Definitions

  • the object of the invention relates to the technical sector of ammunition.
  • the object of the invention is to remedy these drawbacks in a simple, efficient and rational manner.
  • an ammunition of the type comprising that a cylindrical case, one end of which is capable of receiving at least one projectile while the other end has a concentric chamber capable of receiving a cartridge of reduced size.
  • This cartridge is remarkable in that the chamber has, over its entire length, a constant and uniform internal diameter corresponding to that of the cartridge to avoid the rise in high pressure, said cartridge being charged with pyroxilated powder, and receives a primer overloaded with fulminant composition.
  • the said projectile (s) are contained in a bucket element mounted with free sliding and centered in the bore of the corresponding part of the case and in support in combination with an arrangement of said bore, above the chamber receiving the cartridge.
  • the arrangement is a shoulder.
  • the bucket has at its rear part, a sealing skirt and positioning in the bore of the case on the shoulder.
  • the bottom of the cup is convex to support without deformation the gas flow leaving the chamber and to favor its distribution.
  • edges of the rear skirt of the bucket, from the convex bottom, are of decreasing thickness, up to the free end.
  • the front part of the bucket has slots regularly distributed over a circumference to facilitate the opening of said part at the outlet of the box under the pressure of the air.
  • the ammunition comprises a plastic cylindrical case (1), one end (1a) of which is capable of receiving at least one projectile (P), while the other end has a concentric chamber (1b) capable of receiving a cartridge ( 2) reduced size.
  • the chamber (1b) has, over its entire length, a constant and uniform internal diameter corresponding to the diameter of the cartridge (2). This results in an absence of throttling at the outlet of the chamber avoiding the rise in high pressure and makes it possible to reduce the difference between the primary pressure in the cartridge (2) housed in the chamber (1b) and secondary in the free volume. of the case (1) containing the projectile.
  • the cartridge (2) is loaded with pyroxilated powder and receives a primer (3) overloaded with fulminant composition. As a result, the charge of pyroxilated powder is ignited entirely and instantly by a more powerful ignition of the reinforced primer.
  • the projectile (s) are contained in a bucket member (4) mounted to slide freely and centered in the bore (1a) of the corresponding part of the case (1).
  • This cup (4) is supported on a shoulder (1c) formed above the chamber receiving the cartridge (2).
  • the rear part of the bucket (4) has a skirt (4a) for sealing and positioning in the bore (1a) of the case on the shoulder (1c).
  • the bottom (4b) of the cup (4) is convex to support, without deformation, the gas flow leaving the chamber and thus promote its distribution.
  • edges of the rear skirt (4a) of the bucket (4) from the convex bottom (4b), are of decreasing thickness to the free end in order to distribute the pressure of the gas column without depressing the bucket and its content.
  • the front part of the bucket (4) has slots (4c) regularly distributed over a circumference to facilitate the opening of said part at the outlet of the barrel under the pressure of air.
  • the cup (3) is made of plastic.
  • the projectile (s) (P) can be produced from solid bodies of flexible material or else composed of flexible envelopes containing a liquid.
  • the ammunition as described uses a projectile (P) in the form of a spherical bullet made of deformable flexible material.
  • P projectile
  • the outer peripheral edge of the chamber (1b) and the corresponding part of the bore of the case (1), in particular up to the level of the shoulder (1c), are braced by radial fins (1d).
  • the munition according to the invention uses a charge of pyroxilated powder without high pressure.
  • the invention finds a particularly advantageous application for the propulsion of flexible projectiles of large diameter used in particular for self-defense.
  • the ammunition as described and illustrated may advantageously be used in a weapon of the type described in Patent Application No. 2,585,818.
