An assembly is provided for a gas turbine engine (20). This assembly includes an air swirler structure (66), an injector nozzle (114) and a nozzle guide (70). The air swirler structure (66) includes an inner bore (108) and an air swirler passage (102). The inner bore (108) extends axially along an axis (72) through the air swirler structure (66). The air swirler passage (102) extends radially into the air swirler structure (66) to the inner bore (108). The injector nozzle (114) projects axially into the inner bore (108). The nozzle guide (70) couples the injector nozzle (114) to the air swirler structure (66). The nozzle guide (70) includes a guide foot (146) and an air purge passage (144) radially outboard of the guide foot (146). The guide foot (146) is configured to radially engage the injector nozzle (114). The air purge passage (144) extends across the nozzle guide (70) and axially to the inner bore (108).
