FIELD: engines and pumps.
SUBSTANCE: fuel injector for gas turbine engine, for example, aircraft turbojet or turboprop engine incorporates high-pressure pump to supply fuel consumption regulator with its outlet communicated via fuel feed control valve with fuel injector supply line. Note here that said valve is communicated with inlet and outlet of pump to generate two threshold surplus fuel pressures. One pressure serves to start and restart gas turbine engine while another pressure is used to operate said engine beginning from idling, and to control variable-geometry equipment.
EFFECT: higher efficiency.
