    • A nozzle (100) for air-assisted atomizing of a liquid fuel comprises a fuel feed passage (110) and an air feed passage (114) and a swirling chamber (118) from which fuel and air may be passed to an exit orifice (126) for emerging a cone shaped spray. An air bypass passage (122) is provided for leading a fraction of the air flow in the air feed passage (114) past the swirling chamber (118) and to an air exit (124) arranged such with respect to the exit orifice (126) that, during operation of the nozzle, air emerging through the air exit (124) reduces depositing of residues of fuel on a downstream surface (130, 132, 136) of the nozzle element (108). Grooves or other flow-guiding elements may confer swirling or rotation of air in or downstream of the air feed passage (114) and/or the air bypass passage (122).
    • 用于液体燃料的空气辅助雾化的喷嘴(100)包括燃料供给通道(110)和空气供给通道(114)和旋转室(118),燃料和空气可从该喷嘴(118)通向出口( 126)用于出现锥形喷雾。 空气旁路通道(122)用于引导空气供给通道(114)中的空气流的一部分经过旋转室(118),并且相对于出口孔(126)布置的空气出口(124) ),在喷嘴的操作期间,通过空气出口(124)排出的空气减少了在喷嘴元件(108)的下游表面(130,132,136)上沉积燃料残留物。 沟槽或其它流动引导元件可以使空气在空气供给通道(114)和/或空气旁路通道(122)的下游或者空气旁路通道(122)的下游旋转或旋转。
