Definitions

  • This invention relates to improved semi-automatic firearms, especially gas-taking systems for such rifles.
  • This piston under the pressure of the gases moves in said cylinder by communicating a thrust on a sleeve equipped with one or more rods which return backwards all the moving parts which perform the different ejection functions of the sleeve fired, resetting the firing system as well as supplying the barrel with a next cartridge.
  • the above system comprises a return spring acting on said piston in order to replace it during the actions of said set of moving parts.
  • the invention relates to improvements to such a gas-taking mechanism in which all the parts are arranged co-axially and external to the magazine tube which contains the cartridges to be drawn.
  • the gas takeoff mechanism also includes a control valve or pressure relief valve held in position by a spring.
  • This valve is intended to let escape a part of the gases coming from the barrel of the weapon in the event of too great pressure, for example during the firing of cartridges called "Magnum".
  • This gas escape for example through a hole drilled in the side wall of said cylinder, limits the pressure on said piston and avoids reaching too high a speed of movement of said moving parts, which could harm the reliability of the weapon. or lead to excessive wear of moving parts.
  • the invention relates to a regulating gas intake having several new characteristics.
  • a first characteristic according to the invention is constituted by the fact that the pressure relief valve is located in the piston assembly, hence a very simple, efficient and compact construction.
  • valve makes a relative movement relative to the piston and this movement takes place in the same direction and the same direction as the active movement of the piston. hence a reduction in the recoil force.
  • An improved hunting rifle comprises a magazine tube around which is disposed a cylinder whose interior is in communication with the interior of the barrel and in this cylinder and around the magazine tube, on the one hand, a piston capable of move under the effect of part of the propellant gases and being able to cooperate with a sleeve provided with one or more rods capable of acting on all of the moving parts, and on the other hand, a valve regulating or overpressure, springs being provided to control, the return of the sleeve and the regulating valve is characterized in that the regulating valve is located in the piston assembly.
  • the semi-automatic shotgun 1 as shown in Figure 1 is substantially constituted by the barrel 2, the carcass 3, the butt 4, the trigger guard 5 with the trigger 6 and the handguard 7 incorporating the magazine tube 8.
  • a gas cylinder 9 fixed to the barrel 2, incorporating a piston 10 and a regulation or pressure relief valve 11, and a sleeve 12 in contact with said piston 10 and fixed to a rod 13 whose free end is in contact with the assembly 14 of the moving parts of the weapon.
  • the interior of the cylinder 9 is in relation to the interior of the barrel 2 by co-axial orifices, respectively 15 and 16.
  • the sleeve 12 is constantly pushed against the piston 10 by a return spring 17.
  • the piston 10 is substantially constituted by a first tube 18 having towards the front end a portion of smaller diameter 19 in which is formed a circular channel 20 housing two O-rings, respectively 21-22, forming a guide element of the piston 10 in the bore 23 of the cylinder 9 and by a second tube 24 of a larger diameter, the rear end of which comprises a threaded portion 25 with which a threaded ring 26 co-operates.
  • the tubing 24 constitutes with respect to the tubing 18 a flange 27 which can cooperate with the rear end 28 of the cylinder 9 and this tubing 24 also has discharge holes 29, located at the front of this tubing 24.
  • the regulation or pressure relief valve 11 which is arranged co-axially in the piston assembly 10, is constituted by a tube 30 having on the outer surface of the longitudinal grooves 31, this tube 30 being guided by its front part of smaller diameter 32 in the bore 33 of the tube 19 of the piston 10, by the outer surface of the grooves 31 in the bore 34 of said tube 18, by O-rings 35-36 housed in a circular cavity 37 in the tube 30 on the magazine tube 8 and by a support ring 38 for the spring 42 fixed on the rear end of the tubing 30 in the bore 39 of the tubing 24 of the piston 10.
  • the tube 30 also has a stop 40 capable of cooperating with a circular surface 41 of the piston 10 under the influence of a return spring 42 housed in the tube 24 of the piston 10 between the support ring 38 bearing on the rear part of the tubing 30 of the valve 11 and said ring 26 fixed in the tubing 24 of the piston 10.
  • the force exerted by the spring 42 on the valve 11 is adjustable by means of the ring 26 which can be moved relative to the tube 24 of the piston 10.
  • part of the propellant gas from the cartridge is derived from the barrel 2 through the orifices 15-16 towards the piston 10 thus causing the displacement of the latter with the effect of a push on the sleeve 12 and thus on the rod 13 which then acts with its free end on all of the moving parts 14 which carry out, in a manner known per se, the various functions of ejection of the drawn socket, the resetting of the firing system and the supply in the barrel chamber of the next cartridge, after which, via the return spring 17 the piston 10 will be replaced.
  • the rifle according to the invention has the advantages of improved sealing; a construction simple, efficient and compact, and a movement of the piston 10 and of the valve 11 in the same direction and the same direction, thereby reducing the recoil force.
  • the sealing elements in particular the O-rings can be replaced by other sealing systems, for example grooves; that the cylinder / piston / valve assembly may be located either, as described above at the periphery of the magazine type, or be located in front of the tube, or on the side of the tube, or even in place of a portion of this tube; that the spring which holds the valve 11 against the piston 10 may be different from a conventional compression spring, etc.
