Definitions
- the utility model relates to silencers (sound moderators) for pneumatic weapons.
- silencers for pneumatic weapons use expansion chambers (with and without baffles) - see, for example, the block of UK patents: GB2104197A, GB2106619A, GB2156053A, GB2193562A. These design features are also used in silencers for firearms.
- the proposed utility model is closest to the designs, the reduction of the noise level in which is achieved by quickly closing the hole behind the flying bullet and isolating the expanding portions of gases in separate, relatively sealed (expansion) chambers. Bleeding occurs through leaky connections or special holes in the muffler body (see, for example: https://survival.com.ua/variantyi-konstruktsii-glushiteley-nasadok-glusheniya-zvuka-vyistrela-strelkovogo-oruzhiya/).
- the simplest sound moderator (silencer) was chosen, which is an expansion chamber into which an element of sponge rubber (elastic insert) is inserted, cut along the inner diameter of the expansion chamber, with a hole in the center
- the utility model is aimed at eliminating the above technical problem inherent in the prototype.
- EFFECT design of the muffler (sound moderator) excludes blowing out of the elastic element from the expansion chamber.
- a silencer for pneumatic weapons consisting of an expansion chamber and installed inside an elastic element, in which, according to the proposal, the elastic element is installed partially on a sleeve that goes inside the expansion chamber, rigidly fixed in the outlet end of the expansion chamber coaxially with the weapon barrel.
- FIG. 1 shows a longitudinal section of a silencer corresponding to the prototype device.
- Options A and option B differ in the shape of the elastic element.
- FIG. 2 shows a longitudinal section of the proposed muffler.
- Options A and option B also differ in the shape of the elastic element.
- the silencer consists of an expansion chamber (body) 1, a cover 2 (the cover is adapted for mounting on a pneumatic weapon, in the demonstrated version, the cover can be equipped with an internal thread for screwing onto the weapon barrel), a sleeve (installation sleeve) 3 and an elastic element 4 Mounting sleeve 3 is rigidly fixed in body 1. Holes in cover 2 and sleeve 3 are on the same axis and serve for the passage of a bullet.
- An elastic element 4 is installed on the mounting sleeve 3. Preferably, the outer diameter of the elastic element 4 is less than the inner diameter of the housing 1.
- the elastic element 4 is made of an elastic elastic material (porous, sponge rubber). Installation of the elastic element 4 on the mounting sleeve can be done manually without special equipment When fired, the bullet passes through the hole in the cover 2, the mounting sleeve
- the elastic element 4 is smaller than in case 1, due to this, the elastic element 4 closes, collapses.
- the collapse of the elastic element 4 leads to partial cutting off of the air flow following the bullet.
- a further decrease in the inner diameter of the elastic element 4 a gradual increase in pressure occurs inside the housing 1, which leads to a complete locking of air in the internal volume of the housing 1.
- the protruding edge of the mounting sleeve 3 and the physical and mechanical properties of the material of the elastic element 4 prevent the elastic element 4 from blowing into the outlet of the sleeve 3. Further, the air from the internal cavity of the housing 1 exits through leaky connections, after which the elastic element 4, due to its elasticity, returns to its original state.
- the preferred material was the 1-20 press plate TU 38 105867-90 or the rubber technical plate (sponge) R-29 according to TU 38105121-91.
- the specified grades of materials of the elastic element 4 are given solely to confirm the implementation of the utility model, but not for the purposes of determining the scope of rights, since there are a large number of materials with similar physical and mechanical properties that can be used for manufacturing elastic element 4 with the achievement of the specified technical result with varying degrees of efficiency.
