摘要： A system includes an injector (102) including a scheduling valve assembly (104) and a nozzle (106) in fluid communication with the scheduling valve assembly. The injector includes two fluid circuits, a primary circuit (110) and a secondary circuit (112), between the inlet of the injector and two respective outlets for staged flow output. A cooling circuit (113) is in fluid communication with the inlet of the injector. The cooling circuit is in thermal communication with the secondary circuit for selectively cooling the secondary circuit at low flow and no flow conditions of the secondary circuit. A separate valve (114, 214) is connected in fluid communication in the cooling circuit for controlling flow through the cooling circuit. The separate valve is configured for active control regardless of pressure at the inlet of the injector. The scheduling valve assembly is configured for passive control of the primary and secondary circuits based on pressure at the inlet of the injector.

摘要： 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. Primary, secondary and auxiliary fuel circuits (117, 119, 118) receive fuel from the scheduling valve, and an electrically-controlled valve (120) is provided in fluid communication with the auxiliary circuit (118), which electrically-controlled valve (120) is adapted and configured to actively control fuel through the auxiliary circuit (118) in response to a control signal.

摘要： A system includes an injector (102) having a scheduling valve assembly and a nozzle in fluid communication with the valve assembly. The scheduling valve assembly is configured for regulation of flow from an inlet of the injector (102) to the nozzle. The injector (102) includes two fluid circuits between the inlet of the injector (102) and two respective outlets of the nozzle for staged flow output from the nozzle. A first one of the two fluid circuits is a primary circuit, and a second one of the two fluid circuits is a secondary circuit. A solenoid valve is connected in fluid communication with the scheduling valve assembly, wherein the solenoid valve is configured to adjust position of a hydromechanical valve spool of the valve assembly.

摘要： 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.
