Abstract (en)

[origin: EP2103793A2] A turbocharger 1 includes a turbine wheel 30, an inner peripheral member 23 provided outside the turbine wheel 30, and an outer peripheral member 13 provided outside the inner peripheral member 23 that can turn relative to the inner peripheral member 23 in the circumferential direction. The inner peripheral member 23 and the outer peripheral member 13 are provided with a plurality of inner guide portions 21 and a plurality of outer guide portions 11, respectively, that define gas passages 22 and 12 between successive guide portions 21, 11. The flow of gas to the turbine wheel 30 through the gas passages may be adjusted by turning one of the outer peripheral member 13 or the inner peripheral member 23 so that the inner guide portions 21 restrict the flow of gas through the gas passages 12 of the outer peripheral member 13.
