FIELD: engines and pumps.
SUBSTANCE: proposed device incorporates localisation and combustion product cooling chamber. Note that the said chamber end section communicates via an intermediate jointing section with a gas duct to make an open surface intended for reduction of excess pressure in the aforesaid jointing section and gas duct by allowing combustion products to escape and cool them by ejecting air from atmosphere in compliance with the following ratio d3/d2=d2/d1 to 1.1 to 2 where dl is diameter of localization and cooling chamber, d2 is diameter of intermediate jointing section, d3 is gas duct diameter. The depth of the intermediate jointing section penetration into gas duct is determined from the ratio L=0.05 to 0.01d where L is the said depth, d is diameter of the section that extends inside.
EFFECT: higher process and ecological safety.
