Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a premix pilot nozzle and a fuel nozzle assembly.SOLUTION: The premix pilot nozzle includes a nozzle body having a forward wall 130 located at a distance in an axial direction from an aft wall 132, and an outer band 134 that extends axially between the forward wall 130 and the aft wall 132. An air tube 138 extends coaxially within the nozzle body and defines a cooling air plenum 142 within the nozzle body. A fuel tube 154 extends coaxially within the nozzle body and circumferentially surrounds the air tube 138 so as to define a fuel inlet 172 plenum therebetween. A fuel distribution plenum 164 is defined within the nozzle body and is in fluid communication with the fuel inlet 172 plenum. The nozzle body further includes a plurality of premix tubes 168.SELECTED DRAWING: Figure 5 【課題】予混合パイロットノズルおよび燃料ノズルアセンブリを提供する。【解決手段】予混合パイロットノズルは、後壁１３２から軸方向に間隔を置いて配置された前壁１３０を有するノズル本体および前壁１３０と後壁１３２との間で軸方向に延在する外側バンド１３４を含む。空気管１３８は、ノズル本体内に同軸に延在し、ノズル本体内に冷却空気プレナム１４２を画定する。燃料管１５４は、ノズル本体内に同軸に延在し、空気管１３８を円周方向に囲んで、その間に燃料入口１７２プレナムを画定する。燃料分配プレナム１６４は、ノズル本体内に画定され、燃料入口１７２プレナムと流体連通する。ノズル本体は、複数の予混合管１６８をさらに含む。【選択図】図５
