Abstract
A variable geometry turbine comprises a turbine wheel () supported in a housing () for rotation about a turbine axis. An annular inlet passage () is defined between first and second radial inlet surfaces, one of said first and second inlet surfaces being defined by a moveable wall member (). A substantially annular array of vanes () is provided which extend across the inlet passageway (); each vane () being fixed to said first inlet surface. Each vane () has first and second major vane surfaces () having a chordal length extending between a radially outer leading vane edge () and a radially inner trailing vane edge (), the first major vane surface () facing generally away from the axis and the second major vane surface () facing generally towards the axis. A rib () extends across at least a substantial portion of the chordal length of at least one of the first and second major vane surfaces () of one or more vanes () of the array.
