Definitions

• the invention relates to the technical sector of ammunition.
• the projectiles used are fragile, so that it is not allowed to use propulsion systems, requiring pyrotechnics operating at high pressure. Such projectiles must therefore be fired under low pressure.
• black powder which makes it possible to have a lively and complete combustion range, under a relatively low pressure.
• the black powder generates significant smoke and residue.
• ammunition comprising a cylindrical case, one end of which receives a projectile, while the other end has a concentric chamber receiving a cartridge of reduced size.
• the chamber has, over its entire length, a constant and uniform internal diameter, corresponding to that of the cartridge, to avoid the rise at high pressure.
• the cartridge is loaded with pyroxilated powder and receives an overheated primer in fulminant composition.
• the object of the invention is to remedy these 5 drawbacks in a simple, safe, effective and rational manner.
• the problem which the invention proposes to solve is to be able to increase the pressure, in order to give speed to the projectile
• the problem which the invention proposes to solve is to increase the pressure at the level of the cartridge and not of the chamber receiving the projectile.
• the propulsion means consisting of a cartridge "blank”, housed in a diffuser, the entire cartridge and of the organ being introduced
• the diffuser member has a coaxial chamber into which the cartridge is introduced
• the chamber of the diffusing member is in communication with oversized lateral orifices arranged at the periphery and the sum of the sections of which exceeds the nominal diameter of said chamber.
• the ammunition can fire any type of projectile made from solid bodies of flexible material, or 35 composed of flexible envelopes containing a liquid.
• the projectile is constituted by a cylindrical body delimiting an internal volume capable of receiving "disperser” means capable of being released under the effect of destruction of said body, combination with a detonator subject to a retarder.
• the detonator is mounted in a cylindrical housing formed coaxially at one of the ends of the body to be ignited by the gases of the cartridge - diffuser assembly.
• the end of the body opposite to that receiving the detonator is closed by a cover.
• the cover has concentric grooves and a non-opening central recess.
• the latter has arrangements formed by grooves formed according to the generatrices of the body.
• the dispersing means consist of CS powder, iron shot, liquid.
• Figure 1 is a sectional view showing before assembly, the main components of the cartridge.
• Figure 2 is a view corresponding to Figure 1 after mounting of the various elements.
• Figure 3 is a cross-sectional view taken along line 3.3 of Figure 2.
• Figure 4 is a longitudinal sectional view before mounting of the main elements of the projectile.
• Figure 5 is a view corresponding to Figure 4 after mounting of the main elements of the projectile.
• Figure 6 is a cross-sectional view taken along line 6.6 of Figure 5.
• Figure 7 is a plan view corresponding to Figure
• Figure 8 is a view showing the projectile in the ammunition.
• the ammunition comprises a cylindrical case (1) of flexible plastic material, not fragile at low temperatures in particular.
• One end of the case (1) is closed and has a concentric chamber (1a) coaxially adapted to receive a means for propelling a projectile (P).
• the projectile (P) is housed in the case (1), after its introduction through the opening (1b).
• the chamber (1a) has, over its entire length, a constant and uniform diameter.
• the propulsion means comprises a blank cartridge (2) housed in a diffuser member (3).
• the assembly of the cartridge (2) and the diffuser (3) is introduced into the coaxial chamber (1a) from the case.
• the diffuser member (3) has an internal recess (3a) into which the blank cartridge (2) of any known and appropriate type is introduced.
• the internal recess (3a) is in communication with lateral orifices (3b) disposed peripherally at the end of the shutter member (3), opposite its open end for the introduction of the cartridge.
• these orifices (3b) are oversized, so that the sum of their section exceeds the nominal diameter of the internal recess (3a).
• the projectile (P) consists of a cylindrical body (4) delimiting an internal volume (4a), intended to receive dispersing means (6), such as CS powder, shot, liquid -
• a detonator subject to a retarder is mounted in a cylindrical housing (4b) formed coaxially at one end of the body (4).
• the detonator - retarder assembly is arranged in coaxial alignment with the cartridge (2) - diffuser (3) assembly, to be ignited by the gases from said cartridge.
• the cylindrical housing (4b) is formed coaxially with a bottom (4c) set back from the corresponding end of the cylindrical body (4).
• the open end of the body (4) is closed by a cover (5). This cover has concentric grooves
• the body (4) has longitudinal grooves (4d) formed according to its generatrices and shaped to constitute incipient fractures, in order to facilitate the bursting of the body under the effect of the action of the detonator.
• the body (4) is introduced manually by the open end (1) of the case (1), being held there by moderate tightening.
• Ammunition and projectile as defined and illustrated apply to any type of large caliber firearm, used in particular as a non-lethal defense weapon.
