A silencer according to claims 1-5, which differs in that the baffles-diaphragms and the output flange of the silencer - its outer surfaces are covered with a sound-absorbing barrier, equipped with diffusers at the entrance, and with a material at the exit, for example silicone rubber. d) nozzles, while the length of the diffuser is not less than 7. The muffler according to claims 1-6, which differs in that 5 diameter of the passage channel and no more than half of the nozzle of the outlet flange is made variable with the possibility of the size of the expansion chamber along the axis, in the node by pouring fixing on the muffler by connecting the input flange with the barrel of the weapon and the compression flange with a threaded connection to the elastic element that interacts with the muffler. the barrel of the weapon, and the nozzle of the output flange is made of steel. The invention relates to firearms and the barrel of a firearm.

At the same time, the overburner is designed to muffle the sound of a shot from the diaphragm, having a disk-like shape, as a small-arms weapon, including an automatic one, in the form of three-dimensional bodies with a complex profile.

During the training, training and other new feature of the partitions, made for firing, as well as during the execution of combat by the patent, is that the axial opening, "operations that involve the use of fire- intended for the passage of a bullet, has gunshot wounds. (relative to the axis) side surfaces that deflect the gas flow, which is directed behind the bullet during firing, from the gun, which is the closest analogue (prototype) of the longitudinal axis of the silencer.

According to this patent, the proposed technical solution is changed.

This muffler houses-diaphragms are fixed inside the cavity- includes a hollow cylindrical body with a hollow cylindrical body with the help of inlet and outlet flanges, as well as over-rotary bushings, made in the form of thin-walled dka-diaphragms, installed inside the body. cylinders (options 1, 2) or in the form of cut-off flanges and partitions have holes for bullet passage coaxial with the barrel of solid-walled cones with large and small diameters of weapons.

The inlet flange (options 3, 4), installed with a smaller diameter, is equipped with a connection unit of the muffler with the opposite gas flow.

At the same time, the diameter of the

cylindrical bushings and a larger diameter of the truncated cone. In addition, in the passage channels of the diffusers and the sonus, the diameter of the diaphragms (at least in one of them) is the same as the diameter of the profile rods-diaphragms.

In addition, in the partitions there are also curtain loops. In addition, diaphragm partitions (at least additional side openings for organization, as in the above first one along the course of the bullet) are made together with the diffuser and the considered patents, directed in different directions by a nozzle made of refractory material. gas flows inside the muffler.

In addition, the outer surfaces of the muffler are coated with a sound-absorbing material, for example, silicone, to increase the effectiveness of the sound of the shot. can be placed inside the muffler, in particular, in the In addition, the nozzle of the outlet flange of the muffler enters the expansion chamber, the low-melt re- is made variable and is fixed on the muffler by the impurity, which evaporates, for example, with the help of a grease ring-washer with a threaded connection to the PI mass. silencer

The disadvantage of a muffler for the sound of a small-arms shot. Such essential distinguishing features of a muffler that pro- weapons manufactured according to the prototype is that it is assumed that the baffles-diaphragm and (or) relatively high cost of production, the outlet flange of the muffler is equipped on the entrance is filled with a complex profile shape of disc-shaped diffusers, and at the exit - nozzles with the length of the partitions-diaphragms, and the low efficiency of the diffuser is not less than the diameter of the passage channel and sound deadening, other things being equal, is no more than half the size of the expansion chamber dimensional and mass characteristics of the glumera along the axis, at the junction of the inlet flange with the muzzle, due to the relatively large filling - the barrel of the weapon has an elastic element mounted on it, the volume of which is limited by a hollow cylinder - interacts with the barrel of the weapon, and, in addition, the nozzle with the muffler body turned out.

The general essentials of the bottom flange are made of elastic material, features of the well-known silencer of the sound of the shot, the tape has elastic-hysteresis properties, there are sufficient weapons, what is offered, is the presence in them in all cases, which is spread by the 6th hollow case-sleeves with input and output of legal protection of the proposed invention. bottom flanges installed inside the body- Other distinguishing features characterize the silencer of the sleeve of partitions-diaphragms with coaxial with the shot- shot in some cases of its execution. weapon scrap with holes for the passage of a bullet, due to the presence of diffusers (at the entrance) and nozzles (on the other hand, the front flange is equipped with a connector assembly) near the diaphragm partitions (in all cases or due to the connection of the silencer with the weapon. , one of them), on the one hand, creates a favorable

The basis of the muffler for the sound of a rifle shot is the conditions for the occurrence of the vortex movement of gases in the weapon, which is proposed, the task of the expansion chambers of the muffler is set, on the other hand - to ensure, at a given volume of the muffler, and worsens the conditions of gas leakage through the passage channel given its dimensional and mass characteristics, diaphragm.

This reduces the speed and lengthens the time of the greatest muting effect, while at the same time gas exits from one expansion chamber in another reduction of labor and material costs for noise, which leads to a decrease in the level of its sound production. pressure, which is generated by the flow of gas flowing from

The task is solved by the fact that the outlet nozzle of the muffler. the muffler, which contains a hollow body. The presence of diffusers and a sleeve with inlet and outlet flanges in the passage channels, installed nozzles of profiled annular grooves increases the resistance inside the body-sleeve of the partition-diaphragm with the gas flow passing through the channel, and is equidistant from the barrel of the weapon through holes for passage helps to increase the time of leakage of the products of the bullet adjustment, and the inlet flange of the silencer of the powder charge. equipped with a removable assembly for connecting it with the presence of an elastic element in the silencer, which, according to the invention, interacts with the barrel of the weapon and the silencer body. and at the outlet - nozzles, when the muffler is turned on, especially in automatic mode, the length of the diffuser is not less than the diameter of the firing passage. of the channel and no more than half the size of the expansion. The presence of a nozzle on the output flange of the silencer chamber along the axis, and in the connection node of the inlet, made of a material that has an elastic-elastic flange of the silencer, with the barrel of the weapon, resistive properties are mounted, for example, from rubber, through an elastic element that interacts with the barrel of the weapon, and, large losses in it, leads to a decrease in the re elastic muffler material.

The execution of an elastic element in the form of a coil, which has elastic-hysteresis properties, a disk spring fixed in an annular bellows, silicone rubber. of the inlet flange of the muffler, provides the possibility of

In addition, the elastic element of the muffler, the performance of the compact design of the connector assembly is in the form of a corrugated plate spring, the different connection of the muffler with the barrel of the shooter, installed in the annular groove of the flange from external weapons of various designs, for example, for the side that interacts with the protrusion that the silencer of the Kalashnikov model goes on the barrel of the weapon.

AKM is best suited to the option, executed

In addition, the corrugated plate spring according to the scheme shown in fig. 2, and for the model, it is attached to the inlet flange in the ring groove of the AK-7AM - in fig. 3. inside the muffler and interacts with the end section. Performance of diaphragm partitions with a diffuser of the barrel of the weapon. and a nozzle made of refractory material contributes to the

increasing the stability of the internal elements of the silencer during automatic firing, because in this case they have diffusers 20 and nozzles 21, and also heat up more (to a red color) and bare pneumatic resistance in the powder channels. even the inlet edges of the diffusers are melted. In fig. 2 and C show options for the design. Covering the external surfaces of the muffler with a sound-absorbing material improves the sound-absorbing material of the threaded connection of the muffler. The design of the outlet nozzle, where the elastic element is made in the form of a muffler in the form of a replaceable rubber gasket of a roller spring 5 and installed from the outside (Fig. 2), increases the life of the muffler, because it allows you to change it inside (Fig. 3) the inlet flanges. At the same time, the nozzle is activated. in fig. C shows a supporting thrust flange 24 mounted in the inlet flange. 4 ka of the sound of a shot of a small-arms weapon are depicted in the shown construction diagram of the implementation of single-line drawings, which show: a measuring silencer.

Getting into the corresponding chamber, the jet of the nozzle 2, which is made together with the docking unit, expands, therefore part of the gas flow of a rifled, for example, muffler with a gun barrel 4. spits into the diffuser, and part - past the diffuser, which A spring is placed between the muffler and the barrel of the weapon. This is where element 5 takes place, which is made, for example, in the form of a change in the momentum of the kinetic energy of a supersonic split elastic washer, which prevents backlash and gas jets. According to the extent of gas leakage, the pressure in each self-unscrewing of the muffler in the process of automa- chamber drops, and the gas, alternately passing through each tic firing. In the inner cavity of the housing-chamber, it loses energy in each of them and, thus, the sleeves 1 are located three (pos. 6, 7 and 8) profile and nom, the total time of its leakage from the outlet is prolonged (pos. ) annular partitions-diaphragms, traveling nozzle 23. The extension of the leakage time is fixed with the help of, for example, six expanded volume of powder gases adequately reduced- porous annular bushings (items 11, 12, 13, 14, 151 nu sound of pressure on the section of the outlet nozzle
