摘要：<p>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; and a cylindrical sleeve axially movable across the annular inlet to vary the size of a gas flow path through the inlet; wherein the annular inlet is divided into a first annular inlet portion and a second annular inlet portion axially offset from the first inlet portion, inlet vanes extending axially into each of the first and second inlet portions, the inlet vanes defining axially adjacent inlet passages; wherein the configuration of the inlet vanes extending into the first inlet portion differs from the configuration of the inlet vanes extending into the second inlet portion in that the vanes extending into the first inlet portion are circumferentially offset from the vanes extending into the second inlet portion.</p>
