AUTOMATIC DEVICE FOR SHOOTING WEAPON OF LIGHT, AVERAGE AND HEAVY CALIBRE

摘要

The invention relates to the automatic shooting weapon and can be used in the Armed Forces and other power structures.The purpose of the invention is to establish a constructively new weapon scheme allowing to sharply increase range of a shooting effect on the enemy.It may be achieved by applying a mechanism for dynamic performance of weapon parts to the constructive assembly scheme based on the use of power of gases kicked off from the barrel channel. This mechanism is rigidly connected to the breechblock frame with rack pinion (chain or cable) reciprocating mechanisms. The breechblock frame constructed in a special way makes it possible to toughly block up the barrel together with the breechblock where support elevators are set into on the cylindrical basis. The use of enhancements in the percussion and trigger mechanism by applying the trigger frame make it possible to fire both in a single and an automatic manner.In making a shot by means of such a new automatic device for light, average and heavy caliber, offered in the invention, there appears concentration of power of powder gases to make a bullet accelerated that excludes:1) in submachine-guns - loss of power to impart dynamics to performance of free and half free breechblocks by toughly blocking up the barrel channel;2) in tommy-guns - powder gas withdrawal to reload before the bullet leaves the barrel channel and to put in action weapon automated mechanisms after the gas effect on the bullet on inside the barrel due lo the power of kicked off powder gases making effect on the mechanism, which provides the breechblock movement forward-backward through the reciprocating mechanism.This will allow:- to increase the initial bullet speed: to use the power of moving component of the device towards the opposite side of the kick for its compensation, and this is likely to result in the increase of the accuracy of weapon hits;- to improve the efficiency of ammunition available;- to reduce weapon weight due to optimization of the assembly scheme.
