Title: TURBINE FOR AN EXHAUST TURBOCHARGER
Abstract:
The invention relates to a turbine for an exhaust turbocharger, comprising: a turbine housing (12), through which exhaust gas of an internal combustion engine can flow and which has at least two volutes (14, 16), which are fluidically separated from each other at least in some regions and through which the exhaust gas can flow, and at least one flow-over opening (18), by means of which the volutes (14, 16) can be fluidically connected to each other; a turbine wheel, which is rotatably accommodated in the turbine housing (12) and which can be driven by the exhaust gas; at least one bypass channel, by means of which the turbine wheel can be bypassed at least by part of the exhaust gas; and a valve element (10), which can be rotated in relation to the turbine housing (12) about an axis of rotation (22) and which has a valve body (24), by means of which a first amount of the exhaust gas flowing through the bypass channel and a second amount of the exhaust gas flowing through the flow-over opening (18) can be set, wherein the valve body (24) is designed as a ring segment, the center point of which lies on the axis of rotation (22).
