Claim Text:
1. An airblast injector for atomizing a liquid, comprising: a swirler with a longitudinal axis; and a nozzle body defining an air passage therethrough along the longitudinal axis with a diverging outlet, wherein the swirler is operatively associated with the diverging outlet of the nozzle body, wherein the nozzle body includes a liquid circuit having an outlet radially outward of and axially overlapping the diverging outlet of the air passage for airblast atomization of liquid sprayed from the outlet of the liquid circuit assisted by swirling air from the swirler, wherein the swirler further comprises: wherein the swirl vanes are angled to impart swirl around the longitudinal axis on air flowing over the diverging upstream surface, wherein the diverging upstream surface of the swirler body and the diverging outlet of the air passage define a conical flow passage, and wherein the plurality of swirl vanes are substantially disposed within the conical flow passage between the diverging surface of the swirler body and the diverging outlet of the nozzle body, wherein swirl vane end surfaces of the plurality of swirl vanes are affixed to a surface of the diverging outlet defined by the nozzle body.
