Title (EN) SUPERCHARGER
(FR) COMPRESSEUR DE SURALIMENTATION
(JA) 過給機
Abstract:
(EN)  This supercharger is provided with: a centrifugal compressor having an impeller linked to a rotating shaft; a bearing housing for accommodating a bearing for rotatably supporting the rotating shaft, the bearing housing facing the rear surface of the impeller; a head tank provided to the bearing housing and configured so as to store lubricating oil supplied to the bearing; a labyrinth seal provided between the rear surface of the impeller and the bearing housing, the labyrinth seal including an annular labyrinth seal plate and a labyrinth fin integrated with the labyrinth seal plate; and a heat-transfer-promoting means configured so as to promote heat transfer between the lubricating oil stored in the head tank and the labyrinth seal plate.
(FR)  Compresseur de suralimentation pourvu : d'un compresseur centrifuge comportant une roue reliée à un arbre rotatif; d'un logement de palier destiné à recevoir un palier pour supporter en rotation l'arbre rotatif, le logement de palier faisant face à la surface arrière de la roue; d'un réservoir de tête situé sur le logement de palier et conçu de manière à stocker de l'huile de lubrification apportée au palier; d'un joint à labyrinthe disposé entre la surface arrière de la roue et le logement de palier, le joint à labyrinthe comprenant une plaque de joint à labyrinthe annulaire et une ailette à labyrinthe faisant corps avec la plaque de joint à labyrinthe; et d'un moyen favorisant le transfert de chaleur conçu de manière à favoriser le transfert de chaleur entre l'huile de lubrification stockée dans le réservoir de tête et la plaque de joint à labyrinthe.
(JA)  回転軸に連結された羽根車を有する遠心圧縮機と、前記回転軸を回転自在に支持する軸受を収容し、且つ、前記羽根車の背面に対向する軸受ハウジングと、前記軸受ハウジングに設けられて前記軸受に供給される潤滑油を貯留するように構成されたヘッドタンクと、前記羽根車の背面と前記軸受ハウジングとの間に設けられ、環状のラビリンスシール板及び該ラビリンスシール板と一体のラビリンスフィンを含むラビリンスシールと、前記ヘッドタンクに貯留された潤滑油と前記ラビリンスシール板との間の熱伝達を促進するように構成された熱伝達促進手段とを備える。
