Abstract:
A turbocharger, with a turbine that includes a turbine housing, turbine inflow housing, a rotor, and a compressor, which has a compressor housing and a rotor coupled to the turbine rotor via a shaft. A bearing housing is arranged between and coupled to the turbine and the compressor housings. The turbine inflow housing has a radially inner, outer and middle walls. The inner wall delimits an exhaust gas flow duct, and a cooling channel between the outer and middle walls. The bearing housing, extends, seen in the axial direction as far as into the region of the inner wall of the turbine inflow housing. A cooling water channel in the bearing housing surrounds the inner wall of the turbine inflow housing in the axial region and the bearing housing extends as far as into the region of the radially inner wall of the turbine inflow housing, radially on the outside.
