Description

The gun belongs to handguns and is intended to equip the paratrooper in landing operations as "manual artillery" when firing at long-range targets, and for close targets it is an alternative to a grenade launcher.

Similar weapons are known from a patent source. So, according to patent No. 2235260, small arms have a locking mechanism designed for a powerful cartridge; Patent No. 2239759 describes a method of operating an automatic small arms for firing powerful ammunition; Patent No. 2192595 has a mechanism for regulating the gas flow of automatic weapons; Patent RU 2199708 describes a shutter for an automatic weapon.

As a prototype, patent No. 2186310 was chosen - a mechanism for locking the barrel of an automatic weapon, which contains a bolt with a striker movably mounted in the receiver and a bolt frame with a return spring that contains similar nodes and parts with the proposed solution to the problem, but differs significantly in terms of the final goal, for example, the possibility of landing, which served as a tool in the mountains, where it is not possible to support the landing with artillery and BMD, while the economic goal is also pursued - provisions

This goal is achieved, according to the author, due to the fact that the barrel is equipped with an annular groove in which the spacer ring is placed with a gap, and the shell, from the end, is equipped with a capsule, while the spring-loaded shutter has a cavity in which the rod is coaxially placed at the end which on the thread is secured a striker with a disk reflector and a cutter, which is a spring-loaded sleeve that enters the gap between the rod and the valve body, as well as a spring-loaded piston and washer, which are fixedly mounted on the rod, the latter interacts with the spring nennoy latch, in the longitudinal groove of the rod which is the shoulder of the two shoulders of the trigger lever, and the other end of the rod is equipped with a trigger, while the shutter cavity is divided into cameras; combustion, dispenser and air, the latter through the hole in the shutter, the groove, nipple and tube in the bed communicates with the air cavity of the explosive container located in the handle, and the chamber until the jam, through the hole in the shutter, the groove of the nipple and tube communicates with the cavity of the explosive capacities.

The complex design of the gun-projectile system can be simplified by detonating the explosives electronically - with the spark.

The gun contains:

the bed - 1 (since it relates to hand weapons), the barrel - 2, the handle - 3, the bolt - 4, the rod - 5 (telescopic), the firing pin - 6 (with a disk reflector) - cut-off, sleeve - 7 (cut-off), spring - 8 (shutoff), piston - 9, spring - 10 (piston), nut - 11 (shutter), washer - 12 (control), washer - 13 (support for the shutter spring), spring - 14 (shutter), trigger - 15 , latch - 16 (locking), two-arm lever - 17 (trigger), nipple - 18 (for explosive), nipple - 19 (air), pipe - 20 (for explosive), pipe - 21 (air), capacity - 22 (for explosive) of that substance), a ring - 23 (serves to fix the projectile in the barrel), a screw - 24 (with which two parts of the telescopic rod are connected), a capsule - 25, a combustion chamber - “a”, a metering chamber - “b”, an air chamber - ”c”, slot groove - ”d” (on the rod), hole - ”e” (for taking in explosive), hole - ”f” (for taking in air), groove - ”h” (for delivering explosive) , groove - ”m” (for air supply), clearance - ”k” (between the stem and the body of the shutter), groove - ”L” (longitudinal groove in the latch rod), hole - “h” (damper), window - ” t ”(in the shutter to accommodate I latches), the groove is “q” (to place the spacer ring, which strictly fixes the position of the projectile relative to the end face of the shutter).

Gun mechanism

In FIG. 1 shows the initial position of the mechanism of the unloaded gun: the barrel is empty (conditionally), the projectile is located in the window of supply of ammunition and props the bolt.

The gun is charged per shot manually using the trigger 15 by moving the rod 5 to the right, and through the rod and shutter 4. In this case, the springs 8, 10 14, respectively, of the sleeve 7 of the piston 9 of the shutter 4 are compressed. FIG. 2 shows the position of the mechanism in the extreme right position, locked by means of the washer 12 by the latch 16. When moving the rod 5 and the shutter 4 from the extreme left position to the extreme right position, the piston 9 also moves relative to the shutter 4 to the right, while creating an “C” in the air chamber overpressure, which through the hole "f", groove "m", nipple 19, tube 21 is transferred to the air chamber of the explosive container 22 - BB - this creates the primary manual pumping of the container 22. At the same time from the tank 22 explosive wheelhouse 20, nipple 18, groove ”n”, hole ”e” enters the vacuum cavity of the dispenser ”b”. Due to the pressure difference in the tank 22 and the dispenser "b", the dispenser "b" is measured to fill up with explosive, which is carried out during the passage of the shutter 4 above the groove "n". In the extreme right position, the shutter-rod system is locked through the washer 12 with a latch 16.

To fire the trigger, the trigger 17 is pressed, which is a two-arm lever, which with one shoulder enters the longitudinal groove “L” of the latch rod 16 and moves it down, both the stem 5 and the shutter 4 are unlocked. Under the influence of the springs 14, 10, 8 the shutter 4, the piston 9 and the sleeve 7 are moved to the left. In this case, a vacuum is created in the air chamber of the chamber “c”, which is filled with air through the opening “h”, and in the cavity of the dispenser “b” the piston 9 creates pressure, while the explosive is displaced through the gap “k” and pushes the sleeve 7, as shown in FIG. 3. The combustion chamber ”a” is filled with explosive. As soon as the piston 9 reaches the stop, pressure will drop from the metering side “b” in the gap “k” and the spring 8 will slide the sleeve 7 into the gap “k”, interrupting the communication between the combustion chamber “a” and the metering chamber “b”. At this time, the firing pin 6 is pierced by the capsule 25 - an explosion occurs, the shock wave of which hits primarily the firing pin 6 and the disk reflector, which moves the rod 5, the piston 9, the cutter sleeve 7 and the shutter 4 to the right to the stop. After the rollback of the rod-gate system to the left, the latch 16 through the washer 12 blocks both the rod 5 and the valve 4.

When the trigger 17 is pressed, automatic bursting is carried out.

Description of drawings

The drawings schematically depict:

in FIG. 1 is a longitudinal section of an unloaded gun: there is no projectile in the barrel, the shutter and rod are in the extreme left position, the cutter sleeve has blocked the message between the combustion chamber and the batcher, the projectile is in the munition supply window;

in FIG. 2 - longitudinal section during charging: shutter and rod are in the extreme right position; springs of the sleeve (cutter), piston and shutter are compressed; the latch is in the shutter window and blocks the movement of the washer (control) of the rod; the shutter is ready to push the shell into the barrel;

in FIG. 3 is a fragment of FIG. 1 after pulling the trigger (shown schematically): the latch drops down; the shutter, rod and shutter bushing under the action of their springs are moved to the leftmost position; the piston forces the explosive into the combustion chamber. As soon as the piston displaces a completely explosive substance from the metering chamber, the pressure in the gap will cease and the cut-off spring will block the message between the combustion chamber and the metering unit;

in FIG. 4 is a section AA in FIG. one;

in FIG. 5 shows a single-acting shutter locking device, the location of which is conventionally shown by the unit 1 in FIG. 1. Since the locking device is well known and does not represent the subject matter of the invention, it is therefore not described, but is shown schematically in FIG. 5.
