<p>A variable-vane assembly includes a generally annular nozzle ring (38) and an array of vanes (34) rotatably mounted to the nozzle ring and connected to a rotatable actuator ring (42), and an insert having a tubular portion structured and arranged to be sealingly received into a bore of a turbine housing and having a nozzle portion (56) extending generally radially out from one end of the tubular portion 54), the nozzle portion 56) being axially spaced from the nozzle ring (38) such that the vanes extend between the nozzle ring and the nozzle portion. A ring-shaped wire cage (60) is disposed radially outwardly of the vanes and has one axial end rigidly affixed to the nozzle ring (38) and an opposite axial end rigidly affixed to the nozzle portion (56) so as to fix a spacing between the nozzle ring and the nozzle portion in an axial direction of the variable-vane assembly.</p> |
