FIELD: weapons and ammunition.
SUBSTANCE: method of removing powder gases from breech piece of tank armament involves the following: when armament electric trigger is pressed, the signal is transmitted by electric wires to timing relay and to actuating element. The first check valve is opened, air is bled off from air system bottle by pipeline, impeller is rotated thus generating rarefaction of air in breech zone. Air gassy with powder gases is forced to casing, and through impeller and the second check valve it is removed from armament breech piece by pipeline.
EFFECT: reducing level of powder gases pollution of fighting chamber.
