Turbine for and exhaust gas turbocharger

摘要

In a turbine for an exhaust gas turbocharger of an internal combustion engine comprising a turbine housing part, which has at least two spiral channels with respective inlets through which exhaust gas of the internal combustion engine is directed onto a turbine rotor disposed in the turbine housing part, the turbine housing part is disposed in an accommodating chamber, which is formed by a further housing part of the turbine, and from which accommodating chamber exhaust gas of the internal combustion engine can flow through the channel inlets into the spiral channels.

主权项

1. A turbine of an exhaust gas turbocharger (22) of an internal combustion engine (10), comprising at least a first inner housing part (56), which has at least two spiral inlet channels (58) with trumpet-shaped inlet areas (80) which are arranged circumferentially spaced around the first housing part (56), the first housing part (56) with the at least two spiral inlet channels (58) being disposed in a second, outer housing part (72) extending annularly all around the first housing part (56) in spaced relationship therefrom and forming a sealed accommodating chamber (74) in communication with the internal combustion engine to receive and direct an exhaust gas flow of the internal combustion engine (10) through the at least two spiral inlet channels (58) to a turbine wheel (60) disposed within the first housing part (56).
