SYSTEM FOR AUTOMATIC CONTROL OF FUEL DELIVERY INTO COMBUSTION CHAMBER OF GAS TURBINE ENGINE

摘要

FIELD: mechanical engineering; gas turbine engines. SUBSTANCE: channel with fitted-in jet connecting command space of shutoff valve with control space of servopiston is introduced additionally into position control unit of shutoff valve. Fuel delivery cut-in and cut-off electromagnets are coupled with normally closed valves connecting servopistons control space with drain and inlet main lines, accordingly. EFFECT: simplified design owing to dispensing with complex control devices, improved reliability of fuel delivery control, eliminated draining of working medium at working positions of shutoff valve. 1 dwg
