TANK HEADROOM VENTING AT GUNNERY

摘要

FIELD: weapons and ammunition.SUBSTANCE: proposed method consists in making the gun breech displaces in first direction at recoil and second direction at rebound. Fixed cylinder is arranged nearby said breech to house movable cylinder rigidly secured via rod with said breech. At gun recoil, breech displaces with piston while rarefaction develops inside the cylinder to make air nearby the breech, saturated with combustion gases is sucked via first one-way valve into cylinder working space to stay therein unless the gun rebound. At rebound, piston displaces in opposite direction to displace air from cylinder via second one-way valve and pipeline out from tank headroom.EFFECT: degreased gas content.1 dwg
