Abstract

A variable geometry turbine comprising: a turbine wheel mounted for rotation about a turbine axis within a housing. The housing defines an annular inlet surrounding the turbine wheel and defined between first and second inlet sidewalls. A cylindrical sleeve is axially movable across the annular inlet to vary the size of a gas flow path through the inlet. The annular inlet is divided into axially adjacent annular portions by at least one annular baffle which is axially spaced from the first and second inlet sidewalls. Inlet vanes extend axially across at least two of said annular portions defined by the or each baffle so as to divide said annular inlet into at least two axially offset inlet passages. The configuration of the inlet vanes extending into one of the inlet portions differs from the configuration of the inlet vanes extending into another of the inlet portions and the inner diameter of the sleeve is greater than the outer diameter of the inlet passages.
