Abstract

FIELD: weapon for shooting bullets or shells, in particular, small arms and artillery weapon.

SUBSTANCE: the pneumofire arms has a barrel, means for filling the barrel with compressed fuel gaseous mixture and providing its combustion, having a compressed air supply unit, combustible or fuel mixture supply unit and a shot-start initiator. The weapon makes it possible to use for shooting both the pressure of compressed air and the pressure arising as a result of combustion or fuel or mixture.

EFFECT: simplified construction.

Description

The invention relates to weapons for firing bullets or shells, in particular to small arms and artillery weapons.

Known pneumatic weapons for firing bullets or shells (TSB. Second edition. Volume 33, 1955, p.319, article "Airguns").

Known firearms for firing bullets or shells (TSB. Second edition. Volume 30, 1954, p.497, article “Firearms”).

Known pneumatic guns containing a barrel and means for filling the barrel with a compressed combustible gas mixture and ensure its combustion (see patent RU 2095721 C1, CL F 41 A 1/04, 1997).

However, this weapon has a complex structure and cannot be fired from using a compressed air pressure.

The objective of the invention is the creation of weapons with the ability to provide firing when using both the pressure of compressed air and the pressure resulting from the combustion of a combustible substance or mixture.

The specified technical result is achieved due to the fact that in a pneumatic gun containing a barrel and means for filling the barrel with a compressed combustible gas mixture and ensuring its combustion, the latter contains a compressed air supply unit, a fuel supply unit or mixtures having the possibility of ignition as a result of the supply of compressed air to the barrel, and a shot initiator configured to open the first and second valves at predetermined moments in belt.

In addition, the means for filling the barrel with a compressed combustible gas mixture and providing its combustion has a unit for igniting a combustible substance or mixture, and the shot initiator contains means for starting an ignition unit for a combustible substance or mixture at a given point in time.

Pneumatic guns are equipped with a means for feeding a bullet and a projectile into the barrel, which is made in the form of a container with a piston placed in it, communicating with the internal cavity of the barrel through a third valve, which allows the passage of gas or gas mixture only from the barrel into the container.

The drawing shows a pneumatic gun.

Pneumatic gun contains a barrel 1, a supply unit 2 of compressed air, a supply unit 3 of a combustible substance or mixture, an ignition unit 4 of a combustible substance or a combustible mixture, a container 5, a piston 6, a first valve 7, a second valve 8, a third valve 9, a shot initiator 10 .

Airguns works as follows. A bullet (with or without a powder charge) is directed into the barrel 1, after which the initiator of the shot 10 is launched, opening the first valve 7 and the second valve 8, directing compressed air from the supply unit 2 to the barrel 1 and injecting gaseous or liquid combustible material into it or mixture from the feed unit 3. When a combustible substance or mixture is combusted in the barrel 1 and burns under the influence of compressed air, they self-ignite; when other flammable substances are supplied, their ignition occurs due to ignition using ignition unit 4 upon command from the initiator of shot 10. As a result, the bullet is pushed out of barrel 1.

The initiator of the shot 10 is a mechanical or electromechanical device that opens and closes the valves (or only opens if the design of the valves allows them to be closed by gas pressure in the barrel) and the electric current is passed through the ignition unit 4, made in the form of an electric heating element, or the formation of a spark in the block ignition 4, made in the form of a spark plug. Moments of valve response time (simultaneous supply of air, combustible mixture and ignition; preliminary supply of combustible mixture, etc.) are selected based on the tactical and technical requirements for weapons.
