Definitions

  • the present invention relates to a special barrel for direct-percussion grenade-launchers.
  • Grenade-launchers wherein the barrel performs the task of containing the burst gases, or wherein the task of the barrel is of guiding the projectile.
  • the barrels used in the grenade-launchers known from the prior art have a length much longer than the length of the cartidge, or of the cartridge chamber.
  • the purpose of the present invention is to provide a barrel for grenade-launchers which is of a reduced size, with simultaneously being strong, and making it possible the energy generated by the burst gases of a cartridge to be globally exploited, and being furthermore capable of expelling the cartridge without using mechanical devices.
  • a barrel for grenade-launchers which is characterized in that it comprises an external cylindrical shell, open at one end, and provided with a bore for a percussion pin at its other end, with said one end being provided with an inner screw-threaded portion; inside said cylindrical shell a cylindrical hollow sleeve can be inserted, which is provided at an end with a screw-threading, which can be coupled with said screw-threaded portion of said external shell, under said one screw-threading on the side wall of said sleeve at least one couple of through-­ bores being provided, from each of said bores a milled groove extending downwards in a longitudinal direction, with each one said milled grooves being connected with a shaped bottom of said sleeve, said sleeve bottom being provided with a second couple of through-bores in order to connect said milled grooves with the interior of said sleeve; and with a further central bore for the passage of said percussion pin.
  • a barrel according to the invention is generally indicated, which barrel is constituted by an external shell 11, and an internal sleeve 12.
  • the external shell 11 is provided with an upper screw-threading 13, and, through its bottom, with a bore 14 for the passage of a percussion pin 15.
  • the internal sleeve 12 is provided with an upper screw-threading 16, which can be coupled with the screw-­threading 13, and immediately under the screw-threading 16, two bores 17 and 18 are provided in diametrically opposite positions. From the bores 17 and 18, two respective milled grooves 19 amd 20 extend, which reach a shaped bottom 21 of the sleeve 12. The bottom 21 is provided in its turn with two milled grooves 22 and 23 connected with two through-bores 24 and 25.
  • a further through-­bore 26 is provided for the passage of the percussion pin 15.
  • the barrel 10 is used as an expansion chamber for the burst gases. and such a barrel 10 is of dimensions at least equal to those of a cartridge (not shown in the figures), so as to enable the shell case to expand during the deflagration. Subsequently, thanks to its elasticity, the shell case shrinks, and can be later on ejected by means of the recovery of the gases.
