20 Claims

1. A turbine comprising:

(i) a turbine wheel,

(ii) a turbine housing for defining a chamber for receiving the turbine wheel for rotation of the turbine wheel about an axis, the turbine housing further defining a gas inlet, and an annular inlet passage from the gas inlet to the chamber,

(iii) a ring-shaped shroud defining a plurality of slots and encircling the axis;

(iv) a nozzle ring supporting a plurality of vanes which extend from the nozzle ring parallel to the axis, and project through respective ones of the slots, the shroud and nozzle ring being positioned on opposite sides of the inlet passage, one of the shroud and the nozzle ring being rotatable relative to the turbine housing about the axis by at least 0.1 degree; and

(v) a rotation mechanism for, in use, rotating the one of the shroud and nozzle ring around the axis.
