Abstract

Le turbocompresseur comporte un arbre d'entraînement (3) ; un rouet (7.1) relié à une première partie d'extrémité axiale de l'arbre d'entraînement (3) ; un moteur électrique relié à une deuxième partie d'extrémité axiale de l'arbre d'entraînement (3) ; un agencement de palier axial configuré pour limiter un mouvement axial de l'arbre d'entraînement (3) pendant le fonctionnement, l'agencement de palier axial comportant une plaque de palier axial (18) ayant une forme de bague annulaire et étant tournée vers le rouet (7.1) ; un distributeur d'entrée (33) définissant au moins partiellement un trajet de flux de fluide frigorigène d'entrée (P) ; et un agencement de refroidissement de palier axial comportant des ouvertures de dérivation (40) formées dans le distributeur d'entrée (33) et un trajet de flux de fluide frigorigène de dérivation (43) défini par le distributeur d'entrée (33) et la plaque de palier axial (18), les ouvertures de dérivation (40) étant configurées pour dériver une partie d'un flux de fluide frigorigène d'entrée, s'écoulant dans le trajet de flux de fluide frigorigène d'entrée (P), dans le trajet de flux de fluide frigorigène de dérivation (43) de manière à refroidir au moins partiellement la plaque de palier axial (18).The turbocharger has a drive shaft (3); an impeller (7.1) connected to a first axial end portion of the drive shaft (3); an electric motor connected to a second axial end portion of the drive shaft (3); an axial bearing arrangement configured to limit axial movement of the drive shaft (3) during operation, the axial bearing arrangement including an axial bearing plate (18) having an annular ring shape and facing towards the spinning wheel (7.1); an inlet distributor (33) at least partially defining an inlet refrigerant flow path (P); and an axial bearing cooling arrangement having bypass openings (40) formed in the inlet distributor (33) and a bypass refrigerant flow path (43) defined by the inlet distributor (33) and the axial bearing plate (18), the bypass openings (40) being configured to bypass part of an inlet refrigerant flow, flowing in the inlet refrigerant flow path (P) , in the bypass refrigerant flow path (43) so as to at least partially cool the axial bearing plate (18).
