Abstract

The invention relates to a variable-vane assembly for variable intake to a turbine wheel of a turbocharger, comprising: - a nozzle plate (1) encircling an axis and having a nozzle surface (11) on which a plurality of vanes (4) is circumferentially arranged around the axis, each vane (4) being movable such as to vary the cross-sectional intake area to the turbine wheel (2); - a turbine housing (3), housing the turbine wheel (2), wherein the turbine housing (3) comprises a vane cover (31) having a cover surface (32) that faces the vanes (4) and circumferentially surrounds the turbine wheel (2) such that the vanes (4) are sandwiched between the nozzle surface (11) and the cover surface (32); and - a flange (33) connected to the vane cover (31) and encircling the nozzle plate (1), characterized by that the nozzle plate (1) has a nozzle tapered surface (14) around its outer perimeter, wherein the nozzle tapered surface (14) is tapered along a direction of the axis, and the flange (33) has a flange tapered surface (34) around its inner perimeter, matching the nozzle tapered surface (14), wherein the nozzle tapered surface (14) is resting on the flange tapered surface (34) such that a gap is maintained between the nozzle surface (11) and the cover surface (32).
