FIELD: combustion chambers of aircraft gas-turbine engines. SUBSTANCE: device has main injectors connected with fuel pump, starting injectors connected in parallel with fuel pump through constant fuel pressure differential electromagnetic valve which is connected with automatic start control unit and high-pressure compressor. Innovation of invention consists in installation of electromagnetic check valve between constant fuel pressure differential electromagnetic valve, starting injectors and high-pressure compressor. EFFECT: stable reliable start and operation of engine due to automatic anti-carbon purging of starting fuel pipe lines and starting injectors at all modes of operation with pure air bled from high-pressure compressor and discharged to flame tube and then to gas duct. |
