Description

The utility model relates to weapons technology, namely to a chamber for a product structurally similar to firearms (KSOOI), and can be used for sports and recreational shooting of various projectiles using blank charges.

Known designs of chambers for signal weapons in the form of a blind sleeve, as, for example, for the revolver R-2 of the Izhmash company, or in the form of a truncated cone, as in the Luger R-08 pistol (https://www.svl.ru /article/195081/new_signalnyiy-revolver---tehnicheskie-harakteristiki-signalnyie-pistoletyi-harakteristiki).

The disadvantage of such designs is the ability to use only the "chewed" capsules, which limits the ability of the weapon's automation and the effectiveness of shooting due to the fact that the capsules do not have enough energy to ensure the movement of parts of the weapon.

According to Article 13 of the Law on Weapons of December 13, 1996 No. 150-FZ, flare pistols and revolvers of a caliber of not more than 6 mm and cartridges for them, which, according to the conclusion of the federal executive body responsible for the development and implementation of state policy and legal regulation in the field of internal affairs, cannot be used as firearms and gas weapons, are purchased without a license and are not registered.

The closest proposed technical solution is a chamber for sports firearms, for example, revolver-type weapons, containing a cylindrical channel made in the barrel body for accommodating a cartridge with a conical part, which, at the truncation point, is associated with the barrel channel through a cylindrical connecting channel (FR 2852095 A1, publ. 09/10/2004).

The known design makes it possible to provide a cylindrical centering of the projectile when it is directed into the barrel, which increases the accuracy of shooting, but cannot be used for KSOOI due to the inability to control the energy of the shot and, accordingly, the use of different types of projectile elements.

The utility model is aimed at solving the problem of increasing the efficiency of controlling the energy of a shot by projectiles while expanding the arsenal of technical means for KSOOI.

The problem is solved by the fact that the chamber for a product structurally similar to a firearm contains a cavity for accommodating a missile element and a cavity for accommodating a low-pulse source of powder gases, which are interconnected by a gas outlet, the entrance of which into the cavity for accommodating a missile element is located eccentrically to the axis of this cavity, and the cross-sectional area of the gas outlet is less than the cross-sectional area of the projectile element.

In this case, the cavity for accommodating the projectile element may have a shape corresponding to the shape of the projectile element.

In this case, the gas outlet can be made in the form of channels, the entrances of which into the cavity for placing the projectile element are located along its periphery.

The execution of the chamber in the form of a cavity for accommodating a projectile element, communicated by a gas outlet with a cavity for accommodating a low-pulse source of powder gases, allows you to control the energy of powder gases, based on the characteristics of the source of powder gases, since the design of the chamber is adjusted to a specific source of powder gases.

The location of the gas outlet inlet to the cavity for the placement of the projectile element is eccentric to the axis of this cavity, as well as the execution of the gas outlet in the form of channels, the entrances of which to the cavity for the placement of the projectile element are located along its periphery, which makes it possible to prevent the excess of the energy of powder gases due to their impact on the projectile element along tangent.

The execution of the cross-sectional area of the gas outlet is less than the cross-sectional area of the projectile element prevents the possibility of placing the projectile element in the gas outlet, and also allows you to control the energy of the action of powder gases on the projectile element due to the possibility of adjusting the cross-sectional area of the gas outlet depending on the shape and size of the projectile element, which expands the arsenal technical means for KSOOI.

The implementation of the cavity to accommodate the projectile element in the form corresponding to the shape of the projectile element allows you to expand the arsenal of technical means for KSOOI, as well as optimize the calculation of the energy of the action of powder gases on the projectile element.

Thus, the proposed technical solution expands the arsenal of technical means for KSOOI, provides the ability to fire a projectile element with a strictly defined energy and use the chamber for aimed shooting from KSOOI at targets and equally to scare away aggressive animals without lethal consequences. And, very importantly, this product may be purchased without authorization.

The essence of the utility model is illustrated by the drawings, where in Fig. 1 shows a general view of the chamber for KSOOI, in which the cavity for accommodating the missile element has a shape corresponding to the spherical shape of the missile element; in fig. 2 shows a chamber in which the cavity for accommodating the missile element has a shape corresponding to the shape of the missile element in the form of a cap; in fig. 3 shows the chamber, the gas outlet of which is made in the form of channels located along the periphery of the cavity for accommodating a missile element; in fig. 4 shows a section A-A of the chamber in FIG. 3.

The cartridge chamber for KSOOI contains a cavity 1 for accommodating a missile element 2, for example, in the form of a rubber bullet, and a cavity 3 for accommodating a low-pulse source of powder gases 4, for example, a primer, which are interconnected by a gas outlet 5, the entrance 6 of which into the cavity 1 is located eccentrically to the axis this cavity. The projectile element 2 can be, for example, a cap, a spherical bullet, including a rubber one, and the cavity for accommodating the projectile element may have a shape corresponding to the shape of the projectile element. In this case, the cross-sectional area of the gas outlet 5 is less than the cross-sectional area of the projectile element 2 and is calculated depending on the shape and size of the projectile element. The gas outlet can be made in the form of channels 7, the entrances 8 of which into the cavity 1 for accommodating the missile element are located along its periphery.

The device works as follows.

Before firing, the projectile element 2 is driven into the cavity 1 of the chamber. When the trigger is pressed, the drummer is released from the hold and, under the action of the mainspring (not shown), pricks the primer 4. The powder gases from the cavity 3 through the gas outlet 5 (channels 7) through the inlet 6 (8) reach the projectile element 2 and push it out of cavity 1 into the barrel (not shown).
