FIELD: engines and pumps.
SUBSTANCE: invention relates to power engineering. A fuel injector for a turbomachine consists of a housing comprising a primary fuel circuit and a secondary fuel circuit, fed by a metering valve (15). The leakage channel (36, 37, 38) extends from the area (32) fluidly connected to the primary circuit, to the area (17), fluidly connected with the secondary circuit. The leakage channel (36, 37, 38) is open in the closed state of the metering valve (15) and is closed by metering valve (15) movement. Turbomachine with at least one fuel injector is also provided.
EFFECT: invention eliminates fuel coking in the secondary pipeline in startup and low mode phases without degrading of turbomachine performance in medium or high modes.
