    • A flat spray fuel nozzle comprising a generally spherical tip with an elongated fuel discharge slot extending from a spherical chamber. A fuel splitter is adjustably positioned in the chamber, by means of a sleeve-like shim, to divert and reunite fuel at the slot to increase turbulence. An air shroud surrounds the exterior of the tip and has a discharge slot in line with the slot in the tip. A splitter element is positioned in the shroud so that air passing through the shroud is divided into separate streams which impinge on either side of the liquid film adjacent the fuel slot to further increase atomization of the fuel.
    • 平坦的喷射燃料喷嘴,其包括大致球形的尖端,其具有从球形室延伸的细长的燃料排放槽。 燃料分配器通过套筒状垫片可调节地定位在腔室中,以使槽口处的燃料转移和重新团聚以增加湍流。 空气罩围绕尖端的外部,并且具有与尖端中的狭槽一致的排放槽。 分流器元件定位在护罩中,使得通过护罩的空气被分成分开的流,其冲击靠近燃料槽的液膜的任一侧,以进一步增加燃料的雾化。
