Abstract: An assembly is provided for a turbine engine. This turbine engine assembly includes an air swirler structure, an injector nozzle and a nozzle guide. The air swirler structure includes a swirler wall, an inner passage and an air swirler passage. The swirler wall includes a flow guide surface. At least an inner portion of the flow guide surface has a frustoconical geometry. The inner passage extends axially along an axis within the air swirler structure to a swirler outlet. The air swirler passage extends radially into the air swirler structure, longitudinally along the flow guide surface and to the inner passage. The injector nozzle projects axially into the inner passage. The nozzle guide couples the injector nozzle to the air swirler structure. The nozzle guide is axially abutted against the swirler wall.
