Definitions

  • the invention relates to a silencer for firearms, in particular handguns or fist guns, which has an outer tube in which a damping core is arranged, which has a projectile channel and impact walls, whereby annular chamber compartments are formed which are separated from one another in a gas-tight manner, wherein the outer tube and/or the damping core is made of aluminum.
  • Silencers for handguns or pistols are well known. Silencers have an outer tube that forms a cylindrical space inside, in which a damping core is arranged.
  • the damping core can be designed in one or more parts. It has a bullet channel that usually runs along its longitudinal center line.
  • the damping core has impact walls, which form ring chamber compartments that are separated from each other in a gas-tight manner. The ring chamber compartments slow down and cool the propellant gases of the projectile that exit the muzzle, which reduces the sound emission when a shot is fired and thus reduces the muzzle blast and muzzle flash.
  • Silencers are originally made of steel because they absorb heat very well. Their main disadvantage is their relatively high weight. For this reason, silencers made of aluminum are increasingly being used, especially in hunting. However, silencers made of aluminum have only a low thermal resistance. This is particularly true for rapid bursts of fire from automatic or semi-automatic weapons, for example with several shots fired in quick succession or continuous fire. This can lead to the silencer failing.
  • silencers made of steel are almost exclusively used by the military, police or other security authorities, which leads to earlier fatigue during long-term use.
  • the invention is based on the object of creating a silencer which, on the one hand, is lightweight and, on the other hand, can withstand the high thermal loads when shots are fired in quick succession or when firing continuously. According to the invention, this object is achieved with the features of claim 1.
  • the invention creates a silencer that is lightweight and at the same time can withstand the high thermal loads that occur when shots are fired in quick succession or when fired continuously. This is due to the steel tube that surrounds the bullet channel, which easily withstands the high temperatures that occur. At the same time, the weight of the silencer according to the invention is only slightly higher than that of the silencers known from the prior art, which are made entirely of aluminum.
  • the inner tube prefferably be provided with an outer ring at the end facing the rear.
  • the outer ring creates a positive connection between the inner tube and the damping core. It prevents the inner tube from being driven out of the damping core by the bullet and the air pressure.
  • the inner tube is provided with holes.
  • the holes allow the propellant gases emerging from the muzzle to escape into the annular chamber compartments. This slows down and cools the propellant gases.
  • front and back or front and back refer to the direction of fire, with the front pointing in the direction of fire and the back pointing against the direction of fire.
  • the silencer chosen as an embodiment is intended in particular for use on handguns or pistols. It consists of an outer tube 1 in which a damping core 2 is arranged.
  • the damping core 2 is one-piece; in a modification of the embodiment, the damping core can be designed in several parts. It has a bullet channel 3 that runs along its longitudinal center line.
  • the outer tube 1 and the damping core 2 are made of aluminum.
  • the term aluminum in the sense of the present invention also includes aluminum alloys, for example aluminum-zinc alloys.
  • the damping core 2 has impact walls 4, whereby, when inserted into the outer tube 1, annular chamber compartments 5 are formed which are separated from one another in a gas-tight manner.
  • the damping core 2 has a plurality of bores 6 between the impact walls 4 and in an area facing the rear.
  • an inner tube 12 is inserted into the bullet 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 impact wall 4 facing the rear. At its end facing the rear, the inner tube 12 in the exemplary embodiment is provided with an outer ring 13.
  • the inner tube 12 is provided with holes 14 which are aligned congruently with the holes 6.
  • the inner tube 12 is first made of steel.
  • the inner tube 12 is then placed in a casting mold and cast with aluminum using the aluminum die-casting process.
  • the aluminum is pressed into a preheated steel mold in a liquid or pasty state under high pressure.
  • the inner tube 12 is a non-detachable part of the damping core 2.
  • Casting the damping core 2 is significantly more cost-effective than the machining process previously used.
  • the holes 6 and 14 are then drilled radially into the assembly consisting of the damping core 2 and the cast-in inner tube 12.
  • the damping core 2 is then inserted into the outer tube 1 and screwed to it, with sealing means being provided on both flanges 9 and 10 so that a gas-tight connection is created between the outer tube 1 and the damping core 2.
  • 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 accommodated 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 from the front of the silencer.
  • the propellant gases of the projectile exiting from the muzzle of the weapon's barrel enter through holes 6 and 14, which serve for ventilation and sound refraction. Through holes 6 and 14, the propellant gases can enter the annular chamber compartments 5, whereby the propellant gases are slowed down and cooled. This reduces the noise emission and the muzzle blast.
  • the silencer according to the invention is able to withstand the high thermal loads during bursts of fire or continuous fire from automatic or semi-automatic handguns that are fired in quick succession. This is ensured by the inner tube 12 made of steel and capable of withstanding 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. By producing the damping core 2 using the aluminum die-casting process, the manufacturing costs are also reduced.
