Title
(EN) COMPRESSOR FOR SUPERCHARGER OF INTERNAL COMBUSTION ENGINE
(FR) COMPRESSEUR POUR COMPRESSEUR D'ALIMENTATION DE MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の過給機のコンプレッサ
Abstract
(EN) A compressor for the supercharger of an internal combustion engine is provided with a shroud (4), an impeller (10), a vane-less diffuser (20), and a scroll (30). In a longitudinal cross-section including the rotation axis (CL) of the impeller (10), the hub-side wall surface (22) of the vane-less diffuser (20) is tilted relative to the direction (L1) perpendicular to the rotation axis (CL) of the impeller (10) toward the side opposite a shroud-side wall surface (24). As a result of this configuration, deposits accumulating on the hub-side wall surface (22) of the vane-less diffuser (20) are reduced.
(FR) L'invention concerne un compresseur pour le compresseur d'alimentation d'un moteur à combustion interne comportant une enveloppe (4), une roue (10), un diffuseur lisse (20), et une volute (30). Dans une coupe transversale longitudinale comprenant l'axe de rotation (CL) de la roue (10), la surface de paroi côté moyeu (22) du diffuseur lisse (20) est inclinée par rapport à la direction (L1) perpendiculaire à l'axe de rotation (CL) de la roue (10) vers le côté opposé à une surface de paroi côté enveloppe (24). En conséquence de cette configuration, il y a réduction des dépôts s'accumulant sur la surface de paroi côté moyeu (22) du diffuseur lisse (20).
(JA)  シュラウド(4)と、インペラ(10)と、ベーンレスディフューザ(20)と、スクロール(30)とを備える内燃機関の過給機のコンプレッサにおいて、ベーンレスディフューザ(20)のハブ側壁面(22)は、インペラ(10)の回転軸線(CL)を含む縦断面において、インペラ(10)の回転軸線(CL)に垂直な方向(L1)に対しシュラウド側壁面(24)とは反対の側に傾いて形成される。このような構成によれば、ベーンレスディフューザ(20)のハブ側壁面(22)に堆積するデポジットは少なくなる。
