Definitions

  • the invention is intended to create a new kind of gun silencer, which does not have a detrimental effect on the accuracy of the aim of the gun, but which not only silences the sound but also effectively attenuates the recoil of the gun.
  • the characteris- tic features of the present invention appear in the accompanying Claims.
  • the combustion gases are directed to turn, in a controlled manner, rapidly in the opposite direction to the direction of travel of the bullet, so that the force then created reduces the recoil of the gun. Though the change in direction of movement is rapid, it takes place in stages, to reduce the impulse loading the construction.
  • the real effect is created by ensuring a continuous flow for the combustion gases, inside the silencer. At the same time, the sound is effectively reduced.
  • FIG 1 shows silencer 10 according to the invention attached to a rifle 11.
  • telescopic sights 12 are used with the silencer.
  • the silencer 10 which is thicker than the barrel 13, does not, however, interfere with aiming, especially when higher mounting bases are used for the sights.
  • the silencer according to the invention can be attached to nearly all kinds of guns, though the attenuation achieved with it is particularly significant in the case of high-pressure guns, such as rifles.
  • high-pressure guns the pressure of the combustion gases discharging from the mouth of the barrel is about 600 bar. The pressure is naturally dependent on the charge in the cartridge. The range of such guns is great, so that the silencer should affect the flight of the bullet as little as possible, preferably not at all.
  • Figure 2a shows the gun silencer assembled and attached to the barrel 13, when bullet 14 comes out of barrel 13 after firing.
  • FIG. 2b shows the same situation a moment later. Barrel 13 is only shown in part.
  • Silencer 10 includes a cylindrical jacket
  • jacket 17 is mainly formed by a special discharge pipe 15 and an end piece 19.
  • the expansion chamber 16 is also delimited by the end formed in end piece 19 and seal component 23.
  • the operation of the discharge pipe and at the same time of the whole silencer is thus based on a rapid change, through 180 degrees, in the direction of flow of the combustion gases discharging from the mouth of the barrel, when a force in the opposite direction to the recoil, i.e. a recoil reducing force, in created.
  • the recoil is also cancelled by the impact of the combustion gases against the frontal surfaces.
  • the large expansion chamber a sufficiently large pressure difference is maintained, during the shot, between the mouth of the barrel and the rear end of the silencer.
  • the inner surface of the discharge pipe is smooth, with no protrusions.
  • One typical application is a .308 caliber game-target event competition gun, which uses a telescopic sight with high mounting bases.
  • the properties of the silencer are emphasized in connection with such a gun.
  • the attenuation of the recoil improves the accuracy of aim and reduces the strain on the competitor, especially when firing series.
  • the attenuation of the sound is especially advantageous to spectators.
  • the total weight of the gun remains reasonable and, despite dismantling and cleaning, the accuracy of aim of the gun is retained.

Abstract

L'invention concerne un silencieux pour fusil se composant d'un manchon du canon essentiellement cylindrique (17) qui, avec le canon (13) du fusil (11) délimite une chambre d'expansion (16) qui reçoit les gaz de combustion provenant de l'embouchure du canon prêts à être déchargés de manière à amortir le bruit du tir. Le silencieux (10) comprend en outre un cône déflecteur (21) et une pièce d'extrémité réfléchissant les gaz de combustion. La chambre d'expansion (16) se trouve derrière l'embouchure du canon (13). Le silencieux (10) comprend aussi un cône guide (20) entourant l'embouchure du canon (13) et se dilatant vers l'avant et de manière coaxiale autour du cône déflecteur (21). Des trous (22) sont ménagés dans le cône guide servant à évacuer les gaz de combustion.
