FIREARM Russian patent published in 2003 - IPC

FIELD: military equipment, in particular, ammunition and firearm. SUBSTANCE: the method for minimizing the misfires of the firearm or reducing of their aftereffects is accomplished by provision of at least each locking shell from the row of shells enclosed in the barrel by the sealing part located around the tapered section of the shell body and moving together with it for expansion and getting into a tight contact with the barrel. The sealing part comes out of contact with the barrel by forward movement in response to a misfire or hangfire so as to provide a by-pass channel for inflammation of the propellant charge connected with the next head shell. The assembled barrel has a great number of shells placed in the barrel in its axis together with the propellant powder charges, packing between the shells and barrel to prevent a breack-through of gases. Each shell has a striker installed for action of the propellant powder charge on it for provision of movement with an acceleration. EFFECT: minimized misfires. 11 cl, 6 dwg
