Description

The invention relates to weapons technology and can be used in shooting sports, in the army and in law enforcement.

A known PCA revolver, made according to the traditional scheme with a hinged left drum. The barrel is equipped with a bar, as well as a streamlined tide-pencil case for the ramrod extractor (S.L. Fedoseev, “History of weapons, pistols and revolvers in Russia”, Moscow, ACT, Astrel, 2003, pp. 54, 55, appendix 1) .

To tilt the drum, you need to push forward the latch on the left side of the frame, and to eject the spent cartridges - press the head of the axis of the extractor. The drum is equipped with a clip of the original form, made of spring steel.

The correct position of the drum in the frame before the shot is provided by the drum retainer (latch), however, unlike other systems, in the PCA the retainer is mounted in the form of a swinging lever in the upper part of the frame, i.e. significantly closer to the war chamber. Reducing the length of the shoulder between the stopper point of the latch and the axis of the war chamber significantly reduces the play of the drum relative to the barrel, better ensures alignment of the chamber and the bore, reduces the load on the parts of the trigger mechanism.

The latch is moved up due to the technical capabilities of production. The open trigger has a helical coil spring of twisted wire, rebound and blocking forward movement after firing. When fired, the trigger strikes the inertial hammer mounted in the frame.

If the drum is not rotated, the lock of the trigger does not allow him to reach the drummer. A fuse in the form of a vertical slider locks the firing pin until the trigger is fully depressed.

This revolver consists of many parts requiring high precision manufacturing. It is bulky due to the drum, has a small number of charges, no more than 5-6 and the reload speed is low.

Closest to the claimed technical solution is the PM pistol, acting on the basis of the recoil of the free shutter-casing. The return spring is worn directly on the barrel: with a relatively low combat rate of fire and a short barrel length, its heating has little effect on the properties of the spring. The ejector is mounted openly in the groove of the shutter-casing behind the window, the headlight mechanism - with an open trigger and a two-armed leaf war spring located in the handle. The lower bend of the mainspring serves as a magazine latch (S.L. Fedoseev, “History of weapons, pistols and revolvers in Russia”, Moscow, ACT, Astrel, 2003, p. 77, app.2).

The trigger has combat and safety platoons. An inertial hammer is mounted in the shutter. The trigger rod has a cocking lever at the end, which also serves as a disconnector. The presence of a special trigger tooth allows self-cocking. Descent - with a warning, i.e. after the preliminary free movement of the trigger, the shooter feels an emphasis, after which a short force is sufficient for the descent. In the pistols of the first releases, the trigger had too much free play, and his choice led to a significant loss of aiming. Over time, this shortcoming has been eliminated. A safety catch located in the back of the shutter locks the trigger in the up position and engages the shutter with the frame.

It also consists of many parts requiring higher accuracy than the revolver manufacturing. Very stringent requirements for the quality of ammunition, while increasing the power of ammunition, requires a great deal of complexity in the design.

When firing from such a pistol, a delay or stopping of firing may occur, associated with poor-quality ammunition, sticking a cartridge during firing, and non-ejection of a cartridge.

A device of 7.62 mm turret cartridge with a shell bullet.

The closest is a 9 × 18 PM cartridge to Makarov’s pistol. Like the previous cartridge, it contains a thin-walled cylindrical sleeve with a central igniter capsule, a charge of smokeless powder and a bullet in a tompak shell protruding beyond the sleeve (S.L. Fedoseev, “History of weapons, pistols and revolvers in Russia”, Moscow , ACT, Astrel, 2003, pp. 6, 7, appendix 3).

When using weapons at short ranges, pistol and revolving cartridges are made relatively low-power (from 40 to 900 J), have light blunt-pointed bullets with a transverse load (weight to cross-sectional area) up to 20 g / cm ² . Ammunition is loaded with rapidly burning smokeless powder.

The objective of the proposed technical solution is to create a powerful compact combat, gas or traumatic pistol, including an ultra-small, more technological in production, cheap and reliable and ammunition for it.

This goal is achieved due to the fact that the ammunition, made in the form of a chamber-cartridge, containing a housing and a charge, while the housing of the chamber-cartridge is made through, bore under a standard cartridge of a given caliber, or bored from one side under a lightweight bullet of a given caliber, and on the reverse side it is squandered under a blank building cartridge of a smaller caliber; a gun with ammunition according to claim 1, containing a body, a barrel, a trigger, a trigger, a receiver and a magazine equipped with camera cartridges, the receiver being rounded at the top and equipped with a cam cartridge lock, ejector button and a window for throwing out the cartridge chamber.

The fact that the receiver has a rounding in the upper part and is equipped with an ejector key and a lock in case of unforeseen inflation of the chamber, it does not fit into the radius of rounding of the receiver and, under the pressure of the next chamber, simply falls out of the receiver window. And does not cause delays when shooting.

The magazine’s equipment with cartridge cartridges provides the main and significant differences of this pistol from revolvers and automatic pistols in that it has attached expendable chamber-cartridges, each case of which acts as a charging chamber, unlike inseparable 5-7 chambers in the revolver drum or one in the gun.

The camora cartridge comes from a pistol-type magazine to a cut of the barrel, as in a revolver when the drum rotates, and after a shot is thrown out of the pistol as in automatic pistols.

The implementation of the chamber-cartridge from a cylindrical body, the thick-walled body of which acts as a charging chamber, and the charge makes it possible to make the ammunition universal and place various charges in the body, for example, the body is cylindrical, deaf at one end, with a seat for installing the capsule over which is located gunpowder and a pressed bullet; the casing of the chamber-cartridge is made through, bore under a standard cartridge of a given caliber, in which a standard cartridge is located; the casing of the chamber-cartridge is made through, bored from one side under a lightweight bullet of a given caliber; on the reverse side it is bored, for example, under a single construction cartridge of a smaller caliber.

This gun is much simpler than a revolver and much simpler than an automatic gun, due to the lack of a drum, rotating and fixing devices, and the ejector shutter.

Since all parts (except the barrel) have large processing tolerances, precise and high-precision equipment is not required, the gun is extremely technological and easy to manufacture.

The gun is not sensitive to contamination. It can work without lubrication, is not sensitive to low temperatures, when shooting, the same type of chamber chambers are used, but with different charges, so the scope is very wide.

Camora cartridge is a universal ammunition that allows you to use any equipment. The gun has all the best qualities of revolvers: trouble-free, easy to maintain, like a revolver should have a high accuracy. Like automatic pistols, it quickly reloads its clip.

You can use very powerful cartridges (for example, from "Mars"). With all this, it remains very compact and simple, unlike the Mars. In general, with the same barrel length, it is 1/3, or even half shorter than revolvers and pistols of the same caliber.

Based on this ammunition, you can create an ultra-small pistol 80-85 mm long, superior in power to the usual "Makarov". With all this, it remains very compact and simple, unlike the Mars. In general, with the same barrel length, it is 1/3, or even half shorter than revolvers and pistols of the same caliber, superior in power to the usual Makarov.

It is possible to create gas and traumatic pistols much more compact than the famous "Wasp", simpler to manufacture, cheap and reliable.

Perhaps having a bullet, independently recharge the chambers depicted in Figure 3.

Ammunition can be used in heavy machine guns and small-caliber automatic guns.

The drawings show a gun and ammunition for it, where in Fig. 1 is a sectional view of the gun, in Fig. 2 is a section along AA, in Fig. 3 is a proposed cam-cartridge, in Fig. 4 is an embodiment, cam-cartridge with a standard cartridge, in FIG. 5 - option, short-chamber cam-cartridge with a lightweight bullet and a single cartridge of a smaller caliber.

Figure 1 shows the housing 1, barrel 2, cam-cartridges 3, trigger 4, trigger 5, receiver 6, magazine 7.

Figure 2 shows a section along aa, where the rounding of the receiver 8, the ejector key 9.

Figure 3 shows the proposed chamber-cartridge 3, loaded with a bullet 11, gunpowder 12, the capsule 13, and the body of the chamber-cartridge 16.

Figure 4 shows a variant, the chamber-cartridge 3, charged with a standard cartridge 15, the housing of the chamber-cartridge 16.

In FIG. 5 shows an embodiment, a camcorder cartridge, short-loaded, loaded with a lightweight bullet 11 and a blank cartridge 14, the housing (tube) of the camcorder cartridge 16.

The gun is made as follows.

The gun consists of a housing 1, on which the barrel 2 is located, with a receiver 6, a double-action trigger mechanism containing a trigger 4, a trigger 5, and a single or double-row pistol-type magazine. Bottom to the receiver 6 attached store 7. The gun does not have a shutter, its role is played by the wall of the receiver 6.

Ammunition is made as follows.

The proposed ammunition for the described pistol is the “camora-cartridge” (charging chamber), made of a cylindrical body 16 with thick (2-3 mm) walls with a length of 2.5-4 cm and a charge.

Figure 3 shows the proposed cam-cartridge 3, where the housing 16 is made deaf from one end, in which there is a seat for installing the capsule 13, over which the gunpowder 12 and the pressed bullet 11 are located.

Figure 4 shows a variant where the housing 16 of the chamber-cartridge 3 is made through, bore under a standard cartridge of this caliber, in which a standard cartridge 15 is located.

Figure 5 shows a variant where the housing 16 of the chamber-cartridge 3 is made through and bored from one side under a lightweight bullet of a given caliber. On the reverse side, it is bored, for example, under a single construction cartridge of a smaller caliber. This short-bore camcorder cartridge can be used for training firing.

The gun and its ammunition operate as follows.

The gun is equipped with a chamber-cartridge 3 located in the receiver 6. When fired, the charge 12 through the barrel leaves the housing 16 of the chamber 3, which is thrown to the right with the ejector button 9, through the window of the receiver 6.

When you press the trigger 5 cock 4 and pulls the lock 10, from the side of the barrel 2, which contributes to a better retention of the chamber 3 against the cut of the barrel 2.

After hitting the trigger 4, the trigger 5 by inertia continues to move backward with the finger of your hand, pushes the latch 10 and pushes the ejector key 9, which ejects the shot chamber 3, while cutting off the advancement of the next chamber 3 with its lower part.

When the trigger 5 is returned, the ejector key 9 is recessed into the body and the next cam 3 rises against the cut of the barrel 2 and is held by the rounding of the receiver 6 and the spring pressure of the magazine 7. The cam 3 in the receiver 6 has no play in either the vertical or horizontal plane, unlike the drum in the revolver, which provides a good obturation.

In FIG. 3, 4, 5 depict the options (charge) of the equipment, both smoke and smokeless powder 12 and any projectile, for example, a bullet 11 in the shell without a difference in weight, a blank cartridge 14, a standard cartridge 15, shot, tear, paint, etc. .d.

The final processing of the receiver 6 and the barrel 2 is a single tool. This ensures the highest accuracy of coincidence of the barrel 2 with the chamber-cartridge 3, which comes from the magazine 7 when it is installed in the gun. Change stores exactly like automatic pistols.

The technical result is the creation of a new powerful compact combat, gas or traumatic pistol, including an ultra-small, more technologically advanced in production, cheap and reliable due to the fact that the gun contains a body, barrel, trigger, trigger, receiver, magazine, while the receiver has a rounding in the upper part and is equipped with an ejector key, a latch, the magazine is equipped with cartridge chambers, the thick-walled case of which acts as a charging chamber in which the charge is placed.
