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 turbine wheel is of the radial-inflow axial-outflow type and secondary inlet passage has an outlet configured to direct working fluid to exit the secondary inlet passage in a direction which has an axial component in the opposite direction to the direction of axial outflow of the turbine wheel.
