UNIFIED PRIMER FOR HAND GRENADES Russian patent published in 2013 - IPC F42C14/02 F42B8/26 

FIELD: weapons and ammunition.

SUBSTANCE: proposed primer comprises fire circuit elements including capsule, igniter, retarder and detonator or petard arranged in soft plastic case with branch pipe, and safety-punching mechanism with spring-loaded striker, trigger, pin, cotter pin and ring arranged in cartridge. Primer cartridge is made from relatively stiff and elastic plastic, for example, armamide. It has two symmetric stepped lengthwise cutouts abruptly converging over open end face, on the side of open end face to height of case branch pipe. Cutouts divide cartridge bottom into semi-cylinders press-fitted on case branch pie with two wedge-like external ledges mating cartridge cutouts in cartridge to be plugged therein and latched. Note here that two radial through holes are made in case branch pipe wall, in plane perpendicular to its ledges. Coaxial cylindrical collar is made above point of safety-punching mechanism to enter inside branch pipe to stop during pining down igniter cap. Gas pressure is created via holes in branch pipe to act on semi-cylinders of cartridge to open it while, via striker, to remove safety-punching mechanism from case branch pipe.

EFFECT: decreased sizes, higher reliability and safety.
