrieb abgekoppelt wird.Starting from the DE 3 021 200 C2 the invention has the object to show a drive for a supply of the weapon lock to the chamber, in which the closure is automatically disconnected from the drive, in particular in the case of Anzündversagers or retarder.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausführungen sind in den Unteransprüchen aufgelistet.The object is achieved by the features of claim 1. Advantageous embodiments are listed in the subclaims.

Der Erfindung liegt ebenfalls die Idee zugrunde, als Antrieb eine Kette einzubinden. Über den Kettenantrieb wird die Drehbewegung des Fremdantriebes, beispielsweise eines elektrischen Motors, in eine Vor- und Zurückbewegung des Verschlusses realisiert. Die Kette besitzt wenigstens zwei Mitnehmernocken. Um die Stillstandszeiten des Verschlusses in den Endlagen zu ermöglichen, wird der Verschluss in seiner vorderen und hinteren Position von den Mitnehmernocken und somit vom Antrieb getrennt.The invention is also based on the idea of integrating a chain drive. About the chain drive, the rotational movement of the external drive, such as an electric motor, realized in a forward and backward movement of the shutter. The chain has at least two drive cams. In order to allow the downtime of the shutter in the end positions, the shutter is separated in its front and rear position by the driving cam and thus the drive.

Die, die Kette antreibenden Kettenräder besitzen ihrerseits einen Radius, durch den infolge einer damit erzeugten Sinusfunktion das Beschleunigen oder Abbremsen des Verschlusses realisiert wird.The sprockets driving the chain in turn have a radius through which the squeezing or deceleration of the shutter is realized as a result of a sinusoidal function generated thereby.

Die wenigstens zwei Mitnehmernocken der Kette greifen in einem Schlitten mit Nut unterhalb des Verschlusses bzw. Verschlussaufnehmers zu seiner Mitnahme. Für die Stillstandzeiten des Verschlusses verlassen die Mitnehmernocken jeweils die Nut. Der Schlitten selbst ist in einer Führung unterhalb des Verschlusses eingebunden und in dieser Führung bewegbar. Er ist bevorzugt nur halb so breit wie der Kettenantrieb. Der Schlitten nimmt dabei nur einen Teil der Gesamtführung ein und kann somit in dieser Führung quer zur Schussrichtung hin und her bewegt werden. Durch eine Feder oder dergleichen wird der Schlitten auf die in Schussrichtung rechte Seite des Verschlusses bzw. des Verschlussaufnehmers gedrückt, sodass der eine Mitnehmernocken der Kette auf seinem Weg in Schussrichtung nach vorn in die Nut des Schlittens eingreift. Durch das Weiterlaufen des Kettenantriebs fährt dieser Mitnehmernocken der Kette auf der linken Seite der Waffenanlage wieder nach hinten und verlässt dabei die Nut im Schlitten, sodass der Verschluss unabhängig vom Antrieb in seiner vordersten, verriegelten Position verbleibt. Der Schlitten selbst wird nach erfolgtem Schuss von seiner rechten Position (in Schussrichtung betrachtet) innerhalb der Führung in seine linke Position überführt. Genutzt wird dazu ein Waffenrücklauf oder alternativ ein Gasdruck. D.h., der dem Zünden der Patrone folgende Waffenrücklauf verschiebt den Schlitten auf die linke Seite des Verschlusses bzw. der Waffenanlage, wo er von einem Hebel etc. gehalten wird. Der zweite Mitnehmernocken auf der Kette fährt nun seinerseits von der rechten Seite in die Nut im Schlitten und nimmt den Verschluss mit in seine hintere Position. Hier verlässt der Mitnehmernocken die Nut wieder, womit die hintere Wartezeit des Verschlusses beginnt. Wird durch einen Zuführer oder dergleichen die Patrone vor den Verschluss gelegt, wird der Schlitten unterhalb des Verschlusses durch Auslösen des (Unterstell-)Hebels von der Feder wieder auf die rechte Seite gedrückt. Der nächste Mitnehmernocken der Kette fährt jetzt von der linken Seite in die Nut im Schlitten und nimmt die gesamte Mimik wieder mit nach vorn. Ist kein Schuss gebrochen, verbleibt der Schlitten in seiner rechten Position und der zweite bzw. nachfolgende Mitnehmernocken kann den Verschluss nicht entriegeln und zurücknehmen.The at least two drive cams of the chain engage in a carriage with a groove below the closure or closure receiver for its entrainment. For the downtime of the shutter leave the drive cam each groove. The sled itself is in a guide incorporated below the closure and movable in this guide. It is preferably only half as wide as the chain drive. The carriage takes only a part of the overall guide and can thus be moved in this guide transversely to the firing direction back and forth. By a spring or the like, the carriage is pressed onto the right in the weft direction side of the closure or the closing receiver, so that the one driving cam of the chain engages on its way in the weft direction forward into the groove of the carriage. As the chain drive continues to move, this chain drive cam on the left side of the weapon system moves backwards, leaving the groove in the carriage, leaving the shutter in its foremost, locked position, independently of the drive. The slide itself is transferred after his shot from its right position (viewed in the weft direction) within the guide in its left position. Used to a weapon return or alternatively a gas pressure. That is, the weapon return following the ignition of the cartridge shifts the carriage to the left side of the shutter or the weapon system, where it is held by a lever, etc. The second drive cam on the chain now moves in turn from the right side into the groove in the carriage and takes the closure with it in its rear position. Here, the drive cam leaves the groove again, whereby the rear waiting time of the closure begins. When the cartridge is placed in front of the shutter by a feeder or the like, the carriage below the shutter is pushed back to the right side by releasing the lever. The next drive cam of the chain now moves from the left side into the groove in the carriage and takes the entire facial expression back to the front. If no shot is broken, the carriage remains in its right position and the second or subsequent driver cam can not unlock the lock and take back.

Fig. 1 zeigt eine Darstellung eines Verschlussantriebs mit einer Kette 6 für eine fremd angetriebene Maschinenkanone (teilweise dargestellt), mit einem Waffenrohr 1, das in einer Rohrverriegelung 2 (hier eine Verriegelungsbuchse) befestigt ist, in der auch ein Verschluss 3 in seiner vorderen Position verriegelt wird. Der Verschluss 3 kann auf Verschlussführungen 4 in und entgegen der Waffenrohrachse verschoben werden. Fig. 1 shows a representation of a shutter drive with a chain 6 for a foreign-powered machine gun (partially shown), with a gun barrel 1, which is in a tube lock 2 (here a locking sleeve) is fixed, in which a shutter 3 is locked in its forward position. The shutter 3 can be moved to shutter guides 4 in and against the Waffenrohrachse.

Vorzugsweise unterhalb der Verschlussführungen 4 bzw. des Verschlusses 3 sind zwei Kettenräder 5 und die Kette 6 mit vorzugsweise zwei Mitnehmernocken 7 angeordnet (um 180° zueinander versetzt). Quer zur Schussrichtung verschiebbar ist in einer Führung unten am Verschluss 3 (bzw. Verschlussaufnehmer) ein Schlitten 8 gelagert, über dessen volle Breite sich eine Nut 9 erstreckt. Über diese Nut 9 bewegt der jeweilige Mitnehmernocken 7 den Verschluss 3 in Schussrichtung nach vorn oder nach dem Schuss nach hinten.Preferably, below the shutter guides 4 and the shutter 3, two sprockets 5 and the chain 6 are arranged with preferably two driving cam 7 (offset by 180 ° to each other). Slidably mounted transversely to the firing direction, a carriage 8 is mounted in a guide at the bottom of the closure 3 (or closure receptacle), over the full width of which a groove 9 extends. About this groove 9, the respective driving cam 7 moves the shutter 3 in the weft direction to the front or after the shot to the rear.

Eines der Kettenräder 5 wird von einem Motor oder dergleichen (direkt oder indirekt) angetrieben und nimmt die Kette 6 mit, sodass sich die Kette 6 auf der, in Schussrichtung gesehen rechten Waffenseite nach vorn und auf der linken Seite nach hinten bewegt. Alternativ kann die Bewegung insgesamt auch entgegengesetzt zu dieser beschriebenen Richtung erfolgen.One of the sprockets 5 is driven by a motor or the like (directly or indirectly) and carries the chain 6 with it, so that the chain 6 moves forwards on the right side of the weapon as seen in the direction of firing and backwards on the left side. Alternatively, the movement can also take place in total opposite to this direction described.

Um den Verschluss 3 nach vorne zu transportieren, wird der auf der rechten Waffenseite befindliche Mitnehmernocken 7 in die Nut 9 des Schlittens 8 eingefädelt. Hierdurch wird eine in Längsrichtung der Waffe formschlüssige Verbindung zwischen Antrieb 2 und Verschluss 3 hergestellt, wobei der Verschluss 3 über eine durch den Radius der Kettenräder 5 vorgegebene Sinusfunktion beschleunigt oder abgebremst wird.In order to transport the closure 3 to the front, the drive cam located on the right side of the weapon 7 is threaded into the groove 9 of the carriage 8. As a result, a form-locking connection between drive 2 and shutter 3 is produced in the longitudinal direction of the weapon, wherein the shutter 3 is accelerated or decelerated via a predetermined by the radius of the sprocket wheels 5 sine function.

Die Stillstandszeiten des Verschlusses 3 in der vorderen Endlage werden dadurch realisiert, dass der Mitnehmernocken 7 aus der Nut 9 herausgefahren und auf der linken Waffenseite ohne Verschluss 3 nach hinten bewegt wird. In der vorderen, verriegelten Position des Verschlusses 3 wird in bekannter Art und Weise ein Schlagbolzen (nicht näher dargestellt) ausgelöst, wodurch eine im Patronenlager befindliche Patrone (beide nicht näher dargestellt) gezündet wird. Der daraufhin einsetzende Waffenrücklauf dient zum Verschieben des Schlittens 8 auf die linke Waffenseite. Alternativen sind möglich, so die Nutzung des sich aufbauenden Gasdrucks beim Schuss.The downtime of the shutter 3 in the front end position are realized in that the drive cam 7 moved out of the groove 9 and is moved to the left side of the weapon without closure 3 to the rear. In the front, locked position of the closure 3 a firing pin (not shown in detail) is triggered in a known manner, whereby a cartridge located in the cartridge chamber (both not shown in detail) is ignited. The ensuing weapon return is used to move the carriage 8 on the left side of the weapon. Alternatives are possible, such as the use of the building up gas pressure during firing.

Die für die Funktion benötigten Elemente 10 bis 15 sind in den Fig. 2 bis 4 beispielhaft zu betrachten, insbesondere unter Berücksichtigung der möglichen Nutzung eines Gasdrucks. Ein Hebel 10 verschiebt beim Waffenrücklauf den Schlitten 8 in seine linke Position und spannt dabei eine Druckfeder 16. Übertragen wird die Rücklaufbewegung vom Waffenrohr 1 auf die Rohrverriegelung 2, die einen Stift 13 mitnimmt. Der Stift 13 und ein Stößel 12 sind in einem waffengehäusefesten Lagerbock 11 in Längsrichtung verschiebbar angeordnet. In Fig. 3 erkennbar ist zwischen einer Hülse, in der der Stift 13 befestigt ist und dem Stößel 12 eine Feder eingebunden. Dadurch wird der Waffenrücklauf nicht starr gekoppelt in eine Drehbewegung des Hebels 10 umgesetzt, sondern über die Feder gepuffert. Somit ist selbst bei unterschiedlich langen Waffenrückläufen immer eine vollständige Verschiebung des Schlittens 8 auf die linke Seite gewährleistet.The elements required for the function 10 to 15 are in the Fig. 2 to 4 to consider as an example, in particular taking into account the possible use of a gas pressure. A lever 10 moves the weapon return the carriage 8 in its left position and thereby biases a compression spring 16. The return movement is transferred from the barrel 1 to the pipe lock 2, which takes a pin 13. The pin 13 and a plunger 12 are slidably disposed in a weapon housing fixed bearing block 11 in the longitudinal direction. In Fig. 3 can be seen between a sleeve in which the pin 13 is fixed and the plunger 12 includes a spring. As a result, the weapon return is not rigidly coupled converted into a rotational movement of the lever 10, but buffered by the spring. Thus, even with different length weapon returns always a complete displacement of the carriage 8 is guaranteed on the left side.

Ein Gestänge 15 wird beim Waffenrücklauf von der Hinterkante der Rohrverriegelung 2 bewegt und dreht den Hebel 10, wodurch die Arretierung des Schlittens 8 aufgehoben wird, der in seiner Ruheposition mit einer Nase den Schlitten 8 in seiner rechten oder linken Position hält (arretiert). Nach erfolgtem Waffenrohrrücklauf (Schuss gebrochen) befindet sich der Schlitten 8 nunmehr auf der linken Waffenseite und wird gegen den Druck der Feder 16 vom Hebel 10 in dieser Position gehalten. Der nächste Mitnehmernocken 7 läuft nun von der rechten Seite in die Nut 9 und nimmt den Verschluss 3 in seine hintere Position mit. In dieser Position verlässt der Nocken 7 die Nut 9, wodurch der Verschluss 3 wieder vom Antrieb 6 (2) abgelegt wird und in seiner Position verbleibt.A linkage 15 is moved in the weapon return from the trailing edge of the pipe lock 2 and rotates the lever 10, whereby the locking of the carriage 8 is released, which holds in its rest position with a nose the carriage 8 in its right or left position (locked). After the gun barrel return (shot broken), the carriage 8 is now on the left side of the weapon and is held against the pressure of the spring 16 by the lever 10 in this position. The next drive cam 7 now runs from the right side into the groove 9 and takes the shutter 3 in its rear position. In this position, the cam 7 leaves the groove 9, whereby the shutter 3 is again stored by the drive 6 (2) and remains in its position.

Nach dem Zuführen einer neuen Patrone vor den Verschluss 3 betätigt beispielsweise ein Element des Zuführers (nicht näher dargestellt) den Hebel 14, wodurch die Arretierung des Schlittens 8 aufgehoben wird. Der Schlitten 8 wird dann durch die Feder 16 wieder auf die rechte Waffenseite verschoben, sodass der nächste Mitnehmernocken 7 den Verschluss 3 wieder nach vorne nimmt.After feeding a new cartridge in front of the shutter 3, for example, an element of the feeder (not shown in detail) actuates the lever 14, whereby the locking of the carriage 8 is released. The carriage 8 is then moved by the spring 16 back to the right side of the weapon, so that the next driver cam 7 takes the shutter 3 back to the front.

Erfolgt der Waffenrücklauf jedoch nicht, da der Schuss nicht gebrochen ist, verbleibt der Schlitten 8 in der vorderen Position an der rechten Waffenseite und der zweite bzw. nachfolgende Mitnehmernocken 7 kann den Verschluss 3 nicht entriegeln und mit zurücknehmen.However, if the weapon return is not because the shot is not broken, the carriage 8 remains in the forward position on the right side of the weapon and the second or subsequent driver cam 7 can not unlock the lock 3 and take back with.
