Abstract

L'INVENTION CONCERNE UN TURBOCHARGEUR DANS LEQUEL UN ARBRE COMMUN A LA TURBINE ET AU VENTILATEUR EST SUPPORTE ROTATIF PAR DES PALIERS COTE TURBINE ET COTE VENTILATEUR, DISPOSES DANS UNE ENVELOPPE, ET IL EST LUBRIFIE PAR UNE HUILE DE LUBRIFICATION. SELON L'INVENTION, UNE CHAMBRE 24 DE REFROIDISSEMENT S'ETEND CIRCONFERENTIELLEMENT A L'ARBRE COMMUN 9 ET ADJACENTE AU PALIER 7 COTE TURBINE ET A UNE PAROI DE SEPARATION 4 ENTRE L'ENVELOPPE 1 DES PALIERS ET L'ENVELOPPE 2 DE LA TURBINE, AU MOINS UN PASSAGE D'HUILE TRAVERSANT L'ENVELOPPE DES PALIERS POUR L'ECOULEMENT DE L'HUILE DE LUBRIFICATION DU PALIER 8 COTE VENTILATEUR ET DE SA PROXIMITE VERS LA CHAMBRE DE REFROIDISSEMENT, UNE CHAMBRE DE PURGE 26 AVEC UNE SORTIE D'HUILE 27 ETANT PREVUE POUR L'EVACUATION DE L'HUILE DE LUBRIFICATION DE LA CHAMBRE 24. L'INVENTION S'APPLIQUE NOTAMMENT AUX MOTEURS A ESSENCE OU DIESEL.THE INVENTION CONCERNS A TURBOCHARGER IN WHICH A SHAFT COMMON TO THE TURBINE AND THE FAN IS ROTATING SUPPORTED BY TURBINE SIDE AND FAN SIDE BEARINGS, ARRANGED IN A SHELL, AND IT IS LUBRICATED BY LUBRICATING OIL. ACCORDING TO THE INVENTION, A COOLING CHAMBER 24 EXTENDS CIRCUMFERENTIALLY TO THE COMMON SHAFT 9 AND ADJACENT TO THE BEARING 7 ON THE TURBINE SIDE AND TO A SEPARATION WALL 4 BETWEEN THE ENVELOPE 1 OF THE BEARINGS AND THE ENVELOPE 2 OF THE TURBINE, AT LEAST ONE PASSAGE OF OIL THROUGH THE BEARING ENCLOSURE FOR THE FLOW OF LUBRICATING OIL FROM THE BEARING 8 FAN SIDE AND ITS PROXIMITY TO THE COOLING CHAMBER, A DRAIN CHAMBER 26 WITH AN OIL OUTLET 27 PROVIDED FOR THE EVACUATION OF LUBRICATING OIL FROM CHAMBER 24. THE INVENTION APPLIES IN PARTICULAR TO GASOLINE OR DIESEL ENGINES.
