Description

The utility model relates to weapons technology, namely to pneumatic weapons with compressed gas pre-pumping (PCP pneumatics) designed for firing bullets.

From the prior art, pneumatic weapons with pre-pumping for firing bullets are widely known, for example, the Kral Arms Puncher Auto rifle (V. Lopatin. Self-loading and not only. Kral Arms PCP rifles. // Kalashnikov. Weapons, ammunition, equipment - 10/24/2019 https://www.kalashnikov.ru/samozaryadnye-i-ne-tolko/ ), as well as the pneumatic weapon described in document US20100031943, IPC F41B11/00, publ. 02/11/2010. Devices known from the prior art include a barrel, a high-pressure reservoir, and a filling port. The refueling port is made in the pressure tank in such a way that when refueling, the barrel bore remains open and if safety rules are violated, an accidental shot is possible. Another disadvantage of the known pneumatic weapons is the need for systematic cleaning of the filling port due to clogging during operation of the weapon.

As a prototype, a pneumatic weapon with a preliminary pumping for firing with CARDINAL bullets, manufactured by A + A LLC (see passport PK-00.000 PS, pneumatic pistol model CARDINAL, TU 25.40.14.-028-52524051-2019 ) https://pnevmat24.ru/image/catalog/files/goods/manuals/cardinal_manual.pdf), containing a barrel with a channel and a muzzle, a high-pressure reservoir mounted above the barrel, a filling port. The filling port is made in the high-pressure tank from the side of the muzzle. The filling of the pressure tank is carried out through the filling port, in which a fitting is installed connected to the filling station.

As a disadvantage of the prototype can be noted the possibility of a shot in the process of refueling a high-pressure tank in violation of safety rules. In addition, the filling port becomes clogged during the operation of the weapon and needs to be cleaned regularly.

The purpose of the utility model is to improve the operational characteristics of weapons.

The technical result consists in increasing the safety and ease of maintenance of the weapon by installing a high-pressure reservoir around the barrel and making the filling port on the side of the muzzle coaxial with the barrel bore, as a result of which, during the refueling process, the barrel bore is closed with a fitting, and during operation, with each shot - self-cleaning filling port.

The problem is solved due to the fact that the pneumatic weapon with pre-pumping for firing bullets contains a barrel with a channel and a muzzle, a high-pressure reservoir, a filling port made from the side of the muzzle, in which, according to the utility model, the high-pressure reservoir is installed around the barrel, and the filling port is made coaxially with the channel.

The essence of the utility model is illustrated by the following drawings:

fig. 1 - general view of pneumatic weapons;

fig. 2 is a general view of a pneumatic weapon in the process of refueling with a fitting installed in the filling port.

The pneumatic weapon contains a barrel 1 and a high pressure tank 2 (Fig. 1). The barrel 1 is made with a channel 3 and a muzzle 4. The high-pressure reservoir 2 is installed around the barrel 1. Further, the claimed weapon will be considered on the example of the execution of the high-pressure reservoir 2 with a plug 5 (Fig. 2) installed from the side of the muzzle 4. In the plug 5 is a filling port 6, the axis of which coincides with the axis of the channel 3. The plug 5 has a socket 7 and a hole 8. The hole 8 is connected to the socket 7 and the filling port 6. The entrance of the socket 7 is located on the side of the internal cavity of the high pressure tank 2. A nipple is installed in the slot 7 with the possibility of passing compressed gas into the high-pressure tank 2 when refueling the weapon. The nipple is made in the form of a screw 9 with a conical head 10. A sealing ring 11 is placed on the head 10 of the nipple screw (Fig. 2).

Hole 8 is designed to direct the compressed gas coming in the process of refueling from a filling station (not shown) through fitting 12 to socket 7.

The sealing ring 11 ensures the tightness of the high pressure tank 2 at the end of the refueling of the weapon. The sealing ring 11 is made of an elastic material, which can be used in various types of rubber, polyurethanes and elastomers.

It is also possible to perform the claimed weapon, in which the high-pressure tank 2 is made in the form of a single part, and the socket 7 and the hole 8 can be made in the end part of the tank 2.

In another embodiment, the filling port 6 is made in the channel 3 of the barrel 1. With this design, the socket 7 can be made in a plug, and the hole 8 is made in the barrel 1 and in the plug.

Due to the installation of the high-pressure reservoir 2 around the barrel and the execution of the filling port 6 coaxially with the channel 3 from the side of the muzzle 4, when servicing the weapon, the user is spared the operation of regular cleaning of the filling port 6, since it is self-cleaning with each shot.

Refueling pneumatic weapons with pre-pumping for firing bullets is as follows.

If it is necessary to fill the declared weapon, fitting 12 is installed in the filling port 6 (Fig. 2). Fitting 12 is connected to a filling station (not shown). Through the fitting 12, the compressed gas first enters the hole 8, which directs it to the socket 7 and through the thread of the screw 9 of the nipple, the compressed gas passes to the head 10 of the nipple. Under the pressure of the incoming compressed gas, the ring 11 increases in diameter, rises along the cone of the nipple head 10 and passes the compressed gas into the cavity of the high pressure tank 2 (Fig. 2). In the process of refueling, fitting 12 hermetically closes channel 3, due to the fact that under the influence of compressed gas coming from a filling station (not shown), the sealing rings of fitting 12 are deformed, tightly adhering to the side walls of the filling port 6. Due to the fact that during the filling process channel 3 is hermetically sealed from the side of the muzzle 4 by fitting 12; in case of an accidental shot, the bullet, moving along channel 3, will work like a piston, compressing the gas in channel 3 in front of the bullet. At the moment when the pressure in the sections of channel 3 before and after the bullet is equalized, the bullet will stop.

Upon reaching the required pressure in the cavity of the tank 2, which is determined using a filling station pressure gauge (not shown), the supply of compressed gas is stopped. The ring 11 under the action of the gas pressure of the high pressure tank 2 is compressed and lowered along the cone head 10 of the nipple to its original position, ensuring the tightness of the high pressure tank 2 - plug 5 system. , which will allow you to remove the fitting 12 from the filling port 6.

For refueling the declared weapon, a standard fitting used for refueling pre-inflated pneumatic weapons can be used.

Airguns with a pressure reservoir around the barrel and a filling port aligned with the bore on the muzzle end provide safety when filling the pressure reservoir by closing the passage during the filling process, and eliminate the need for regular cleaning of the filling port, which enhances weapon performance.
