RU226058U1 - Sturov muzzle brake-silencer-flame suppressor for small arms - Google Patents

Abstract

The utility model refers to removable muzzle devices to reduce recoil, sound, and flame visibility when fired. The muzzle brake-silencer-flame arrester of a shot has a body with end parts, on one of them there is an adapter with a hole for the passage of a bullet and a threaded part for fastening to the muzzle of a small weapon, on the other end part there are holes for the exit of the bullet and holes for the exit of powder gases from DTGP. Inside the body there is a shell with holes for the passage of powder gases through them, reflectors are installed inside the shell, dividing the internal volume of the shell into compartments and directing powder gases from the center to the holes of the shell, the reflectors are made with central holes, the area of the holes is maximum in the reflector on the muzzle side and decreases in each subsequent reflector to the area of the hole for the passage of a bullet through the outermost reflector. DTGP parts can be made by stamping and have an oval shape; DTGP can have a collapsible design for servicing and replacement of damaged components.

Description

The utility model relates to muzzle braking devices, silencers, and flame arresters for small arms and small-caliber guns.

A muzzle device is known (RF patent No. 2345305), containing a housing with installed in it: a centering element, a separator sleeve, a separator with a bullet valve, consisting of sequentially arranged elements that form an expansion chamber between themselves and the wall of the housing.

The disadvantage of this device is its low survivability when automatically firing in a continuous long burst.

A closed-type muzzle brake is known (patent RU 755929), which contains an outer cylindrical shell, closed at the rear end by an elongated cover with a splitter attached from the inside, which is attached to the muzzle of the barrel.

The disadvantages of this DTZT include the preservation of a weakened shot sound and insufficient flame suppression.

The technical objective of the proposed utility model is to improve serviceability, significantly reduce recoil, sound, and flames when firing in long bursts.

To significantly increase the internal volume of the muzzle brake-silencer-flash suppressor (DTGP) while maintaining an acceptable length of the DTGP of the sighting devices existing on small arms, the DTGP has an oval shape of the main cavities of the DTGP.

DTGP has a stamped end oval part 1 with an adapter 2 fixed along the axis of the end part 1 with a central channel for the passage of a bullet when fired and a threaded extension of the channel for screwing onto the barrel of a small weapon.

On the opposite part of the oval body 3 there is a stamped end part 4 with an axial hole for the passage of a bullet when fired and holes for the exit of powder gases from the internal volume of the DTGP.

Inside the housing 3 between the end parts 1 and 4 are fixed: an oval shell 5 along the end part, inside it there are oval reflectors 6 of powder gases. Oval reflectors 6 are made with central oval holes, the dimensions of the oval holes decrease from the end part 1 to the end part 4 to the size of the diameter of the hole for the passage of a bullet in the outer reflector 6.

Reflectors 6 have a shape that ensures the direction of powder gases from the central hole of the reflector 6 to the inner part of the shell 5, bushings 7 are installed between the reflectors 6, the entire DTGP structure is tightened with bolts 8 and wing nuts 9.

When fired, powder gases through a series of decreasing central oval holes in the reflectors 6 affect the reflectors 6 more or less equally; the shape of the reflectors 6 directs the gases to the holes of the shell 5, then into the cavity between the shell 5 and the body 3, then from the cavity between the body 3 and the shell 5 through the holes in the shell 5 behind the outer reflector 6, the powder gases through the holes in the end part 4 exit beyond the internal volume of the DTGP.

The effectiveness of muzzle braking DTGP is due to the almost equal and simultaneous impact of powder gases on the reflectors 6, the change in the direction of the powder gases to the shell 5 by the shape of the reflectors 6.

The effectiveness of reducing the sound of a shot is due to a significant increase in the internal volume of the DTGP due to the design of the body - 3, the end parts 1 and 4, the oval-shaped shell 5, the stepwise passage of powder gases through the holes of the shell - 5, due to the division of the internal volume of the shell 5 into compartments by reflectors 6.

The effectiveness of reducing the visibility of the flame during a shot is due to the direct change in the direction of the powder gases inside the DTGP and the significant internal volume of the DTGP, which significantly reduces the temperature of the powder gases upon expansion in the internal compartments of the DTGP.
