    摘要: An injector (4) for liquid fuel (6a) and a premix burner, in particular for combustion chambers of gas turbines which burner includes an injector (4) of this type, includes a swirl nozzle (14) which is surrounded by a shielding-air passage (11) and has an enlarged cross section of flow in the region of a nozzle-internal swirl generator (12) for the liquid fuel (6a), with this enlarged cross section of flow being reduced again toward an exit opening of the swirl nozzle (14). The injector allows the premix burner to operate with a reduced admission pressure and a high atomization quality.
