Abstract
An exhaust gas-driven turbocharger ( ) exhibits an adjustable radial turbine ( ) which powers a compressor ( ) by way of a common shaft ( ), whereby a turbine housing ( ) designed with a multiplicity of scrolls surround the turbine wheel ( ) and exhibits at least two afflux ports ( ) annularly encompassing the turbine wheel ( ), whose outlets ( ) at least partly surround the wheel approach ( ) of the turbine wheel ( ) and which are at an axial distance from one another. An annular, axially displaceable coupler ( ) is provided for opening and closing the outlet ( ) of at least one afflux port ( ), so that the boost pressure of the turbine can be influenced thereby.
