Abstract
A turbine comprises a housing defining a turbine chamber with a turbine wheel supported for rotation about an axis. The housing further defines first and second inlet volutes which each spiral radially inwards and extend from a respective inlet to adjoin the turbine chamber and a volute tongue for each inlet volute. The tongue of the first volute radially separating a downstream portion of the first volute adjacent the chamber from an upstream portion of the first volute adjacent said inlet of the first volute, and the tongue of the second volute radially separating a downstream portion of the second volute adjacent the chamber from an upstream portion of the second volute adjacent said inlet of the second volute. The tongues having a turbine scroll tongue overlap which is substantially zero or positive; and the first volute tongue is angularly spaced about the axis from the second volute tongue.
