摘要：
A fuel injector 100 for a gas turbine engine includes a monolithic nozzle body 102 that defines within its interior one or more fuel circuits 110. Each fuel circuit includes an inlet 112, an outlet orifice 114, a main passage 118 fluidly coupling the inlet with the outlet orifice, and a branch passage 120 connected to the main passage. The branch passage 120 connects to the main passage downstream of the inlet and upstream of the outlet orifice to form an effective metering flow area that is smaller than the flow area of the outlet orifice.
