Abstract

The invention relates to a personal weapon, intended for semi-automatic and automatic firing of caseless ammunitions, provided with an electronic fire controller with biometric identification of the person firing. The weapon has a sealing device for the chamber based on using segments or corollas with variation of bore size mechanically or with gas pressure. A delay in opening the barrel/breech unit may be introduced using spigots driven by propellant gases. A device for sequencing compartments in tandem of the magazine uses the volume reduction of ammunition to double the power of the firearm. A removable locker permits the integral locking of breech unit, trigger, magazine and dismantling bolt for an absolute weapon safety. A telescopic extension device for the barrel increases the power of the ammunition and a gas bleed in the chamber permits the stabilisation of the firing.

 on the heads of spring pumps ( 47 ), placed out of star around the axis of the piston, said pumps sitting on a conical stage ( 45  bis) of the central sleeve whose displacement, under the action of propellant gases, causes a radial pressure on said spring pumps which compress and cause the uniform diameter increase of the segment by plating it against the wall of the piston cylinder ( 62 ) thus ensuring the gas sealing.    on balls ( 54 ) or spigots disposed all around the sleeve ( 44 ) in the segment housing groove, so as to be simultaneously in contact with the internal face of said segment and a conical stage ( 45  bis) of the sleeve whose displacement causes the radial extension involving the uniform diameter increase of the ring seal by plating it against the wall of the piston cylinder ( 62 ) thus ensuring the gas sealing.    around an expansible disc ( 46 ) sitting on a stage of the central sleeve whose displacement, under the action of propellant gases, causes the compression of said disc involving its uniform diameter increase and that the ring seal ( 41 ) by plating it against the wall of the piston cylinder housing ( 62 ) thus ensuring the gas sealing.    around a circular groove ( 42  bis), concentric with the seat groove ( 42 ), intended to uniformly distribute the action of propellant gases on the internal face of the segment ( 41 ,  41  bis,  41  ter,  41  quart & quint,  41  sept) causing its uniform diameter increase by plating it against the cylinder wall ( 62 ) of the piston chamber ensuring thus the gas sealing.    in front of radial lights or crenels ( 40  ter) arranged on the periphery of the cartridge basin so as to uniformly distribute the action of propellant gases on the internal face of the segment, couple of segments ( 41 ,  41  bis,  41  ter,  41  quart & quint,  41  sept) or corollas ( 41  sept, nove & eleven) causing a uniform diameter increase and a contact with the cylinder wall ( 62 ) of piston housing ensuring thus the gas sealing.    such that, in the case of two segments ( 41  quart,  41  quint) with a profile preferentially but not exclusively out of square or L shaped, concentric and indexed at 180°, the short branch (drawing  7 / 27 ,  FIG. 6 / 12  to  6 / 14 ) of their section penetrates in a circumferential groove dug at the bottom and on level of the lower edge of their housing groove ( 42 ) forming a shoulder ( 42  quint) so that when the piston recoils, under the friction effects of the external segment ( 41  quint) on the chamber wall, the short branch of the L section of the internal segment ( 41  quarter) abuts against the shoulder ( 42  quint) forming thus a sealing and preventing any gas leakage circulating behind the segments.
