Description

The invention relates to a silencer for mounting on a weapon barrel, having a silencer housing for completely enclosing the weapon barrel at least in sections.

In the field of weapon technology, silencers, also called muzzle signature reducers, are devices arranged at the muzzle of a gun barrel of the firearm to reduce noise emissions and muzzle flash. Furthermore, silencers can also reduce recoil when the shot is fired, which, together with the mass of the silencer, reduces the firearm's muzzle roll. Furthermore, the precision of long guns is increased, since silencers have a positive, physical influence on the (propellant/combustion) gases that follow the bullet. In addition, a silencer changes the sound of the muzzle blast.

In particular, silencers reduce the volume of the muzzle blast and thus reduce the risk of hearing damage in hunters, beaters and dogs, for example. In contrast to hearing protectors, silencers do not restrict three-dimensional hearing.

Such silencers are often designed as barrel attachments that can be screwed on. The silencers here have an internal thread which can be screwed onto a corresponding external thread of a weapon barrel (muzzle thread) on the end face (muzzle side). In order to ensure guidance and attachment that is as free of tilting as possible, these threads are often formed with a fine thread. For example, if dirt gets to this during a hunt fine thread, this makes it more difficult or even impossible to attach the silencer.

The invention is based on the object of specifying a particularly suitable silencer for mounting on a gun barrel. In particular, a simple and cost-reduced assembly should also be made possible on gun barrels without a muzzle thread.

The object is achieved according to the invention with the features of claim 1. Advantageous refinements and developments are the subject of the dependent claims.

The silencer according to the invention is intended for mounting on a gun barrel and is suitable and set up for this. The silencer is preferably designed as a barrel attachment that can be placed on a gun barrel or a muzzle of a gun, in particular a hand-held gun, preferably a hunting rifle.

The silencer has a silencer housing which, in the assembled state, completely encloses the weapon barrel at least in sections. In this case, the silencer housing has an integrated jacket tube, which preferably encloses the weapon barrel in the assembled state. A muzzle brake is accommodated in the silencer housing, which keeps the jacket tube centered in the silencer housing. In this case, the muzzle brake is provided and set up to use the energy of the combustion gases (propellant gases) produced when a shot is fired in order to reduce the recoil of the firearm. The silencer also has a device for deflecting and/or cooling the gases produced when a shot is fired, as a result of which the muzzle blast and muzzle flash are reduced.

According to the invention, the silencer has a clamping device for positively and/or non-positively locking the weapon barrel. In other words is a non-destructive clamp attachment of the silencer on the gun barrel is provided, so the gun barrel is clamped by the clamping device. This makes it possible to attach the silencer to a gun barrel without a muzzle thread. A particularly suitable silencer is thus realized.

The conjunction “and/or” is to be understood here and in the following in such a way that the features linked by means of this conjunction can be designed both together and as alternatives to one another.

A "positive fit" or a "positive connection" between at least two parts connected to one another is understood here and in the following in particular to mean that the parts connected to one another are held together at least in one direction by direct interlocking of the contours of the parts themselves or by indirect interlocking via an additional connector. The "blocking" of a mutual movement in this direction is therefore due to the shape.

A “positive connection” or a “positive connection” between at least two parts connected to one another is understood here and in the following in particular to mean that the parts connected to one another are prevented from sliding off one another due to a frictional force acting between them. If there is no "connection force" that causes this frictional force (this means the force that presses the parts against one another, for example a screw force or the force of weight itself), the non-positive connection cannot be maintained and can therefore be released.

The silencer is preferably completely manually dismantled and can be assembled by a user without any risk.

In a preferred embodiment, the clamping device is designed as a collet. The collet has here, for example, an externally conical, radially slotted, sleeve with a central bore as a receptacle or Through hole for the gun barrel. The sleeve or the bore are here adapted to the respective barrel diameter of the gun barrel. In this case, the collet is clamped onto the gun barrel, for example by means of a key or lever. This ensures a particularly stable and reliable attachment of the silencer. In particular, a cost-reduced and always centering clamping of the gun barrel is thus realized.

In a suitable embodiment, the clamping device is arranged on an end face of the muffler housing. In other words, the clamping device is arranged on a side of the muffler housing opposite the outlet opening. In this case, the end face is designed, for example, as a removable housing cover.

In one possible embodiment, the silencer is designed, for example, as an integral silencer, with the silencer housing not only being placed on the barrel muzzle, but rather extending essentially completely over the gun barrel in its longitudinal direction and enclosing it at least in sections like a jacket. This optimizes a damping performance of the muffler. By arranging the clamping device or collet at the front, a center of gravity of the silencer is shifted to the rear, ie in the direction of the firearm and away from the muzzle of the gun barrel. Furthermore, the silencer thus has a particularly space-compact structure in front of the muzzle barrel, as a result of which the handling and balance of the firearm equipped with it is significantly improved.

In an expedient embodiment, the end face of the muffler housing is provided with an internal thread into which an external thread of the clamping device is screwed or can be screwed. In other words, the clamping device or the collets are screwed into the end face or the housing cover. As a result, a simple and non-destructively detachable attachment of the clamping device to the muffler housing is realized. As a result, on the one hand, easy assembly and disassembly of the silencer, for example maintenance purposes. On the other hand, it is thus possible to exchange or change the clamping device or the collet, so that the silencer can be adapted particularly variably and flexibly to a respective weapon barrel by changing the clamping device.

In an advantageous development, the clamping device has at least one seal on an inner circumference surrounding or enclosing the gun barrel. In the assembled state, the clamping device—and thus the silencer—is sealed by means of the seal relative to the outer circumference of the gun barrel, in particular in a gas-tight manner. On the one hand, the forces of the gas pressure of the combustion gases and, on the other hand, the clamping or clamping effect of the clamping device or collet are absorbed by the seal. The seal also increases the frictional resistance and thus the non-positive holding force on the gun barrel.

Furthermore, the at least one seal allows the jacket pipe not to be permanently installed inside the muffler housing, as a result of which a larger expansion chamber can be implemented. This further improves the muffling performance of the muffler.

An additional or further aspect of the invention provides a centering sleeve for centering the weapon barrel, which is arranged on an end face of the jacket tube facing the muzzle brake. The silencer is thus centered on the bore axis of the gun barrel via the centering sleeve. The gun barrel is thus held at two points by the centering sleeve and the clamping device. As a result, a reliable and secure mounting and alignment of the silencer on a non-threaded gun barrel is realized.

When used on a gun barrel provided with a muzzle thread, it is possible, for example, to exchange or change the centering sleeve with a threaded insert or a threaded sleeve in order to screw the silencer onto the gun barrel or onto the muzzle thread. With such a screw fastening, it is conceivable, for example, that on the end face or the housing cover of the silencer housing, a plastic insert is introduced, which prevents the gun barrel from being scratched when it is put on.

In a conceivable embodiment, the muzzle brake is screwed to the jacket tube. This results in a reliable fastening and holding of the steering column jacket in the muffler housing. For example, the muzzle brake is screwed to the jacket tube on the outside, for which purpose the jacket tube has an internal thread and the muzzle brake has an external thread.

In an expedient embodiment, the device has a (baffle wall) chamber with a number of baffle walls and/or a (gas rotation) chamber with a gas rotation insert. The device preferably has both a baffle chamber and a gas rotation chamber, which are connected downstream of one another. This enables a reliable reduction of noise emissions and the muzzle flash.

The baffle walls are designed here, for example, as reflection surfaces for the combustion gases. Here, the propellant gases of the projectile escaping from the muzzle are slowed down and cooled, which leads to a reduction in the muzzle blast and muzzle flash. The baffle walls are each designed, for example, as the envelope of a cone and have, for example, an opening angle of approximately 45°.

The rotary gas insert has a significant influence on the damping performance of the muffler. Due to the (gas) rotation insert, the gases are cooled very quickly and the muzzle blast is swirled. In this case, the rotary insert preferably has a shape or geometry that achieves a particularly high damping performance in as compact a space as possible.

In a particularly preferred embodiment, the gas rotation insert is produced as an exchangeable 3D printed part. This means that the rotary gas insert is manufactured using a three-dimensional printing process, a particularly effective and suitable shape and geometry in terms of damping performance is made possible. This makes it possible to produce the silencer in much shorter designs, which brings a significant advantage for the handling of a firearm equipped with it.

Due to the exchangeability or interchangeability of the rotary gas insert, it is also possible to adapt the silencer flexibly to a respective caliber of the firearm. For example, when the caliber is changed, only the rotary gas insert needs to be replaced.

In a suitable further development, an intermediate space is formed as an expansion chamber between the muffler housing and the casing tube, with the muffler housing having at least one ventilation hole for the intermediate space. The ventilation hole can also be part of the device, for example. Cold air can escape from the expansion chamber through the ventilation hole, so that the hot (combustion/drive) gases can spread out faster and be cooled down. This further improves the muffling performance of the muffler.

Furthermore, this has the additional effect that the silencer does not heat up as quickly. This reduces visible flickering in an optical sight (scope) due to rising heat. In particular, such a flickering occurs only after several shots have been fired in quick succession.

Furthermore, it is possible through the ventilation hole that moisture can escape from the jacket pipe. The term "moisture" is to be understood here and in the following in particular as the presence of water, in particular in the form of water vapor from atmospheric moisture in the air enclosed in the casing tube. This means that there can be unbound water content inside the casing tube, which can react chemically with powder residues, for example, and can lead to damage or corrosion. The ventilation hole ensures that moisture is removed can escape through the mandrel, improving the life of the mandrel and thus the muffler.

The invention is explained in more detail below with reference to a drawing. In it, the only figure shows a silencer mounted on a gun barrel.

The figure shows a perspective sectional view of a silencer 2, which is mounted on the muzzle side on a gun barrel 4 of a firearm, not shown in detail. For example, the firearm is a hunting rifle. In this exemplary embodiment, the gun barrel 4 has no muzzle thread. In other words, the gun barrel 4 is therefore designed without a thread.

The silencer 2 is designed in particular as an integral silencer and has a cylindrical or tubular silencer housing 6 as an outer jacket tube, which completely encloses the weapon barrel 4 in sections. An (inner) jacket tube 8 is accommodated in the silencer housing 6 and coaxially encloses the weapon barrel 4 . The jacket tube 8 is held centered in the silencer housing 6 on the one hand by means of a muzzle brake 10 . On the other hand, the casing tube 8 sits in a receptacle (not designated in any more detail) of an annular housing cover 12 which closes the muffler housing 6 at one end.

The muzzle brake 10 engages at least in sections in the jacket tube 8, with a centering sleeve 14 being arranged in the engaging region of the muzzle brake 10, by means of which the gun barrel 4 is aligned on the muzzle side, centered in the jacket tube 8 or the silencer housing 6. The muzzle brake 10 is provided with an external thread in the engaging area, which is screwed into a corresponding internal thread of the jacket tube 8 .

The housing cover 12 has a threaded hole on the outside of the housing, into which a clamping device 16 designed as a collet is screwed. For this purpose, the clamping device 16 has an external thread Mounting portion, which is screwed into the internal thread of the threaded bore. The clamping device 16 fixes the silencer 2 in the assembled state in a positive and/or non-positive manner on the gun barrel 4.

The clamping device 16 has four axially distributed seals 18 which are arranged as radial ring seals on a weapon barrel 4 surrounding or enclosing the clamping device 16 . In the assembled state, the clamping device 16—and thus the silencer 2—is sealed by means of the seals 18 relative to the outer circumference of the weapon barrel 4, in particular in a gas-tight manner. The forces of the gas pressure of the combustion gases on the one hand and the clamping or clamping effect of the clamping device 16 or collet chuck on the other hand are absorbed by the seals 18 . The seals 18 also increase the frictional resistance and thus the non-positive holding force on the gun barrel 4.

“Axial” or an “axial direction” is understood here and in the following in particular as a direction parallel (coaxial) to the gun barrel 4 , that is to say perpendicular to the end faces of the silencer 2 . Correspondingly, here and in the following, “radial” or a “radial direction” is understood to mean, in particular, a direction oriented perpendicular (transverse) to the longitudinal axis of the gun barrel 4 along a radius of the gun barrel 4 or the silencer 2 . Here and in the following, "tangential" or a "tangential direction" means in particular a direction along the circumference of the silencer 2 or the gun barrel 4 (circumferential direction, azimuthal direction), i.e. a direction perpendicular to the axial direction and to the radial direction.

The figure also shows a projectile 20 fired from the gun barrel 4, which is shown in the area of a device 22 for deflecting and/or cooling a (propellant/combustion) gas produced when a shot is fired. The device 22 here has a baffle wall chamber 24 and a gas rotation chamber 26, which adjoin the muzzle brake 10 in axial succession.

The baffle wall chamber 24 has, for example, two baffle walls 28 arranged one behind the other. The impact walls 28 are each designed, for example, as a cone envelope of a cone and have, for example, an opening angle of approximately 45°.

An approximately hollow-cylindrical gas rotation insert 30 is accommodated in the gas rotation chamber 26 .

The gas rotation insert 30 preferably has a shape or geometry that achieves a particularly high damping performance in as compact a space as possible. In particular, the gas rotation insert 30 is manufactured as an interchangeable 3D printed part.

Between the muffler housing 6 and the jacket tube 8 is an unspecified intermediate space (annular space) is formed as an expansion chamber. The muffler housing 6 has at least one ventilation hole 32 which penetrates the muffler housing 6 approximately radially and thus couples the expansion chamber or the intermediate space with the environment. Cold air can escape from the expansion chamber through the ventilation hole 32, so that the hot (combustion/motive) gases can spread and be cooled more quickly.

The silencer 2 can preferably be completely dismantled manually and assembled by a user without any risk.

The invention is not limited to the exemplary embodiments described above. On the contrary, other variants of the invention can also be derived from this by a person skilled in the art without departing from the subject matter of the invention. In particular, all of the individual features described in connection with the exemplary embodiments can also be combined with one another in other ways without departing from the subject matter of the invention.
