CARTRIDGE FOR SMALL ARMS Russian patent published in 2016 - IPC F42B5/02 F42C19/10 

FIELD: machine building.

SUBSTANCE: invention relates to special engineering in production of small arms cartridges. In design of cartridge for small arms for improving its manufacturability and reducing its cost providing stability of geometrical dimensions of the socket for a capsule and types of rounds, in which caps-igniters with mass of priming composition of impact action from 22 mg to 30 mg are used, while varying the shape of press-fitting of priming composition of impact action in Cap primer, so that even if mass and volume of priming composition of impact action varies within ±15 % of average mass at permanent geometric dimensions of capsule seat, metal cap and a three-lobed anvil, in any case it simultaneously contact both with ignition compound impact action and with special circular ledge at the bottom of a capsule seat.

EFFECT: technical result consists in ensuring reliability and trip sensitivity of self-contained operation of the CAP primer, as well as in decrease of time for its actuation.
