Abstract (en)
[origin: WO2011042695A2] According to a first aspect of the present invention there is provided a variable geometry turbine comprising: a turbine wheel mounted for rotation about a turbine axis within a housing, the housing defining an annular inlet surrounding the turbine wheel and defined between first and second inlet sidewalls, the annular inlet being divided into at least two axially offset inlet portions; a cylindrical sleeve axially movable across the annular inlet to vary the size of a gas flow path through the inlet; wherein an axial extent of a leading end of the sleeve varies in magnitude around a circumference of the sleeve. The variation in the axial extent defines a plurality of recesses and/or protrusions located around the circumference of the leading end of the sleeve. The sleeve, or the axial extent thereof, is free of vanes.
