Abstract
A variable geometry turbine comprises a turbine wheel and a primary inlet passage of variable axial width. The turbine has a secondary inlet passage provides a flow path for a working fluid which circumnavigates at least part of the primary inlet passage. A seal element and one or more apertures are cooperable to selectively allow or prevent fluid flow through the secondary inlet passage. The ratio of the minimum cross-sectional area of the flow path through the primary inlet passage to that of the secondary inlet passage is between 1.3 and 1.7.
