Реферат: A variable flow-restricting turbine assembly for a turbocharger is disclosed. The assembly comprises a housing, a turbine mounted for rotation in the housing, and a variable flow-restrictor. The variable flow-restrictor comprises a first series of angularly-distributed flow-restrictor portions distributed around the turbine wheel and located in an exhaust flow path to the wheel, and a second series of angularly- distributed flow-restrictor portions distributed around the first series and located in the exhaust path. At least one of the first and second series is rotatable in the housing to vary the relative angular positions of the first and second series. The restrictor portions are arranged such that the first portions align with the second portions at each of a plurality of relative angular positions to open flow channels between the portions and such that they misalign between those positions to close the flow channels.
