Abstract: A nozzle is provided including a nozzle body having an upstream end and a downstream end aligned about a central axis. A discharge portion is positioned adjacent the downstream end. A bore extends inwardly from the downstream end over the length of the discharge portion. An opening is formed in the nozzle body adjacent the discharge portion. The opening is fluidly connected to the bore to provide an interior air flow passage. A main fuel channel extends from the upstream end to the discharge portion. At least one fuel flow branch extends through the discharge portion between the bore and an outer surface of the nozzle body. The fuel flow branch is fluidly coupled to the main fuel conduit to provide a fuel flow passage. The outer air cap is positioned about the outer surface of the discharge portion of the nozzle body to form an exterior air flow passage.

Abstract translation: 提供一种喷嘴，其包括具有上游端和与中心轴对齐的下游端的喷嘴体。 排出部分位于下游端附近。 孔在排出部分的长度上从下游端向内延伸。 在喷嘴体中形成有与喷出部相邻的开口部。 开口流体连接到孔以提供内部空气流动通道。 主燃料通道从上游端延伸到排放部分。 至少一个燃料流分支延伸穿过孔和喷嘴体的外表面之间的排出部分。 燃料流分支流体地联接到主燃料管道以提供燃料流动通道。 外部空气帽围绕喷嘴体的排放部分的外表面定位以形成外部空气流动通道。
