Abstract

A variable geometry turbine has an annular inlet 9 to a turbine wheel 5, the inlet includes first and second axially spaced passages which extend from an outer diameter to an inner diameter. A generally cylindrical sleeve 30 is moveable for varying the size of the annular inlet. The sleeve is movable in a first direction from a first position to an opening position of the second inlet passage, during which movement the second inlet passage is closed. When the sleeve is in the opening position, the cross-sectional area of an opening to the first inlet passage defined between a free, first end of the sleeve and the first inlet passage sidewall is substantially equal to the minimum cross-sectional area of the first inlet passage. Movement of the sleeve in the first direction beyond the opening position of the second inlet passage serves to initiate opening of the second inlet passage.
