Definitions
- the present invention relates to a muffler system for a firearm, with a montier on the barrel of the firearm Baren jacket tube, in which coaxially a first muffler is arranged with an axial passage opening.
- Silencers of this type are known for example from US 2013/0168181 Al or US 2014/0231168 Al and constructed from egg nem stack of Ablenktmün.
- the Ablenktöpfe each have a running side tapered, from the bullet hole axially interspersed inflow and - either due to their mutual distances (US 2013/0168181 Al) or due to breakthroughs in the pot walls (US 2014/0231168 Al) - radial gas passages.
- the radial gas passages are pocket-like closed by the surrounding jacket tube, so that in succession shot through a sequence of gas collecting pockets ("Sackgas sen”), which progressively degrade the pressure exiting the barrel mouth gas pressure to dampen the firing bang
- the gas produced by the muffler backpresses the weapon, which in self-loading weapons can lead to increased wear on the material and, in the worst case, destruction of the weapon, as well as increased gas pressure from the patron ejection window, which severely impairs the shooter
- the protective equipment of the shooter so that appropriate protective equipment is erforder Lich.
- the known muffler constructions have the disadvantage over that in the dead ends of the successive Over time, more and more powder residues are deposited in the following pressure reduction pockets, so that the silencer "grows" and the damping performance gets worse and worse until the silencer becomes totally useless.
- the invention has for its object to provide a muffler system with improved damping performance, lower gas backpressure and extended usability.
- a muffler system for a firearm with a montier on the barrel of the firearm Baren jacket tube, in which coaxially a first muffler is arranged with an axial passage opening, which is characterized in that the first muffler to form an intermediate first annulus in Casing tube is arranged and at its running end one of its bullet hole interspersed, with axial distance to the running lie ing inflow cone to diverging from the barrel diverging from passing gases in the annulus, which is provided with baffles and a downstream gas outlet.
- the silencer system according to the invention results in a technically fluid parallel connection between an internal (“first") silencer and a coaxial around this built on another silencer, the baffles in the first Annular space is formed between the first muffler and the surrounding jacket tube.
- the Anströmkegel at the running or a gear-side end of the first muffler acts as a distributor for the emerging from the muzzle gases: The exiting directly in extension of the barrel gases enter through the bullet hole of the Anströmkegels in the first muffler, while from the axis diverging Ga se be directed by the Anströmkegel in the annulus and the baffle silencers located there.
- the parallel connection of an internal, for example in chamber construction constructed silencer and a dead-end baffled muffler reduces the backwater for the weapon and the shooter.
- the Axi alabstand the Anströmkegels from the barrel erects a large-volume pressure reduction chamber in the jacket tube, which on the one hand represents the distributor for the parallel connection of the inner first silencer and outer baffle silencer and on the other hand causes a first pressure reduction of the powder gases.
- inner first silencer and outer baffle silencer results in a very compact construction of short overall length with high damping power.
- gas flow in the outer bag cools the inner first silencer without baffles. Since the radially outer portion of the powder gas jet no longer enters the inner first muffler, this grows less, while the risk of misleading the baffles of the outer muffler is reduced due to their flow, so that the life of the entire Silencer system is extended compared to conventional constructions.
- the baffles of the outer sound damper constructed in the annulus may be formed in any manner known in the art, such as meandering baffles, ribs, wings, etc.
- the baffles are axially spaced one behind the other in the circumferential direction offset baffles formed, preferably ring sector-shaped Ablenkble surface. This results in a meandering gas flow in the annulus along the first muffler, which sufficiently binds the pressure reduction with good flushing and cooling effect ver.
- the inner first muffler can be constructed in any manner known in the art, also as a "classical" chamber muffler
- the first muffler comprises, in particular, a stack of baffles, each of which has a barrel side, The stack of Ablenktmün results along the bullet hole a sequence of each lying around the shot opening through pressure reduction chambers to which the au .midos of the pressure wave are respectively derived.

- a sleeve enrollmentnom men which is located at an axial distance from the first silencer, wherein the second annulus is also provided with baffles and preferably a downstream gas outlet.
- the second baffle muffler in the second annulus is Strömungstech also the other two mufflers, namely the first coaxial inner muffler and the first outer baffle muffler, connected in parallel. The deflection of the powder gas jet in the "overbarrel" lying second baffle muffler, i.e. against the firing direction, reduces the recoil of the weapon.
- the second baffle muffler can also be designed without a gas outlet, for example if escape of gases in the vicinity of the face of the shooter is to be avoided. If desired, but can also here a gas outlet, in particular in the form of axial normal Auslassöff openings in the jacket tube, are provided to achieve a flushing.
- the sleeve is preferably slidable onto the barrel and, at its end facing the first muffler, has a thread for anchoring to the barrel, so that the "overbar" Rel "part with the second baffle silencer against the run can swing freely.
- the muffler system of the invention comprises four fluidly connected mutually parallel muffler, u.zw.
- the second inner muffler may be formed in any manner known in the art.
- the second Schalldämp fer includes at least one or more, ie a stack of Ablenktöpfen, so that the same components can be used as for the first silencer. This results in a further modularization of the muffler system.
- the jacket tube can optionally between the first muffler and the sleeve or between the first and the second silencer a - preferably kege lige - Partition with a central opening included.
- the additional partition deflects the diverging from the barrel austre border part of the gases directly to the second baffle silencer out to.
