Patent ID: 7610843

Claim:
An individual firearm with improved recock device comprising: a casing ( 12 ), a barrel ( 13 ), a breech bolt ( 14 ), a breech bolt slide ( 15 ), said barrel ( 13 ) being housed in casing ( 12 ) and comprising at least one gas bleeding port ( 32 ), which communicates with a gas intake cylinder ( 19 ) which in turn houses a piston gas intake assembly ( 20 ), said piston gas intake assembly ( 20 ) being connected to operating rods ( 31 ) which arc connected to said breech bolt slide ( 15 ), which is connected to the breech bolt ( 14 ) at an end of said barrel ( 13 ), said piston gas intake assembly ( 20 ) comprising inertial spring ( 27 ) which is compressible by the recoil of the casing and breech bolt ( 14 ) by the firing of a cartridge, said inertial spring ( 27 ) being positioned between said breech bolt slide ( 15 ) and said gas intake cylinder ( 19 ), said gas intake cylinder ( 19 ) having a piston body ( 21 ) which is capable of moving independently of the piston gas intake cylinder ( 20 ) by force resulting from firing a cartridge, said piston gas intake assembly ( 20 ) further comprising an elastic scaling band ( 22 ) which is adapted to close said at least one gas bleeding port ( 32 ) when sufficient force is applied to inertial spring ( 27 ) by the firing of said cartridge, said elastic sealing band ( 22 ) being fitted on piston body ( 21 ), said inertial spring being a helical spring which is arranged so that in response to the firing of a cartridge, said piston body ( 21 ) and said inertial helical spring cause said operating rods ( 31 ) to recock said firearm.
