The turbocharger which has the bearing housing which possesses the pocket form of the compressor wheel which is improved aerodynamics

摘要

The pocket which is improved aerodynamics (52) the turbocharger unit which it has (10) being, the turbine housing (24) and the axis (20) the turbine wheel which is connected (26) the turbine which it possesses (14) with, the compressor housing (16) and the same axis (20) the compressor wheel which is installed (18) the compressor which it possesses (12) with the turbocharger unit which is included (10). The turbine housing (24) and the compressor housing (16) the axis (20) the intermediate housing which is surrounded (28) is arranged between, this intermediate housing (28) has the pocket of the compressor wheel (50). The intermediate housing (28), the axis (20) the consecutive bearing which is supported (30) is arranged inside. The intermediate housing (28) inside, in addition, the bearing (30) the consecutive fluid passage which supplies the lubricating fluid (33) it is provided. The pocket of the compressor wheel (50) the seal (42) it can use oil in order to prevent the fact that it flows. The pocket of the compressor wheel (50), the compressor wheel (18) the pocket which in order to improve the pressure balance back is improved aerodynamics (52) we have possessed, the intermediate housing (28) the oil inside the compressor housing (16) prevents the fact that it flows.
