PROPORTIONAL RESTRICTION OF A SECONDARY CIRCUIT OF A FUEL INJECTOR

A fuel injector for a turbine engine includes a fuel scheduling valve configured for regulation of fuel flow from a fuel inlet (115), in response to fuel pressure received at the fuel inlet (115). Primary, secondary and auxiliary fuel circuits receive fuel from the scheduling valve, and an electrica...

Beschreibung
Zusammenfassung:	A fuel injector for a turbine engine includes a fuel scheduling valve configured for regulation of fuel flow from a fuel inlet (115), in response to fuel pressure received at the fuel inlet (115). Primary, secondary and auxiliary fuel circuits receive fuel from the scheduling valve, and an electrically-controlled valve is provided in fluid communication with the auxiliary circuit, which electrically-controlled valve is adapted and configured to actively control fuel through the auxiliary circuit in response to a control signal. The auxiliary fuel circuit joins with the secondary fuel circuit for delivery to a fuel nozzle.
