Description

Subject of the invention

The invention relates to a silencer for a handgun and a handgun with a silencer according to the invention.

Prior art and background of the invention

The term "handguns" means handguns, such as recoil loader weapons, gas pressure guns, pistols or the like. The invention is described using the example of a handgun, although the present invention is not limited thereto and can also be used in long weapons.

It is known to equip firearms with a silencer to reduce the noise emission emanating from the high-pressure and explosively expanding gases emitted during the shot from the muzzle. Such a silencer is for example from the DE41 01 171 A1 known.

Mufflers can be screwed on a screw thread at the front end of the gun barrel. Such a silencer is for example from the DE 42 31 183 C1 known.

In handguns with a fixed barrel of the muffler prepares only minor problems in terms of the self-loading function of the weapon.

In handguns with a moving barrel, maintaining the self-loading function of the weapon proves problematic. Because a muffler screwed onto the barrel or the cap increases the mass returning during the shot, as a result of which the return speed of the barrel and cap decreases. This can have the consequence that the self-loading function of the weapon either completely omitted or it can lead to malfunction, because about the ejection of the cartridge case and / or the supply of a new cartridge is incomplete and the weapon is not fully locked. This proves particularly problematic in firearms with a returning and tipping barrel, because here the muffler also still needs to be raised.

In practice, attempts have been made to solve this problem by lighter or smaller silencers. However, this has the disadvantage that with correspondingly lightweight silencers, the stability of the silencer decreases and that with smaller silencers, the damping effect is sometimes greatly reduced.

One solution to this problem is not rigidly connect the muffler and the gun barrel, but to arrange a so-called impulse generator between the muffler and the gun barrel, which is connected on the one hand to the muffler and the other with the gun barrel and the axial movement of the gun barrel relative to the muffler permits. With the pulse generator so the gun barrel is mechanically decoupled from the muffler, so that the self-loading function of the firearm is largely guaranteed despite the muffler.

However, the use of pulse generators has the disadvantage that they can easily contaminate and / or damage to the threads of the pulse generator can lead to impairment of the function of the firearm. In addition, the production of the pulse generator is relatively complex and expensive, which has a negative effect on the price of a muffler.
Both with mufflers that are screwed directly to the front end of the gun barrel, as well as silencers that are attached via a pulse at the front end of the gun barrel, it is disadvantageous that both the installation of the muffler and the dismantling of the muffler relatively much time takes up. Furthermore, it must always be ensured when screwing on the silencer that it is firmly screwed.

Object of the invention

The object of the invention is therefore, starting from the DE 41 01 171 A1 To provide mufflers for a handgun that allows easy, safe and quick assembly / disassembly of the muffler on the handgun and that can be used with handguns with a self-loading function or with a moving barrel without pulse generator, without the self-charging function is impaired ,

Detailed description of the invention

The muffler according to the invention described below has the significant advantage that it can be particularly simple, safe and fast, in particular fastened without screwing to the weapon or assembled and disassembled. Another important advantage of the muffler according to the invention is that it can also be used for handguns that have a movable barrel or a self-loading function, without having to use a pulse generator, while still maintaining the self-loading function of the handgun. Particularly advantageous is the use of the silencer according to the invention for handguns has proven that have a returning and tipping barrel.

Fig. 1 shows a silencer 10 according to the invention in a perspective view.

The muffler comprises in the embodiment shown here a substantially cuboid muffler housing 11 and a mounting rail 30th

The silencer housing has a rear end wall HE, which in the assembled state faces the weapon barrel of the firearm, and a front end wall VE opposite the rear end wall. Between the rear end wall and the front end wall, an upper wall 12 of the muffler housing is formed.

The muffler housing 11 may also have a different shape than the cuboid shape shown here. In particular, the muffler housing may have a substantially cylindrical shape, wherein even with a cylindrical muffler housing a mounting rail can be arranged according to the invention.

At the rear end or at the rear end wall HE of the muffler housing 11, a receiving opening 25 is provided, in which engages the front end of a gun barrel or can be brought into engagement. Inside and following the receiving opening 25 of the muffler housing 11, an axially or parallel to the longitudinal axis LA extending shot channel 20 is formed for a projectile.

The mounting rail 30 is disposed in the lower region of the muffler housing 11 and below the receiving opening 25 and extends in the longitudinal direction, ie, parallel to the longitudinal axis LA of the muffler housing 11 beyond the rear end wall HE addition. The mounting rail has in the shown here Embodiment of a silencer according to the invention a U-shaped profile. Longitudinal guides 32, which run parallel to the longitudinal axis LA of the muffler 10, are provided on the two side walls 31 of the U-shaped fastening rail 30.

In the embodiment of the fastening rail 30 shown in the perspective view of the muffler 10, each side wall 31 has an axially extending guide groove 32 which extends substantially over the entire length of the fastening rail 30.

With the mounting rail 30 of the muffler 10 is attached to a mounting rail of a firearm, so that a front end of the gun barrel comes into engagement with the receiving opening 25 of the muffler. The inner profile of the mounting rail 30 is adapted to the outer profile of the mounting rail of the firearm.

In a lower region of the fastening rail 30, a transverse channel 33 is formed, which runs essentially parallel to the transverse axis QA of the muffler 10. The transverse channel 33 is provided for receiving a locking or locking device, which is not shown here, for locking the muffler to the mounting rail of the firearm. With the locking or locking device ensures that the muffler 10 can not solve independently of the weapon.

At the bottom of the muffler 10, there is provided a mounting rail 34 which may be used to mount additional accessories, such as an additional handle or a tactical light. The mounting rail 34 extends in the embodiment of a silencer according to the invention shown here over the entire length of the muffler 10, ie from the rear end of the mounting rail 30 to the front end or to the front end wall VE of the muffler housing 10th

With the help of the mounting rail 30, the silencer according to the invention can be attached to a mounting rail of a handgun, wherein the longitudinal guides or guide joints 32 are brought into engagement with correspondingly designed longitudinal guides of the mounting rail of the handgun to the mounting rail of the handgun. With the help of arranged in the transverse channel 33 locking or locking device of the muffler can be locked to the handgun, so as to prevent an independent or unintentional axial movement of the muffler relative to the handgun. The locking or locking device can be configured as a passive or active locking or locking device.

In Fig. 1 Furthermore, two alternative profiles of a mounting rail 30 are shown.

In a first alternative, a groove of a dovetail guide can be provided at the bottom of the mounting rail, which can be brought into a corresponding with the groove spring of a dovetail guide of the mounting rail in engagement.

In a second alternative, a spring of a dovetail guide can be provided at the bottom of the mounting rail, which can be brought into a groove corresponding to the groove of a dovetail guide of the mounting rail in engagement.

Both the groove and the spring of the dovetail guides shown in the two alternatives extend in the axial direction and parallel to the longitudinal axis LA of the muffler.

In the Fig. 1 shown longitudinal guides 32 may extend over the entire length of the mounting rail. But it is also possible that the longitudinal guides extend only over a certain area, which ultimately of the specific embodiment of the corresponding longitudinal guides the mounting rail of the weapon depends. It is only important that the longitudinal guides 32 of the mounting rail correspond to corresponding longitudinal guides on the mounting rail of the handgun and allow movement of the muffler along the longitudinal axis LA relative to the handgun, provided that the muffler is not locked to the mounting rail.

With the silencer shown here is a particularly quick and easy installation of the muffler on a handgun possible. Because the muffler must be pushed only on the mounting rail of the handgun, which is provided below the barrel, until the front end of the barrel is brought into the receiving opening 25 of the muffler engaged or until the locking or locking device in the transverse channel 33rd Locked the muffler on the weapon or on the mounting rail of the weapon. Also, a particularly simple and quick disassembly of the muffler of the handgun is possible. It only needs the locking or locking device to be solved and the muffler can be deducted from the mounting rail of the handgun.

The fact that the muffler is not attached to the movable carriage / lock or on the movable barrel, but on the frame of the weapon or on the mounting rail of the weapon, the barrel can move independently of the muffler backwards, so that a self-charging function of the weapon is not affected by the muffler. Because the front end of the barrel into the receiving opening 25 of the muffler engages and because the muffler is not attached to the barrel, but attached to the frame of the weapon, no encoder must be provided. In particular, the silencer according to the invention can also be used in weapons with a so-called tipping barrel, whereby there is no pulse generator is necessary.

Fig. 2 shows a silencer according to the invention in a sectional view taken along a longitudinal axis LA of the muffler and a view of the rear end HE and a view of the front end VE of the muffler.

In figure (a) the Fig. 2 is a longitudinal section of the muffler 10 is shown, wherein the mounting rail in the axial direction, ie, parallel to the longitudinal axis LA, extends beyond the rear end and on the rear end wall HE of the muffler housing 11 addition. In an upper portion of the muffler housing 11, the receiving opening 25 is provided for receiving the front end of a gun barrel. Inside the muffler housing 11, a gas chamber 15 is formed.

In figure (b) the Fig. 2 a rear view of the muffler 10 is shown. Visible here is the configuration of the longitudinal guides or guide joints 32, which have a substantially wedge-shaped profile. Also visible here is the design of the provided on the underside of the muffler 10 mounting rail for receiving additional accessories on the underside of the muffler.

In figure (c) the Fig. 2 is a front view of the muffler 10 is shown. In the view shown here, the muffler is open and can be fitted with a cover as in Fig. 3 shown to be closed. Inside the muffler housing a structured insert 50 is arranged, with which the expansion of the explosively expanding gases can be controlled. The specific embodiment or form of the insert 50 is not relevant to the present invention and is shown here by way of example only. The muffler housing 11 has at the front end VE in the embodiment shown here, four holes 41 on which the in Fig. 3 shown cover can be screwed with mounting screws.

In an alternative embodiment of the invention, the muffler housing 11 may also be completed on the front side VE.

Fig. 3 shows in Figure (a) a cover 40 for closing or covering the front end VE of the muffler housing 11, provided that the muffler housing is not closed at the front end. The cover 40 has an orifice 23 through which the discharged projectile can escape. The cover 40 has boreholes 42 which correspond to the boreholes 41 of the silencer housing and via which the cover 40 can be secured to the silencer housing 11.

In figure (b) of Fig. 3 a section of the cover 40 along the section axis AA is shown. It can be seen here that the cover 40 has a substantially trough-shaped form, which has the advantage that by attaching the cover 40 to the muffler housing 11, the volume of the gas chamber 15 can be increased. With different deep trough-shaped covers different volumes of the gas chamber 15 can be realized.

Furthermore, structured inserts 50 of different lengths can thus be provided, as described with reference to FIG Fig. 5 are shown - are used.

In an alternative embodiment, the cover 40 may also be flat, i. not trough-shaped, be configured.

Fig. 4 shows an example of a structured insert 50 for a silencer 10 according to the invention.

In figure (a) the Fig. 4 is the insert 50 in a front view and in Figure (b) the Fig. 4 the insert 50 is shown in a sectional view along the longitudinal axis LA. The outer profile of the insert 50 substantially corresponds the inner profile of the gas chamber 15 of the muffler 10, so that the insert 50 can be inserted into the gas chamber 15 of the muffler 10 substantially flush with shape.
The insert 50 here has a number of fins 51, which are inclined at least partially obliquely to the rear and wherein some of the fins longitudinal bores 52 have. In the upper region of the fins, a shot channel 20 is formed, so that the projectile can pass unhindered through the insert. The structure, number and configuration of the fins 51 may be different from those in Fig. 4 differ significantly and depends essentially on the specific requirements of the damping properties of the muffler.
Fig. 5 shows a perspective view of a silencer 10 according to the invention in a sectional view taken along the longitudinal axis LA of the muffler. Also visible here is the silencer housing 11 with the cover 40 attached to the front end of the silencer housing 11 and with the insert 50 arranged inside the silencer housing 11, which has a number of slats 51 has to see. In the insert 50, a firing channel 20 is formed, which extends between the receiving opening 25 and the mouth opening 23 of the muffler or the silencer housing 11. Visible here is also arranged on the underside of the muffler 10 mounting rail 34 having a number of transverse ribs, wherein the transverse ribs are provided substantially for locking an attached to the mounting rail 34 accessories.
The silencer housing 11 and the mounting rail 30 protruding at the rear end or at the rear end wall HE of the silencer housing and extending parallel to the longitudinal axis LA are designed in one piece according to independent claim 1. Fig. 6 shows a development according to the invention of a silencer 10 according to the invention.
In figure (a) the Fig. 6 the rear area of the muffler 10 and the muffler housing 11 is shown in a sectional view. In figure (b) the
Fig. 6 a first embodiment of a cover plate 60 is shown and in Figure (c) of Fig. 6 a second embodiment of a cover plate 60 is shown.
At the rear end of the muffler housing 11, a cover plate 60 is provided, which is arranged or applied to the rear end wall HE of the muffler housing 11. The cover plate 60 is movable relative to the muffler housing 11 upwards. Furthermore, an opening or recess 61 is provided in the cover plate 60, which has substantially the same shape and the same size, preferably slightly larger, as the receiving opening 25 of the muffler. Through the opening 61 of the cover plate 60, the front end of the gun barrel can be brought into engagement with the receiving opening 25 of the muffler.
The use of the cover plate 60 shown here is particularly advantageous when the silencer according to the invention is used for firearms, which have a movable and rear tipping barrel. In such handguns, the front end of the gun barrel after dispensing a projectile from the receiving opening 25 of the muffler in the axial direction moved out. The rear end of the gun barrel is then tilted slightly downwards for the purpose of reloading, with the front end of the gun barrel tilting slightly upwards, resulting in a relatively large area of the receiving opening 25 being completely open and gases being able to escape through this opening.

The cover plate 60 is now provided to substantially prevent during loading that a larger portion of the receiving opening 25 is opened at an upwardly tilted front end of the barrel. The cover plate 60 is configured or arranged on the muffler housing 11 so that the cover plate 60 also moves upwards at an upwardly tilting front end of the gun barrel - synchronously with the front end of the barrel, so that the upwards moving cover plate 60, which closes by the upward tilting of the front end of the gun barrel resulting opening of the receiving opening 25 again. After loading, the front end of the gun barrel moves back down and into the receiving opening 25, wherein at the same time the Abdeckpatte 60 is moved back down.

Figure (b) the Fig. 6 shows a first embodiment of a cover plate 60. The cover plate 60 consists of a substantially flat plate having an opening or recess 61. The diameter of the opening or recess 61 substantially corresponds to the diameter of the receiving opening 25, so that the front end of a gun barrel can pass unhindered through the opening 61. In one embodiment of the cover plate 60, the edge of the opening 61 may be slightly bevelled.

At the rear or at the muffler housing 11 facing side of the cover plate 60 two perpendicular guide rails 62 are provided here, which are formed here as a groove of a dovetail guide. A first of the two guide rails 62 extends to the right of the opening 61 and a second of the two guide rails 62 extends to the left of the opening 61.

At the rear end wall HE of the muffler housing 11 corresponding guide rails are also provided, into which the guide rails 62 of the cover plate 60 are brought into engagement. For example, 11 may be provided at the rear end wall of the muffler housing two vertically extending and corresponding to the guide rails 62 of the cover plate 60 springs a dovetail. The cover plate 60 can then be moved up and down along the guide rails on the rear end wall of the muffler housing 11.

When shown in Figure (b) cover plate 60 emerging from the receiving opening 25 of the muffler and upwardly tilting front end of the gun barrel with the cover plate 60 so that essentially the lower half of the cover plate during loading the resulting opening of the receiving opening 25th closes.

In figure (c) the Fig. 6 an alternative embodiment of a cover plate 60 is shown. The cover plate 60 has at the upper end an edge-side semicircular recess 61, whose radius corresponds substantially to the radius of the receiving opening 25 of the muffler and the radius of the front end of the gun barrel. At the lower end of the cover plate 60, a spring element 64 is provided. The spring element 64 presses the cover plate from below against the gun barrel, so that when tilting the front end of the gun barrel up the cover plate 60 is also moved upward due to the spring force of the spring element 64 and thus resulting during the loading opening in the receiving opening 25th closes.

The embodiment of the cover plate 60 shown in Figure (c) has the advantage over the cover plate 60 shown in Figure (b) that not the gun barrel the cover plate must push upwards, but the spring element 64 pushes the cover plate upwards so that the gun barrel can tilt freely and without resistance upwards.

In the embodiment of a cover plate 60 shown in Figure (c), guide rails 62 may also be provided, as shown in Figure (b).

In the embodiment shown in Figure (b) can also be provided a spring element 64, with which a movement of the cover plate can be supported upwards.

In the cover plate 60 shown in Figure (c) a hole 63 is provided in a lower portion of the cover plate, which is formed here as a slot. The cover plate with the slot 63 is advantageous when the cover plate is used together with a muffler, as with reference to Fig. 7 and Fig. 9 is described. The design of the hole 63 as a slot is advantageous in order not to interrupt a passing through the hole 63 light beam during movement of the cover plate 60 upwards.

A corresponding hole or oblong hole 63 can also be provided in the case of a cover plate 60 as shown in FIG.

In figure (a) the Fig. 6 is to see a small gap between the cover plate 60 and the rear end wall of the muffler housing 11. However, it is advantageous if this gap is as small as possible in order to ensure the best possible coverage of the resulting during the charging opening of the receiving opening 25.

Fig. 7 shows an inventive development of a silencer 10 according to the invention, wherein in Figure (a) the rear end HE, in Figure (b) a sectional view along the longitudinal axis of the muffler and in Figure (c) is shown a perspective view of the muffler.

In the muffler 10 or in the muffler housing 11 here is a light channel 70 is arranged, which has an inlet opening 71 and an outlet opening 72 and which extends from the rear side wall to the front side wall of the muffler housing. The light channel 70 is designed here as a cylindrical channel through which a light beam can pass unhindered from the inlet opening 71 to the outlet opening 72.

One according to Fig. 7 configured muffler with a light channel 70 may be used, for example, when the handgun at the front end or below the gun barrel has a light source, such as a laser pointer. The laser pointer can be arranged approximately at the front end of the closing or return spring or on or in the spring sleeve of the closing or return spring of the weapon. A corresponding embodiment is with reference to Fig. 9 shown.

The light channel or light cylinder 70 may be made of a stable plastic, such as metal, which is air or pressure-tight attached to the front and rear end wall of the muffler housing. When using an insert 50, as related to Fig. 4 shown, the light channel or light cylinder 70 may be passed through the blades 51 of the insert. The fins 51 can then provide additional stability of the light channel 70.

In one embodiment of the invention, the light channel 70 may be provided as part of the insert 50 and be firmly connected to the insert 50, so that the light channel 70 can be removed together with the insert from the muffler housing 11. In this embodiment, only care must be taken that the light channel 70 is sealed air-tight or pressure-tight with respect to the gas chamber 15 after inserting the insert into the muffler housing 11.

Fig. 8 shows in Figure (a) the front end VE of a silencer according to the invention in a further embodiment in a sectional view.

At the in Fig. 8 shown silencer 10, a light source 80 is arranged in the front region or on the front end wall of the silencer housing, which is designed here as a laser diode. The luminous means 80 can be coupled to an electronics 81, with which the function or the operation of the luminous means 80 can be controlled. For example, the intensity of the laser diode can be controlled. The illuminant 80 and the electronics 81 are here coupled to a power supply 82, such as a battery.

In one embodiment of the invention, the lighting means 80, the electronics 81 and the power supply 82 are housed in a housing 83, wherein the lighting means 80 is disposed in an opening of the housing, as in Figure (b) of Fig. 8 shown. Preferably, the housing 83 is designed to be air-tight or pressure-tight, so that it can be arranged in the interior of the muffler housing 11. The muffler housing may have at the front end a receptacle 85 into which the housing 83 can be inserted and locked with the lighting means, the electronics and the power supply. Thereby, a modular lighting device is provided, which can be removed from the muffler if necessary or can be replaced by another lamp module.

If the receptacle 85 is designed to be air-tight or pressure-tight relative to the gas chamber 15, then the pressure-tight or airtight configuration of the housing 83 of the luminous means module can be dispensed with, which enables a simpler production of the luminous module.

Fig. 9 shows in Figure (a) a muffler 10 according to the invention, which is arranged or attached to a mounting rail 94 of a weapon 90. The gun barrel or the front end of the gun barrel 91 protrudes here into the receiving opening 25 of the muffler 10 inside, wherein the front end of the gun barrel 91, the air damper housing or the gas chamber of the muffler can preferably close air-tight or pressure-tight.

Below the gun barrel, a laser diode 80 is provided on the weapon, whose optical axis coincides with the longitudinal axis of the light channel 70.

At the front end of the weapon 90 a grain 92 is provided on the closure 93, wherein due to the particular shape of the muffler housing 11 no changes to the grain 92 are necessary when the weapon is used together with a muffler according to the invention.

Likewise, due to the particular form of the muffler housing according to the invention, the edge sight of the weapon can also be used when using the muffler.

Due to the particular design of the muffler, that is, the substantially cuboid shape of the muffler housing, it is possible to design the muffler housing 11 substantially shorter than in conventional cylindrical mufflers. This has the advantage that a holstering of the weapon is also possible with a mounted muffler.

In order to achieve the above advantages, it is advantageous if the outer profile of an upper portion OS of the muffler housing 11 of a muffler 10 has substantially the same outer profile as an upper portion OV of the closure 93 of a weapon 90, as described with reference to Figure (b ) of the Fig. 9 shown.

In the foregoing, a muffler has been described which is intended for the reduction of acoustic emission when a shot of a firearm is fired is provided. In a further inventive embodiment of the invention, the muffler can also be used as Duelsimulator.

Fig. 10 shows a further inventive embodiment of a muffler that can be used as a duel simulator, such as for training and / or training purposes, with bang or maneuver cartridges are used.

When using bang or maneuver cartridges in weapons with a self-loading function, the problem is that the bang or maneuver cartridges usually do not generate enough pressure during firing to build up the gun fast enough and / or far enough to the rear to move so that the spent cartridge case ejected and a new cartridge can be reloaded.

To solve this problem, the muffler 10 according to the invention is further developed in such a way that the muffler can be used as duel simulator. The muffler used as duel simulator is inventively designed such that it is ensured that even when using blast and / or maneuver cartridges the self-charging function of the weapon is completely upheld.

The basic construction of a muffler 10 used as a duel simulator corresponds essentially to that with reference to FIG Fig. 1 shown. The duel simulator thus comprises a muffler housing 11 and a mounting rail 30, wherein the mounting rail 30 is configured and attached to the muffler housing, as with reference to FIG Fig. 1 to Fig. 9 shown.

When using a muffler according to the invention as duel simulator, the muffler housing 11, however, be designed to be much shorter than that with respect to Fig. 1 to Fig. 9 shown muffler, because the volume of an expansion space for the expanding gases of the bang and / or Maneuver cartridges can or must be considerably smaller than the volume of the expansion space of a designated silencer used. The expansion space of a duel simulator should therefore be chosen to be smaller than the volume of an expansion space of a conventional muffler, to provide a sufficiently large recoil force or pressure for the return movement of the shutter.

In the interior of the muffler housing 11, an expansion space 16 is formed in the rear region, which adjoins the receiving opening 25 of the muffler housing 11, so that when firing a bang and / or maneuver the gases in the gun run 91 expanding gases can enter the expansion space 16. By the relatively small-sized expansion chamber 16 ensures that a pressure is built up by the penetrating into the expansion chamber gas, which ensures a reliable function of the self-charging function of the weapon.

The expansion chamber 16 may be connected to an overpressure channel 18, which is guided to the front end wall VE of the muffler housing 11. Via the overpressure channel 18, the expanding in the expansion space 16 gases are discharged to the outside, so that the pressure in the expansion space is reduced again. The overpressure channel 18 is preferably dimensioned so that despite the discharge of the gases from the expansion chamber 16 in the expansion chamber 16, a sufficiently large pressure can be built up, which is sufficient for the Selbstladefunktion of the weapon, and that the pressure in the expansion space to deliver the next shot reduced to a normal level.

The expansion space 16 of the duel simulator is pressure-tightly coupled to the gun barrel 91 after installation of the duel simulator on the weapon 90, so that as little gas as possible can escape between the expansion space and the weapon barrel. With such a pressure-tight coupling of the expansion space with the gun barrel can be dispensed with a reducer 19 for blast and / or maneuver cartridges.
In one embodiment of the Duelsimulators this can also be used together with a arranged at the mouth opening of the gun barrel 91 reducer 19. The reducer 19 is screwed into the mouth opening of the gun barrel 91 and screwed to the mouth of the gun barrel and ensures that enough pressure is built up in the gun barrel 91 after delivery of a shot to a proper function of the self-charging function of the weapon even with the use of bang - And / or maneuver cartridges to ensure.
The reducer has a substantially conical shape in the embodiment shown here. The reducer may also have any other suitable form for this purpose. The reducer 19 has a longitudinal channel 19a, through which the expanding in the gun barrel 91 gas can escape. When using the muffler according to the invention as duel simulator protrudes the front end of the reducer 19 into the receiving opening 25 of the duel simulator. Preferably, the reducer 19 seals the expansion space 16 pressure-tight against the receiving opening 25 from.

When using a muffler according to the invention as Duelsimulator together with a arranged on the weapon reducer 19 of the expansion space 16 is provided primarily to the fact that the emerging from the reducer 19 gases are discharged via the pressure relief channel 18. Nevertheless, the expansion space 16, when used in conjunction with a reducer 19, may be configured to achieve and achieve pressure necessary to maintain the self-loading function of the weapon such that the expansion space 16 performs substantially the same function as when using the dueling simulator without one arranged on the gun barrel reducer 19th

In the embodiment of the muffler used as duel simulator shown here, the expansion space 16 is arranged substantially coaxially to the gun barrel 91 and has substantially the same diameter as the weapon barrel 91.

In the housing 11 of the Duelsimulators here a receiving channel 21 is provided which is parallel to the longitudinal axis of the housing 11 and extending from the rear end wall HE to the front end wall VE of the housing 11. At the rear, i. in the rear end wall HE facing portion of the receiving channel 21 of the expansion space 16 described above is formed, wherein in the receiving channel 21, a bulkhead 17 is arranged, which pressure and gas-tight separates the rear portion of the receiving channel from the front portion of the receiving channel. The overpressure channel 18 opens into the rear region of the receiving channel 21, which forms the expansion space 16.

In a particular embodiment of the silencer according to the invention as Duelsimulator the bulkhead 17 can be moved in the longitudinal direction relative to the receiving channel 21 and locked to the receiving channel. Thus, expansion chambers of different sizes can be formed, so that the size of the expansion space 16 can optionally be adapted to the bang or maneuver cartridges used. For example, when using a bang cartridge, which generates too low a pressure for the proper functioning of the self-loading function of the weapon, the expansion space 16 are reduced accordingly, which amounts to an effective pressure increase.

The receiving channel 21 is configured here cylindrical. However, the receiving channel can also have a different shape, for example a rectangular or square profile. In particular, the front region of the receiving channel 21 may have a different profile than the rear region which forms the expansion space 16.

In the front region of the receiving channel 21, a power supply, such as a battery, a sensor unit and a laser diode are arranged. The battery 22 serves to supply power to the sensor unit 84 and the laser diode 80.

The sensor unit may comprise, for example, an acoustic sensor with which the firing of a blast or maneuver cartridge can be detected acoustically.

Alternatively, the sensor unit 84 may also include a pressure sensor with which a pressure increase in the expansion space 16, which is caused by the firing of a bomber cartridge, can be detected.

Furthermore, an evaluation or control device, not shown here, is arranged in the receiving channel 21, which is operatively coupled to the sensor unit 84. The evaluation or control unit is adapted to evaluate the sensor signal provided by the sensor unit 84 and to control the laser diode 80 as a function of the evaluation result. Preferably, the evaluation or control device is adapted to cause the laser diode 80 to emit a laser beam after detection of an emitted shot. In a very particular embodiment of the invention, an encoded laser beam is emitted by the laser diode after the detection of a firing. The encoded laser beam may include, for example, an identification number of the shooter and information about the weapon and / or ammunition type used.

The Duelsimulator can be modular, wherein the receiving channel 21 forms together with the pressure channel 18 a module that can be inserted into the housing 11. As a result, 11 different modules can be used in the housing, which are each adapted to different requirements.

The use of the muffler according to the invention as Duelsimulator, as with reference to Fig. 10 described, has the advantage that the duel simulator is not more on the gun barrel 91 must be screwed, but can be pushed to the mounting rail 94 of the weapon, which allows a particularly fast assembly and disassembly of Duelsimulators to or from the weapon.
