FIELD: engines and pumps.
SUBSTANCE: invention relates to power engineering. A fuel injector for a turbomachine with a housing (2) including pressurized fuel inlet means, a shut-off valve designed to supply the primary fuel circuit (31, 20) and a metering valve (15) installed downstream of the shut-off valve designed to supply the secondary fuel circuit (17, 21). The injector comprises at least one leakage channel (35) formed, for example, by thread extending from the area (32) located downstream of the shut-off valve and upstream of the metering valve (15) to the area (17) licated downstream of the metering valve (15) and intended to ensure a constant leak in the secondary circuit (17, 21). Turbomachine with at least one injector is also provided.
EFFECT: invention prevents fuel stagnation of in the secondary pipeline at start and low mode operation phases, when the metering valve is not open, and thus precludes fuel coking in the secondary pipeline.
