The invention relates to the Armoury technique, the current models of the collection of miniature fire-arms, specifically - to the cartridges for him.
Collecting miniature operational models of firearms - popular hobby. Today, the gathering of miniature models of arms of different epochs and leading weapons companies not only an interesting and worthy of respect occupation, but also a prestigious one.
Currently masters are made miniature model of weapons of almost all types. Development and manufacturing of cartridges to them is an integral part of the complex.
It is known that for the firing of conventional small arms are used unitary cartridges, whose bullet, propellant charge and a cap knit together through the sleeves (see V. Kirillov, V. M. Sabelnikov, «Ammunition, small arms, Feet, Central research Institute of the information, 1980, p.86).
The disadvantage of industrially produced unitary cartridges is the impossibility of their application in miniature models of firearms. You want their miniaturization.
Known cartridge for miniature models of firearms (patent №2399013 «Cartridge for miniature models of firearms», IPC F42B 5/00) prototype.
The disadvantage of this cartridge is the impossibility of its application in the current model miniature automatic firearms, which require the automatic reloading ammo while shooting.
The technical goal of the invention is to create and to approximate the design of combat Chuck safe copy of a miniature cartridge, allowing automatic firing of a miniature model of automatic weapons, not complicating mechano-kinematic scheme of the miniature arms.
The goal of the project is achieved by Chuck for a miniature automatic weapon made of telescopically interconnected two cases, the inner sleeve is equipped with a rim for extraction cartridge in its cavity is placed propellant charge, and in piston fixed diameter equal to the diameter of the inner cavity of the outer sleeve, interacts with the simulator bullets fired, at the mouth of foreign liners in the coaxially made cylindrical channel and into the back of the outer sleeve is equipped at the level of the slice inner sleeve at its extended position, holes.
The essence of the invention is illustrated by drawings, where 1 is depicted in the context of miniature cartridge placed in the chamber of the barrel miniature automatic weapons and a locked gate, with whom he interacts in the process of automatic fire.
Cartridge contains telescopically interconnected socket 1 and socket 2, propellant powder 3, 4 piston, a simulator of bullets 5, cylindrical channel 6, vents 7, 8. The cartridge is placed into the chamber of the trunk 9 and locked gate 10.
Figure 2 shows the location of elements of a cartridge in the time of the shot.
Cartridge for automatic firing of the current model of a miniature firearms works as follows. After the break the capsule in the cavity liners 2 propelling charge 3 creates a high pressure, which pushes the anchor at the mouth of the sleeves 2 piston 4 which, compressing the air in the cavity liners 1, sent a cylindrical channel 6 to the simulator bullet 5, throwing her out of the trunk channel 9. Occurs shot. The telescopically connected with pocket 1 sleeve 2, interacting with a gate 10, moves it to the back position, which is in the process of their movement, being in engagement with a rim 8, carries out extraction sleeves and then moving forward under the influence of recoil, produces reloading of the weapon. Excess pressure drop through the vent holes 7, provides required for safe firing power of muzzle energy. Then this cycle is automatically repeated.
The invention allows to create a new collection of miniature firearms - automatic.
Cartridge manufactured and tested with positive results in the Tula LLC firm «Micron manufactures miniature operational models of small arms firearms, and now automatic.
Cartridge for the current model miniature firearms, containing housed in a propellant charge and element interacts with the simulator bullets fired, wherein it is made of telescopically interconnected two cases, the inner sleeve is equipped with rim extraction cartridge in its cavity is placed propellant charge, and in fixed piston diameter equal to the diameter of the inner cavity of the outer sleeve, interacts with the simulator bullets fired, at the mouth of foreign liners in the coaxially made a cylindrical channel, and in the back part of the outer sleeve is equipped at the level of the slice inner sleeve at its extended position, holes.
