Definitions
- the invention relates to a silencer for firearms, in particular handguns or handguns, which has an outer tube in which a damping core is arranged, which has a projectile passage and impact walls, whereby annular chamber compartments are formed which are separated from one another in a gas-tight manner, the outer tube and/or the damping core consists of aluminum.
- Silencers for handguns or handguns are known per se.
- the mufflers have an outer tube which forms a cylindrical space inside, in which a muffling core is arranged.
- the damping core can be designed in one piece or in several pieces. It has a bullet channel that usually runs along its longitudinal centerline.
- the damping core has baffle walls, as a result of which annular chamber compartments are formed which are separated from one another in a gas-tight manner. The annular chamber compartments slow down and cool the propellant gases of the projectile escaping from the muzzle, which reduces the sound emission when a shot is fired and thus leads to a reduction in the muzzle blast and muzzle flash.
- Mufflers are originally made of steel because they have very good heat absorption. A particular disadvantage of them is their relatively high weight. For this reason, silencers made of aluminum are increasingly being used, especially in hunting applications. However, silencers made of aluminum are only slightly thermally resilient. This applies in particular to quick salvos from automatic or semi-automatic weapons, for example with several shots fired in quick succession or continuous fire. This can lead to the failure of the silencers.
- the invention is based on the object of creating a silencer which, on the one hand, has a low weight and, on the other hand, withstands the high thermal loads resulting from shots being fired in quick succession or continuous fire. According to the invention, this object is achieved with the features of claim 1.
- a silencer is created that is lightweight and at the same time withstands the high thermal stresses of shots fired in quick succession or sustained fire. This is caused by the steel tube surrounding the bullet channel, which easily withstands the high temperatures that occur.
- the weight of the silencer according to the invention is only slightly higher than that of the silencers known from the prior art, which consist entirely of aluminum.
- the inner tube is advantageously provided with an outer rim at its end facing the rear side.
- the outer ring leads to a positive connection of the inner tube with the damping core. It prevents the inner tube from being forced out of the cushioning core by the bullet and the air pressure.
- the inner tube is provided with bores.
- the bores allow the propellant gases escaping from the muzzle to escape into the annular chamber compartments. This slows down and cools the propellant gases.
- FIG. 1 shows the longitudinal section through a silencer according to the present invention
- FIG. 2 shows the longitudinal section through a damping core
- Figure 3 shows the longitudinal section through an inner tube on an enlarged scale
- FIG. 4 shows the longitudinal section through the damping core with the inner tube.
- front and back or front and back refer to the weft direction, with the front pointing in the weft direction and the back pointing against the weft direction.
- the silencer selected as an exemplary embodiment is intended in particular for use on handguns or handguns. It consists of an outer tube 1 in which a damping core 2 is arranged.
- the damping core 2 is in one piece in the embodiment; as a modification of the exemplary embodiment, the damping core can be designed in several parts. It has a bullet channel 3 running along its longitudinal centerline.
- Outer tube 1 and damping core 2 are made of aluminum in the exemplary embodiment.
- the term aluminum for the purposes of the present invention also includes aluminum alloys, for example aluminum-zinc alloys.
- the damping core 2 has impact walls 4, as a result of which annular chamber compartments 5 are formed when inserted into the outer tube 1, which are separated from one another in a gas-tight manner.
- the damping core 2 has a multiplicity of bores 6 between the baffle walls 4 and in an area facing the rear.
- an internal thread 7 is arranged in the damping core 2 immediately adjacent to the area provided with the bores 6 and is used for screwing to the weapon.
- the internal thread 7 is followed by a hollow-cylindrical section 8 which, when mounted on the weapon, partially accommodates the barrel of the weapon.
- the back and the front of the damping core 2 are formed by flanges 9 and 10, the outer diameter of which corresponds to the inner diameter of the outer tube 1.
- the rear flange 9 has an external thread 11 which corresponds to an internal thread (not shown) in the outer pipe 1 .
- an inner tube 12 is inserted into the projectile channel 3 .
- the inner tube 12 is made of steel. In the exemplary embodiment, it extends only partially through the damping core 2, namely from the front of the silencer to the last baffle 4 facing the rear.
- the inner tube 12 is provided with bores 14 which are aligned with the bores 6 congruent.
- the inner pipe 12 is first made of steel.
- the inner tube 12 is then placed in a mold and cast around with aluminum using the aluminum die-casting process.
- the aluminum is pressed into a preheated steel mold under high pressure in a liquid or doughy state.
- the inner tube 12 is a non-detachable part of the damping core 2.
- the casting of the damping core 2 is significantly more cost-saving than the machining turning that has been used hitherto.
- the bores 6 and 14 are then drilled radially into the assembly made up of the damping core 2 and the cast-in inner tube 12 .
- the damping core 2 is inserted into the outer tube 1 and screwed to it, sealing means being provided on both flanges 9 and 10 so that a gas-tight connection between the outer tube 1 and the damping core 2 is created.
- the silencer When using the silencer according to the invention, it is screwed onto the barrel of the weapon with the internal thread 7 . The barrel is then partially taken up by the section 8 . When a projectile is fired, it exits the barrel and enters the bullet channel 3 or the inner tube 12 and exits at the front of the silencer.
- the propellant gases of the projectile emerging from the muzzle of the barrel of the weapon pass through the bores 6 and 14, which are used for ventilation and sound refraction.
- the propellant gases can enter the annular chamber compartments 5 through the bores 6 and 14, as a result of which the propellant gases are slowed down and cooled. This reduces the noise emission and reduces the muzzle blast.
- the silencer according to the invention is able to withstand the high thermal loads in the case of short-term successive bursts of fire or sustained fire from automatic or semi-automatic handguns or handguns. This is ensured by the inner tube 12, which is made of steel and can withstand high thermal loads. At the same time, the silencer is significantly lighter than the silencers known from the prior art and suitable for continuous fire, which are made entirely of steel. The production costs are also reduced as a result of the production of the damping core 2 using the aluminum die-casting process.
