摘要： A nozzle (40) includes an inlet at an upstream end of the nozzle, a discharge outlet at a downstream end of the nozzle, and a fluid delivery passage extending between the inlet and the discharge outlet. Exterior (210) and interior (208) walls of the nozzle (40) have downstream tip ends that are relatively longitudinally movable at one or more interfaces. An internal insulating gap (206b) is interposed between the interior and exterior walls to insulate fuel from ambient temperature conditions exterior to the nozzle. One or more flexible (222) seal structures internal to the nozzle isolate a portion of the insulating gap (206b) from any ambient fluid entering into the gap through the one or more interfaces while providing relative movement between interior and exterior walls of the nozzle.

摘要： A nozzle (16) for a fuel injector can include an outer air swirler (24) having an inner surface with the outer air swirler (24) having a groove (34) on the inner surface and a prefilmer (28) located concentrically within the outer air swirler (24) with the prefilmer (28) having at least one detent finger (36) to engage the groove (34) on the inner surface of the outer air swirler (24). The nozzle (16) can also include a fuel swirler (30) located concentrically within the prefilmer (28) and configured to convey fuel to a forward end of the nozzle (16) with the fuel swirler (30) having at least one tab (38) extending axially at an aft end, and an inner air swirler (32) having a cylindrical forward end (40) located concentrically within the fuel swirler (30) and an aft support (42) extending radially outward to contact the outer air swirler (24) with the cylindrical forward end (40) contacting at least one tab (38) of the fuel swirler (30) to hold the fuel swirler (30) in place.
