Abstract

Turbo-compresseur à gaz d'échappement comprenant un compresseur centrifuge composé d'un corps et d'un rotor, une turbine composée d'un corps et d'un rotor, et un corps de paliers supportant l'arbre commun entre le corps de compresseur et le corps de turbine. La turbine (corps 1; rotor 14) est calorifugée par rapport au corps de paliers 2. De préférence, l'une au moins des parois de délimitation voisines 19, 20 du corps de turbine 1 et du corps de paliers 2 est refroidie par une fente 21 entre lesdites parois. Application : à la suralimentation de moteurs à combustion interne.
