摘要： 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. The turbine further comprises a cylindrical sleeve that 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 at least two axially offset inlet passages. The inner diameter of the sleeve is greater than the inner diameter of the inlet passages.

摘要： A variable geometry turbine comprising an annular inlet surrounding a turbine wheel mounted for rotation about a turbine axis within a turbine chamber defined by a housing. The chamber has an annular inlet defined between inboard and outboard inlet side walls and surrounding the turbine wheel. The annular inlet includes: a first pair of first and second circumferentially spaced inlet passages; and a second pair of third and fourth circumferencially spaced inlet passages. The second pair of inlet passages is axially displaced from the first pair of inlet passages and a cylindrical sleeve is supported within the housing for reciprocal motion in an axial direction to vary the size of the annular inlet. The sleeve is movable between at least a first position in which each of the first pair of inlet passages is at least partially open to gas flow, and the second pair of inlet passages are fully open to gas flow, and a second position in which the first pair of inlet passages are fully blocked to the gas flow and each of the second pair or inlet passages is at least partial!/ blocked to gas flow.

摘要： 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.
