FIELD: engine engineering. SUBSTANCE: when the combustion chamber of the gas-turbine engine is in operation, the pressure in housing 1 of the combustion chamber increases. As a result, step-shaped spring-loaded slide valve 11 lifts and entrains valve 3. Air-operated cylinder 14 is connected to housing 1. Double-arm delaying mechanisms 12 and 13 of the outlet valve are broken apart to the other side. Double-position valve 9 lifts, overlaps pipe line 6 for supplying fuel, and opens valve 8 for discharging fuel. The combustion products enters outlet nozzle 7. The ambient air cools rod 5 of valve 3 through passageway 18. When the issuing of the combustion products stops, valves 2 and 3 are closed, and valve 9 opens pipe line 6 and closes passageway 8. EFFECT: enhanced reliability. 1 dwg
