Title (EN) VARIABLE NOZZLE UNIT AND VARIABLE DISPLACEMENT SUPERCHARGER
(FR) UNITÉ BUSE VARIABLE ET COMPRESSEUR À SURALIMENTATION À CYLINDRÉE VARIABLE
(JA) 可変ノズルユニット及び可変容量型過給機
Abstract:
(EN) The outer diameter of a second nozzle shaft (65) of each variable nozzle (61) is less than the outer diameter of a first nozzle shaft (63) thereof. The first nozzle shaft (63) is integrally formed on one side surface of the each variable nozzle (61). A portion (61e) is provided to the other side surface of the each variable nozzle (61). The portion (61e) surrounds the second nozzle shaft (65) and is adapted to be capable of being in contact with a second nozzle ring (51). An inner nozzle flange (73) and an outer nozzle flange (75), which are capable of being in contact with a first nozzle ring (43), are integrally formed on the blade surface (61i) and the blade surface (61o) of the each variable nozzle (61) on the side facing the base section of the first nozzle shaft (63).
(FR) Le diamètre externe d'un second arbre (65) de buse de chaque buse (61) variable est inférieur au diamètre externe d'un premier arbre (63) de buse associé. Le premier arbre (63) de buse est formé d'un seul tenant sur une surface latérale de chaque buse (61) variable. Une partie (61e) est prévue sur l'autre surface latérale de chaque buse (61) variable. Ladite partie (61e) entoure le second arbre (65) de buse et est conçue de sorte à pouvoir venir au contact d'un second déflecteur (51). Une bride (73) de buse interne et une bride (75) de buse externe, qui peuvent venir au contact d'un premier déflecteur (43), sont formées d'un seul tenant sur la surface de pale (61i) et sur la surface de pale (61o) de chaque buse (61) variable sur le côté faisant face à la section de base du premier arbre (63) de buse.
(JA)  各可変ノズル(61)の第2ノズル軸(65)の外径寸法は、第1ノズル軸(63)の外径寸法よりも小さい。各可変ノズル(61)の一側面には、第1ノズル軸(63)が一体形成されている。各可変ノズル(61)の他側面には、部位(61e)が設けられる。部位(61e)は、第2ノズル軸(65)の周りを包囲し、第2ノズルリング(51)に接触可能になっている。各可変ノズル(61)の翼面(61i)及び翼面(61o)における第1ノズル軸(63)の基部側に、第1ノズルリング(43)に接触可能なインナノズル鍔(73)及びアウタノズル鍔(75)がそれぞれ一体形成される。
