AUTOMATIC SUBMACHINE GUN, IN WHICH THE ENERGY OF RECEIVING IS USED, CONTAINING TWO OPERATING LEVERAGES OF THE TRIGGER, ONE OF WHICH IS RELATED TO THE SINGLE FIRE REGIME, AND ANOTHER – WITH THE MODE OF SHOOTING IN ROUNDS Russian patent published in 2018 - IPC F41A9/55 

FIELD: small arms.

SUBSTANCE: invention relates to automatic small arms, namely to submachine guns. Automatic submachine gun in its composition has a pile, a fixed barrel, a free bolt, an inertia trigger with a spring mechanism, a manual translator of fire regimes with a cam device, a device for recovering the kinetic energy of the shutter, folding cocking cock and front for holding, box-type double-row magazine with asymmetric end edges, a sliding stock with curved guides, a trigger and protection mechanism, a flame arrester. In the production of a shot, the bolt, moving backwards, hits the massive trigger at a point below the center of gravity of the trigger. In this case, the trigger rotates upward, overcoming the force of the spring to the cocked state, while absorbing a significant part of the kinetic energy of the shutter. Rest of the energy is absorbed by the spring recuperator.

EFFECT: technical result is a decrease in the recoil, an improvement in the accuracy of combat, convenience and simplicity in handling.
