Abstract
【解決手段】本ノズルアセンブリは、ノズル本体(114)とオリフィスプレート(118)とを含む。オリフィスプレート(118)は、ノズル本体(114)の内部に着脱自在に配置することができる。
【選択図】 図3
Description
一方、カラー116をノズル本体114と一体形に形成した場合には、カラー116とノズル本体114との接合部142は、ノズル本体114の周りで比較的一様である。例えば、接合部142は、約±0.005インチの許容差の範囲内で変動するようにすることができる。従って、一次燃料ノズルアセンブリ106は、その断面積におけるより小さい変動を有することができ、かつ破損することなく比較的高い応力に耐えることができる。
