FIELD: mechanical engineering; turbomachines. ^ SUBSTANCE: proposed fuel injection system contains high-pressure pump for delivering fuel at high pressure from fuel tank, fuel nozzles arranged in combustion chamber of turbomachine and metering device located between said high-pressure pump and fuel nozzles to control rate of fuel getting into fuel nozzles from high-pressure pump. Metering device contains delivery valve operated in accordance with two delivery levels by metering valve to which fuel is delivered from said high-pressure pump. Electrically controlled shutoff valve is provided additionally to cut off fuel delivery to said fuel nozzles. ^ EFFECT: possibility of limiting heating of fuel and setting optimum dimensions of system components. ^ 5 cl, 2 dwg |
