| description | A liquid fuel injector includes a cylindrical primary fuel injecting body having a central axis; an annular shroud concentrically placed radially outside; and an annular secondary fuel injecting body placed concentrically with the primary fuel injecting body and the shroud between the primary fuel injecting body and the shroud. A plurality of inner swirlers placed at equal intervals in a circumferential direction are provided in an annular inner air passage formed between the primary fuel injecting body and the secondary fuel injecting body, and a plurality of outer swirlers placed at equal intervals in the circumferential direction are provided in an annular outer air passage formed between the secondary fuel injecting body and the shroud. The primary fuel injecting body is formed as a pressure spray-type injector, and the secondary fuel injecting body and the inner and outer air passages cooperatively constitute an airblast-type injector. |
