Beschreibung
Zusammenfassung:	Provided is a nozzle tip assembly having a radially inner annular wall and a radially outer annular wall at least partially surrounding the radially inner annular wall and forming therebetween a flow passage for routing air from an upstream end of the nozzle tip assembly to a downstream end of the nozzle tip assembly. Additionally, the nozzle tip assembly has a bleed path for bleeding air from the downstream end of the flow passage into a heat shield that surrounds a fuel delivery device that directs fuel to a plurality of spraywells.
