Abstract

Throwing device of a pneumatic weapon, characterized in that it contains a cylinder with a piston, a barrel connected to the cylinder, and a capsule mounted in the cylinder behind the piston on the side opposite to the barrel.

Description

The utility model relates to weapons technology, in particular, to a throwing device for airguns, and can be used for sports and recreational shooting with standard bullets for airguns.

Known throwing device of a pneumatic weapon containing a housing connected to the barrel, a compressor with a piston and a mainspring and a locking device made in the form of a spring-loaded cylindrical rod in a stepped form (a. St. USSR No. 812112, publ. March 15, 1981).

A throwing mechanism of a pneumatic weapon is known, comprising a cylinder with a piston and a mainspring, on which a cutter is aligned coaxially with the side of the pre-piston volume, and a guide part connected to the cylinder, the inner diameter of which is larger than the diameter of the cutter to form a gap when mating, the gap being throttled for providing constant communication of the volume of the guide part with the pre-piston volume when mating. (a. St. USSR No. 1740965, publ. 06/15/1992)

The closest to the proposed technical solution is a missile device of a pneumatic weapon containing a cylinder with a piston, a barrel with a bullet connected to the cylinder and a rod with a spring mounted under the piston (http://www.air-gun.ru/social/readtopic/1009).

The disadvantages of the known devices is the complexity of their design due to the presence of a large number of exact mates of parts and, accordingly, the complexity of their manufacture. In addition, the disadvantages of the known analogues are the large dimensions of the throwing devices due to the fact that the spring-piston system must have a large volume of air in the cylinder and a powerful spring to create air pressure sufficient to provide a given flight speed of the bullet.

The objective of the utility model is to create a compact propelling device for airguns simple in design and manufacture while maintaining power characteristics.

The technical result consists in simplifying the design of the propelling device, simplifying its manufacture, and reducing the size of the pneumatic weapon.

The problem is solved in that the missile device of an air gun contains a cylinder with a piston, a barrel with a bullet connected to the cylinder, and a capsule mounted in the cylinder behind the piston on the side opposite to the barrel.

The installation of the capsule in the cylinder allows, due to the release of a large amount of gas during ignition of the substance contained in the capsule, and, accordingly, the increase in pressure under the piston, to ensure movement of the piston during firing and compression of air in the cylinder, which moves the bullet in the barrel. The use of the capsule also makes it possible to simplify the design of the throwing device, since in order to ensure the speed of departure of the bullet from the barrel with characteristics similar to the speed of departure from the throwing device having a piston with a spring, a large number of mating parts needed to communicate the movement of the piston, including the compression spring, are eliminated . The absence of parts necessary for communicating the movement of the piston and the presence of a capsule instead of them allows, while maintaining power characteristics, to reduce the dimensions of both the propelling device and the pneumatic weapon as a whole. Simplification of the design of the throwing device allows to simplify its manufacture.

Throwing device airguns shown in the drawing, a General view.

The pneumatic weapon throwing device comprises a barrel 1 with a bullet 2. A barrel 1 is connected to a cylinder 3 in which a piston 4 is installed. A capsule 5 with a highly flammable substance emitting a large volume of gases during combustion is installed in the opposite wall of the cylinder 1 behind the piston 4. The charge of the capsule and the volume of the cylinder are calculated depending on the given bullet departure speed.

The device operates as follows.

During mechanical action on the capsule 5, ignition of the substance present in it occurs and a large amount of gases is formed. Gases create pressure between the cylinder wall and the piston, under the influence of which the piston 4 begins to move. The movement of the piston 4 causes compression of the air in the cylinder 3, which moves the bullet 2 in the bore of the barrel 1. A shot is fired. After the shot, replace the used capsule 5 with a new one - the throwing device is ready to fire.
