1. a fuel nozzle (222) comprising:

  • Swirler assembly (302), it has outer cover (402) and hub (406);

    A plurality of blades that extend between described outer cover and described hub, each described blade comprise on the pressure side wall (412) and relative suction sidewall (410), and described suction sidewall is located and axially spaced trailing edge place is connected to described pressure sidewall in leading edge (414);

    At least one suction side fuel injection orifice (500) that contiguous described leading edge forms, described at least one suction side fuel injection orifice extends to described suction sidewall from first fuel supply channel (424), and be oriented with respect to described suction sidewall and become a fuel injection angle (504), described at least one suction side fuel injection orifice is configured to discharge fuel from described suction sidewall;

    At least one is fuel injection orifice (502) on the pressure side, its at least one from first and second fuel supply channels (426) extends to described pressure sidewall, described at least one on the pressure side fuel injection orifice be arranged essentially parallel to described trailing edge, and be configured to basically to discharge fuel along described trailing edge tangential direction.
