Abstract: A system includes an injector including a scheduling valve assembly and a nozzle in fluid communication with the scheduling valve assembly. The injector includes two fluid circuits, a primary circuit and a secondary circuit, between the inlet of the injector and two respective outlets for staged flow output. A cooling circuit 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 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.
