Description

Gegenstand der ErfindungSubject of the invention

Die Erfindung betrifft einen Schalldämpfer für eine Handfeuerwaffe, eine Handfeuerwaffe mit einem erfindungsgemäßen Schalldämpfer, sowie ein Verfahren zur Montage eines erfindungsgemäßen Schalldämpfers an einer Handfeuerwaffe.The invention relates to a silencer for a handgun, a handgun with a silencer according to the invention, and a method for mounting a silencer according to the invention on a handgun.

Hintergrund und Stand der TechnikBackground and state of the art

Unter dem Begriff "Handfeuerwaffen" werden Langwaffen verstanden, die im Gegensatz zu Faustfeuerwaffen eine Mündungsbremse besitzen.The term "handguns" long weapons are understood, which possess a muzzle brake in contrast to handguns.

Unter derartige Handfeuerwaffen fallen alle Waffenarten, wie z. B. Gewehre, Rückstoßladerwaffen oder Gasdruckladerwaffen, Repetiergewehre und Sturmgewehre.Among such small arms fall all types of weapons such. As rifles, recoil loader or gas-pressure guns, repeating rifles and assault rifles.

Die Erfindung wird am Beispiel eines Sturmgewehres der Marke "Steyr AUG 77/A" beschrieben, obwohl die vorliegende Erfindung hierauf nicht beschränkt ist.The invention is described using the example of an assault rifle of the brand "Steyr AUG 77 / A", although the present invention is not limited thereto.

Es ist bekannt, Handfeuerwaffen mit einem Schalldämpfer auszurüsten, ein solcher Schalldämpfer wird entweder auf das Ende des Waffenlaufes aufgeschraubt oder ist wie bei der MP5 SD oder der AWS fester Bestandteil der Waffe.It is known to equip handguns with a silencer, such a silencer is screwed either to the end of the gun barrel or is like the MP5 SD or the AWS integral part of the weapon.

Der Schalldämpfer reduziert ausschließlich die Schallemission, die von den beim Schuss aus der Laufinündung ausströmenden, unter hohem Druck stehenden und explosionsartig expandierenden Gasen ausgeht. Die mechanischen Geräusche einer eventuell vorhandenen Nachladeautomatik und der laute Geschossknall von Projektilen, die mit Überschallgeschwindigkeit abgefeuert werden, bleiben dagegen unbeeinflusst.The silencer reduces only the sound emission, which of the outflowing from the barrel inlet, under high pressure and exploding explosive gases. The mechanical noises of a possibly existing automatic recharging mechanism and the loud projectile blast of projectiles which are fired at supersonic speed, however, remain unaffected.

Weiterhin unterdrückt der Schalldämpfer auch das Mündungsfeuer, so dass Vorteile bei Nachteinsätzen unter Benutzung von Nachtsichtgeräten gegeben sind.Furthermore, the silencer also suppresses the muzzle flash, so that there are advantages in night operations using night vision devices.

Beispielsweise ist es aus der DE 10 2005 005 585 A1 , der DE 198 15 467 A1 oder der DE 42 31 183 C1 bekannt, einen Schalldämpfer auf das Schraubgewinde am vorderen Ende des Waffenlaufes der Waffe zu schrauben.For example, it is from the DE 10 2005 005 585 A1 , of the DE 198 15 467 A1 or the DE 42 31 183 C1 known to screw a muffler on the screw thread at the front end of the gun barrel of the weapon.

Eine Vielzahl von Handfeuerwaffen werden mit einer Mündungsbremse ausgestattet, wie insbesondere beim Sturmgewehr "Steyr AUG 77" bekannt.A variety of handguns are equipped with a muzzle brake, as in particular in the assault rifle "Steyr AUG 77" known.

Eine Mündungsbremse ist eine Vorrichtung am Lauf derartiger Feuerwaffen, welche die Energie der Verbrennungsgase nutzt, um den Rückstoß des Laufes zu mindern. Mündungsbremsen kommen vorwiegend an Maschinenkanonen und Geschützen, seltener jedoch an Handfeuerwaffen zum Einsatz.A muzzle brake is a device on the barrel of such firearms that uses the energy of the combustion gases to reduce the recoil of the barrel. Muzzle brakes are mainly used on machine guns and guns, but more rarely on handguns.

Die Mündungsbremse besteht in an sich bekannter Weise aus einer oder mehreren vor der Rohrmündung montierten Prallflächen, die fest mit dem Rohr verbunden sind. Diese Prallflächen haben eine Öffnung für den Durchtritt des Geschosses, deren Durchmesser das 1,1-fache des Geschosskalibers beträgt.The muzzle brake consists in a conventional manner of one or more before the muzzle mounted baffles, which are firmly connected to the pipe. These baffles have an opening for the passage of the projectile whose diameter is 1.1 times the bullet caliber.

Unmittelbar, nachdem das Geschoss das Rohr verlassen hat, treten die unter Druck stehenden Verbrennungsgase des Treibsatzes aus dem Rohr aus und treffen dabei teilweise auf die Prallflächen der Mündungsbremse. Durch die Prallflächen werden sie rechtwinklig oder sogar leicht nach hinten abgelenkt und übertragen dabei einen Teil ihrer Energie auf die Mündungsbremse und damit auf den Lauf. Die in Schussrichtung wirkende Energie der Verbrennungsgase wirkt durch das Auftreffen auf der Mündungsbremse den nach hinten gerichteten Rückstoß entgegen und reduziert diesen.Immediately after the projectile has left the tube, the pressurized combustion gases of the propellant exiting the tube and thereby partially hit the baffles of the muzzle brake. The baffles deflect them at right angles or even slightly backwards, transferring some of their energy to the muzzle brake and thus to the barrel. The energy of the combustion gases acting in the firing direction acts through the Upon encountering the muzzle brake, it counteracts the rearward recoil and reduces it.

Aus der US 7,661,349 B1 eine Handfeuerwaffe mit einer am Waffenlauf befestigten Mündungsbremse bekannt, wobei über Verbindungsmittel ein Schalldämpfer lösbar mit der Mündungsbremse verbindbar ist. Die den Außenmantel des Schalldämpfers bildende Mantelhülse ist mit einem inneren, längsaxial ausgerichteten Rohrmantel verbunden.From the US Pat. No. 7,661,349 B1 a handgun with a muzzle brake attached to the gun barrel, wherein a silencer is detachably connectable to the muzzle brake via connecting means. The outer jacket of the muffler forming jacket sleeve is connected to an inner, longitudinally axially aligned pipe jacket.

Aufgabe der ErfindungObject of the invention

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Handfeuerwaffe mit Mündungsbremse der eingangs genannten Art so weiterzubilden, um eine alternative Befestigungsmöglichkeit eines Schalldämpfers an einer Mündungsbremse bereitzustellen.The invention is therefore the object of developing a handgun with muzzle brake of the type mentioned so as to provide an alternative mounting option of a muffler on a muzzle brake.

Erfindungsgemäße LösungInventive solution

Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Anspruches 1 gekennzeichnet.To solve the problem, the invention is characterized by the technical teaching of claim 1.

Wesentliches Merkmal der Erfindung ist, dass nunmehr die am Waffenlauf befestigte Mündungsbremse über eine Schraubverbindung mit dem Schalldämpfer verbindbar ist, wobei die Mündungsbremse im Bereich ihres vorderen Endes einen Ringansatz aufweist, der ein Innengewinde ausbildet, welches mit einem Außengewinde einer Gewindehülse des Schalldämpfers als Schraubverbindung zusammenwirkt und wobei die den Außenmantel des Schalldämpfers bildende Mantelhülse mit radialen Verbindungswänden mit einem inneren, längsaxial ausgerichteten Rohrmantel verbunden ist, an dessen vorderen Ende die Gewindehülse mit dem in axialer Richtung weisenden Außengewinde angeordnet ist.An essential feature of the invention is that now attached to the gun barrel muzzle brake is connected via a screw with the muffler, the muzzle brake has a ring approach in the region of its front end, which forms an internal thread which cooperates with an external thread of a threaded sleeve of the muffler as a screw connection and wherein the outer jacket of the muffler forming jacket sleeve is connected with radial connecting walls with an inner, longitudinally axially aligned pipe jacket, at the front end of the threaded sleeve is arranged with the pointing in the axial direction of external thread.

Dadurch wird eine leicht lösbare Verbindung zwischen der Mündungsbremse und einem darauf aufzusetzenden Schalldämpfer über eine erfindungsgemäße Schraubverbindung ermöglicht.As a result, an easily detachable connection between the muzzle brake and a muffler to be placed on it via a screw connection according to the invention is made possible.

In einer vorteilhaften Ausgestaltung der Erfindung umschließt der innere Rohrmantel des Schalldämpfers die Mündungsbremse vollständig.In an advantageous embodiment of the invention, the inner tube shell of the muffler completely encloses the muzzle brake.

Diese im Schalldämpfer etwa im mittleren Bereich angeordnete Gewindehülse mit Außengewinde wirkt mit dem Innengewinde am vorderen Ende der Mündungsbremse zusammen und bildet die erfindungsgemäße Schraubverbindung.This arranged in the muffler approximately in the central region threaded sleeve with external thread cooperates with the internal thread at the front end of the muzzle brake and forms the screw according to the invention.

Damit besteht der Vorteil, dass die Mündungsbremse in einer langgestreckten Längsbohrung des Schalldämpfers aufgenommen wird, wodurch eine verkippungsfreie Führung und Befestigung der Mündungsbremse im Innenraum des Schalldämpfers gewährleistet ist.This has the advantage that the muzzle brake is received in an elongated longitudinal bore of the muffler, whereby a tilt-free guidance and attachment of the muzzle brake is ensured in the interior of the muffler.

Weiterer Vorteil ist, dass im Bereich dieser Längsbohrung die aus der Mündungsbremse entweichenden Explosionsgase in eine Anzahl von gleichmäßig verteilten am Umfang angeordneten Querbohrungen aufgenommen wird, die luftschlüssig mit einem am Außenumfang der Längsbohrung angeordneten Expansionskammer verbunden sind, welche diese Explosionsgase aufnimmt.Another advantage is that, in the region of this longitudinal bore, the explosion gases escaping from the muzzle brake are received in a number of uniformly distributed circumferential bores which are connected in an air-tight manner to an expansion chamber arranged on the outer circumference of the longitudinal bore, which receives these explosive gases.

Ferner ist wesentlich, dass diese Explosionskammer luftschlüssig mit der sich in axialer Richtung daran anschließenden, weiteren Gaskammer verbunden ist und die luftschlüssige Verbindung dadurch erfolgt, dass in der Verbindungswand, welche die Expansionskammer von der sich in axialer Richtung anschließenden Gaskammer trennt, Längsbohrungen angeordnet sind.Furthermore, it is essential that this explosion chamber is connected in an air-tight manner to the further gas chamber adjoining it in the axial direction and the air-tight connection takes place in that longitudinal bores are arranged in the connecting wall which separates the expansion chamber from the gas chamber adjoining in the axial direction.

Dadurch müssen die in der Expansionskammer gesammelten Gase unter Entspannung durch die Längsbohrungen in der Verbindungswand in axialer Richtung des Schalldämpfers hindurchströmen und strömen danach in der sich daran anschließenden Gaskammer ein.As a result, the gases collected in the expansion chamber must flow under relaxation through the longitudinal bores in the connecting wall in the axial direction of the muffler and then flow into the adjoining gas chamber.

Hierbei wird es bevorzugt, wenn in der Gaskammer eine Anzahl von zueinander parallelen und einen gegenseitigen Abstand ausbildenden Ringlamellen angeordnet sind, die zwischen sich Expansionsräume ausbilden.Here, it is preferred if in the gas chamber, a number of mutually parallel and a mutual distance forming annular lamellae are arranged, which form between them expansion spaces.

Damit werden eine ausgezeichnete Dämpfungswirkung und eine Entstörung der dort eintretenden Explosionsgase erreicht.Thus, an excellent damping effect and a suppression of the entering there explosion gases are achieved.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

Detaillierte Beschreibung der ErfindungDetailed description of the invention

In Fig. 1 ist ein Sturmgewehr als Rückstoßlader-Feuerwaffe 1 dargestellt, auf dessen Waffenlauf 3 eine Mündungsbremse 4 befestigt ist, die mit einem Schalldämpfer 2 verbunden ist. Die Mündungsbremse 4 kann fest mit dem Waffenlauf 3 verbunden sein. Alternativ kann die Mündungsbremse 4 auch lösbar, etwa über ein Schraubgewinde mit dem Waffenlauf 3 verbunden sein.In Fig. 1 an assault rifle is shown as a recoil loader firearm 1, on whose gun barrel 3 a muzzle brake 4 is attached, which is connected to a muffler 2. The muzzle brake 4 can be firmly connected to the gun barrel 3. Alternatively, the muzzle brake 4 can also be releasably connected, for example via a screw thread with the gun barrel 3.

Aus Fig. 2 und Fig. 3 gehen die weiteren Einzelheiten der Befestigung hervor.Out Fig. 2 and Fig. 3 go out the further details of the attachment.

Wie aus Fig. 2 entnehmbar, ist an der Vorderseite des Waffenlaufes 3 eine Mündungsbremse 4 angeordnet, wobei der Waffenlauf 3 einen Gewindeansatz 5 mit einem Außengewinde ausbildet, auf dem die Mündungsbremse 4 aufgeschraubt ist.How out Fig. 2 removed, a muzzle brake 4 is arranged at the front of the gun barrel 3, wherein the gun barrel 3 forms a threaded extension 5 with an external thread on which the muzzle brake 4 is screwed.

Die Abdichtung der Mündungsbremse nach hinten erfolgt über einen Sprengring 6, und es sind ferner noch Ringnuten 7 vorhanden, in die geeignete Dichtungsringe eingelegt werden können.The sealing of the muzzle brake to the rear via a snap ring 6, and there are also still annular grooves 7 available, can be inserted into the appropriate sealing rings.

Die Mündungsbremse 4 bildet im vorderen Bereich eine Reihe von in Umfangsrichtung gleichmäßig verteilt angeordneten Schlitzen 9, durch welche die Explosionsgase radial nach außen entweichen können. Anstelle der Schlitze 9, kann die Mündungsbremse auch eine Anzahl von Bohrungen aufweisen, durch welche die Explosionsgase ebenfalls radial nach außen entweichen können.The muzzle brake 4 forms in the front region a series of evenly distributed circumferentially slits 9, through which the explosion gases can escape radially outward. Instead of the slots 9, the muzzle brake may also have a number of holes through which the explosive gases can also escape radially outward.

Ferner ist das vordere Ende der Mündungsbremse 4 durch einen Ringansatz 10 ausgebildet, der einen Ringanschlag 15 bildet und der ein Innengewinde 12 als Teil der erfindungsgemäßen Gewindeverbindung 11 aufweist.Further, the front end of the muzzle brake 4 is formed by a ring lug 10 which forms an annular stop 15 and which has an internal thread 12 as part of the threaded connection 11 according to the invention.

Die Mündungsbremse 4 wird somit in die in axialer Richtung sich erstreckende Aufnahmebohrung 29 des Schalldämpfers 2 eingesteckt, wodurch eine ausgezeichnete verkippungsfreie Führung gemäß Fig. 2 gewährleistet wird.The muzzle brake 4 is thus inserted into the axially extending receiving bore 29 of the muffler 2, whereby an excellent tilt-free guide according to Fig. 2 is guaranteed.

Die Längsbohrung 8, welche den Schusskanal im Waffenlauf 3 ausbildet, mündet also in den Innenraum der Mündungsbremse 4 gemäß Fig. 2.The longitudinal bore 8, which forms the firing channel in the weapon barrel 3, thus discharges into the interior of the muzzle brake 4 Fig. 2 ,

Der Schalldämpfer 2 wird nun auf die Mündungsbremse 4 aufgesetzt und aufgeschoben, bis das Außengewinde 13 einer im Innenraum des Schalldämpfers 2 angeordneten Gewindehülse 14 zur Anlage an dem Innengewinde 12 der Mündungsbremse 4 gelangt.The muffler 2 is now placed on the muzzle brake 4 and postponed until the external thread 13 of a arranged in the interior of the muffler 2 threaded sleeve 14 comes to rest against the internal thread 12 of the muzzle brake 4.

Es genügen dann nur lediglich etwa 8 Umdrehungen des Schalldämpfers 2 auf der Mündungsbremse 4, um dafür zu sorgen, dass der Ringansatz 10 der Mündungsbremse in den Aufnahmeraum 21 des Schalldämpfers im Bereich der Verbindungswand 20 zur Anlage kommt und gleichzeitig der Ringanschlag 15 ein weiteres Einschrauben verhindert.It then suffice only about 8 revolutions of the muffler 2 on the muzzle brake 4, to ensure that the annular shoulder 10 of the muzzle brake in the receiving space 21 of the muffler in the region of the connecting wall 20 comes to rest and at the same time the ring stop 15 prevents further screwing.

Die erfindungsgemäße Gewindehülse 14 ist Teil des Innenraumes des Schalldämpfers 2 und ist mit einem im Schalldämpferinnenraum angeordneten Rohrmantel 16 über eine Verbindungswand 20 verbunden.The threaded sleeve 14 according to the invention is part of the interior of the muffler 2 and is connected to a arranged in the muffler interior pipe jacket 16 via a connecting wall 20.

Die Verbindungswand 20 ihrerseits ist werkstoffeinstückig mit der Gewindehülse 14 ausgeformt.The connecting wall 20 in turn is material integral with the threaded sleeve 14 formed.

Ferner setzt sich die Verbindungswand 20 bevorzugt werkstoffeinstückig über eine weitere Verbindungswand 18 zum Innenumfang der Mantelhülse 28 des Schalldämpfers 2 fort.Furthermore, the connecting wall 20 is preferably made of material in one piece via a further connecting wall 18 to the inner circumference of the jacket sleeve 28 of the muffler 2 on.

Der im Durchmesser gegenüber der äußeren Mantelhülse 28 verminderte Rohrmantel 16 ist an seinem hinteren Ende über ein Hülsenteil 27 bevorzugt werkstoffeinstückig mit der Mantelhülse 28 verbunden.The tube jacket 16, which is reduced in diameter relative to the outer jacket sleeve 28, is preferably materially connected to the jacket sleeve 28 at its rear end via a sleeve part 27.

Der Schalldämpfer 2 kann auch zweiteilig ausgestaltet sein, wobei ein erster Teil durch die Gewindehülse 14, die Verbindungswand 20 und den Rohrmantel 16 gebildet wird, und der zweite Teil durch die Mantelhülse 28, die Verbindungswand 18 und dem Hülsenteil 27 gebildet wird. Die Verbindung des ersten Teils mit dem zweiten Teil kann über ein Schraubgewinde im Bereich des Hülsenteils 27 erfolgen, wobei am Hülsenteil 27 ein Innengewinde und am hinteren Ende des Rohrmantels 16 ein mit dem Innengewinde korrespondierendes Außengewinde vorgesehen sind. Bei der zweiteiligen Ausgestaltung ist es möglich zunächst das erste Teil an der Mündungsbremse 4 anzubringen und anschließend das zweite Teil auf das erste Teil aufzuschrauben. Zudem lässt sich bei einer zweitteiligen Ausgestaltung die Herstellung des erfindungsgemäßen Schalldämpfers vereinfachen.The muffler 2 may also be configured in two parts, wherein a first part is formed by the threaded sleeve 14, the connecting wall 20 and the tube jacket 16, and the second part is formed by the jacket sleeve 28, the connecting wall 18 and the sleeve part 27. The connection of the first part with the second part can take place via a screw thread in the region of the sleeve part 27, wherein the sleeve part 27, an internal thread and at the rear end of the tubular jacket 16 are provided with an external thread corresponding to the internal thread. In the two-part embodiment, it is first possible to attach the first part to the muzzle brake 4 and then screw the second part onto the first part. In addition, in a two-part embodiment, the production of the silencer according to the invention can be simplified.

Bei der zweiteiligen Ausgestaltung des erfindungsgemäßen Schalldämpfers können für beide Teile unterschiedliche Materialen vorgesehen sein. Das erste Teil kann beispielsweise aus einem Metall gefertigt sein. Das zweite Teil kann beispielsweise aus einem Verbundwerkstoff etwa kohlenstofffaserverstärkter Kunststoff hergestellt sein. Damit kann einerseits das Gewicht des Schalldämpfers erheblich reduziert werden, ohne die Stabilität negativ zu beeinflussen.In the two-part embodiment of the silencer according to the invention different materials can be provided for both parts. The first part may be made of a metal, for example. The second part may for example be made of a composite material such as carbon fiber reinforced plastic. Thus, on the one hand the weight of the muffler can be significantly reduced without negatively affecting the stability.

Die zweiteilige Ausgestaltung der Schalldämpfers ist bei allen der hier gezeigten Ausführungsformen der Erfindung möglich.The two-part embodiment of the muffler is possible in all of the embodiments of the invention shown here.

Bei der Entstehung von Explosionsgasen direkt an der Mündung 35 des Gewehrlaufes 3 treten diese Explosionsgase in den Innenraum 34 der Mündungsbremse 4 ein und entweichen über die Schlitze 9 bzw. über die Bohrungen in radialer Richtung über eine Anzahl von Querbohrungen 17, welche den Rohrmantel 16 durchbrechen.In the formation of explosive gases directly at the mouth 35 of the gun barrel 3, these explosive gases enter the interior 34 of the muzzle brake 4 and escape through the slots 9 and over the holes in the radial direction over a number of transverse holes 17 which break through the tube shell 16 ,

Damit erfolgt eine Richtungsumkehr der Explosionsgase, die in Pfeilrichtung 32 nach dem Einströmen in die Expansionskammer 26 umgelenkt werden und in Pfeilrichtung 33 durch zugeordnete Längsbohrungen 19 in der radialen Verbindungswand 18 hindurchströmen.This results in a reversal of the direction of the explosion gases, which are deflected in the direction of arrow 32 after flowing into the expansion chamber 26 and flow in the direction of arrow 33 through associated longitudinal holes 19 in the radial connecting wall 18.

Sie gelangen somit in Pfeilrichtung 33 in die sich luftschlüssig an die Expansionskammer 26 anschließende Gaskammer 25.They thus arrive in the direction of arrow 33 in the air-tightly adjoining the expansion chamber 26 gas chamber 25th

Der Schusskanal 22 durchsetzt diese Gaskammer 25 und mündet in die Mündungsöffnung 23 des Schalldämpfers 2, wo das Geschoss den Schalldämpfer in Pfeilrichtung 24 verlässt.The shot channel 22 passes through this gas chamber 25 and opens into the mouth opening 23 of the muffler 2, where the projectile leaves the muffler in the direction of arrow 24.

Die Schlitze 9 bzw. die Bohrungen in der Mündungsbremse 4 können zumindest teilweise mit den Querbohrungen 17 Schalldämpfers korrespondieren bzw. fluchten, sodass ein im Wesentlichen ungehindertes Entweichen der Explosionsgase aus dem Innenraum 34 der Mündungsbremse 4 ermöglicht wird.The slots 9 or the holes in the muzzle brake 4 can at least partially correspond to the transverse bores 17 muffler or aligned, so that a substantially unhindered escape of the explosive gases from the interior 34 of the muzzle brake 4 is made possible.

Im Ausführungsbeispiel nach Fig. 2 ist nicht angegeben, in welcher Weise die Gaskammer 25 ausgebildet ist.In the embodiment according to Fig. 2 is not specified, in which way the gas chamber 25 is formed.

Die dort angeordneten Einbauten können in verschiedenen Formgebungen ausgebildet sein.The internals arranged there can be formed in different shapes.

Als bevorzugtes Beispiel ist ein Einbau von Ringlamellen 30 gemäß Fig. 3 dargestellt.As a preferred example, an installation of annular blades 30 according to Fig. 3 shown.

Diese Ringlamellen sind etwa halbrund geformte Wandkörper, die in ihrem Mittenbereich durch den Schusskanal 22 durchsetzt sind.These annular lamellae are approximately semicircular shaped wall bodies, which are penetrated in their middle region by the firing channel 22.

Der Schusskanal 22 ist hierbei als Bohrung durch die Ringlamellen 30 ausgebildet.The firing channel 22 is in this case formed as a bore through the annular blades 30.

Jede Ringlamelle 30 bildet in Verbindung mit der benachbarten und im Abstand zueinander angeordneten, weiteren Ringlamelle einen Expansionsraum 31, so dass eine Anzahl von Expansionsräumen 31 in der Gaskammer 25 ausgebildet sind, welche zu einer Entstörung und Beruhigung der Explosionsgase führen.Each ring blade 30 forms an expansion space 31 in conjunction with the adjacent and spaced-apart, further annular lamella, so that a number of expansion spaces 31 are formed in the gas chamber 25, which lead to a suppression and calming of the explosion gases.

Mit der Verwendung des erfindungsgemäßen Schalldämpfers ist es nun nicht mehr notwendig, die Mündungsbremse vor Verwendung des Schalldämpfers abzubauen, sondern mit der vorliegenden Erfindung wird erstmals die Möglichkeit geboten, die Mündungsbremse unmittelbar im Innenraum des Schalldämpfers über eine Schraubverbindung zu befestigen.With the use of the muffler according to the invention, it is no longer necessary to reduce the muzzle brake before using the muffler, but with the present invention, the opportunity is offered for the first time to attach the muzzle brake directly in the interior of the muffler via a screw connection.

Mit der vorliegenden Erfindung ist es auch möglich einen Schießbecher, etwa einen Granatschießbecher, einen Zusatzlauf oder einen Laseraufsatz derart auszugestalten, dass dieser lösbar an der Mündungsbremse befestigt werden kann.With the present invention, it is also possible to design a shooting cup, such as a garnet shooting cup, an additional barrel or a laser attachment in such a way that it can be detachably fastened to the muzzle brake.
