Zusammenfassung:	A turbocharger (1) includes a compressor section and a cast turbine section. The turbine section includes a turbine wheel (4), and a turbine housing (11) that defines a gas inlet (13), a gas outlet (10), a volute (9) disposed between the gas inlet (13) and the gas outlet (10). The turbine housing (11) also includes vanes (20) that protrude integrally from, and have a fixed orientation relative to, an inner surface of the turbine housing (11). The turbine wheel (4) is disposed in the turbine housing (11) between the volute (9) and the gas outlet (10), and the vanes (20) are disposed in the turbine housing (11) between the turbine wheel (4) and the volute (9). A method of casting the turbine housing (11) and the vanes (20) together as a single piece is described. L'invention porte sur un turbocompresseur (1), qui comprend une section compresseur et une section turbine moulée. La section turbine comprend une roue de turbine (4), et un boîtier de turbine (11) qui définit une entrée de gaz (13), une sortie de gaz (10), et une volute (9) disposée entre l'entrée de gaz (13) et la sortie de gaz (10). Le boîtier de turbine (11) comprend également des aubes (20) qui font saillie d'un seul tenant à partir d'une surface interne du boîtier de turbine (11), et qui ont une orientation fixe par rapport à cette dernière. La roue de turbine (4) est disposée dans le boîtier de turbine (11) entre la volute (9) et la sortie de gaz (10), et les aubes (20) sont disposées dans le boîtier de turbine (11) entre la roue de turbine (4) et la volute (9). L'invention porte également sur un procédé de moulage du boîtier de turbine (11) et des aubes (20) ensemble sous la forme d'une pièce unique.
