Abstract
(EN)
A compressor comprising a rotor, which includes a hub and vanes provided on the outer peripheral surface of the hub, and a casing, which surrounds the rotor so as to face the tips of the vanes with a gap therebetween, wherein if the size of the gap between the casing and the tip of a vane at the front edge position of the vane is t0, then the casing and the tip of the vane have a gap of a size larger than the size t0 in at last a part of the range on the downstream side of the front edge position in the axial direction of the rotor.
(FR)
L'invention concerne un compresseur comprenant un rotor, qui comprend un moyeu et des aubes disposées sur la surface périphérique externe du moyeu, et un boîtier, qui entoure le rotor de façon à faire face aux pointes des aubes avec un espace entre, si la taille de l'espace entre le boîtier et la pointe d'une aube au niveau de la position de bord avant de l'aube est t0, alors le boîtier et la pointe de l'aube ont un espace d'une taille supérieure à la taille t0 dans au moins une partie de la plage sur le côté aval de la position de bord avant dans la direction axiale du rotor.
(JA)
ハブと、ハブの外周面に設けられた翼とを含むロータと、翼の先端と隙間を介して対向するようにロータを囲繞するケーシングと、を備える圧縮機であって、翼の前縁位置における翼の先端とケーシングとの隙間の大きさをt0とすると、翼の先端とケーシングとは、ロータの軸方向における前縁位置よりも下流側の少なくとも一部の範囲において、大きさt0よりも大きな隙間を有する。
