摘要:
A variable-nozzle turbocharger includes a turbine housing and a center housing, and a generally annular nozzle ring and an array of vanes rotatably mounted to the nozzle ring such that the vanes can be pivoted about their axes for regulating exhaust gas flow to the turbine wheel. The vanes extend between the nozzle ring and an opposite wall formed by an insert in the turbine housing. A vane sealing member is supported on the insert, and has a portion disposed between distal ends of the vanes and the insert. This portion of the vane sealing member is configured to be contacted by the distal ends of the vanes when the vanes are in the closed position, while a clearance exists between the portion of the vane sealing member and the distal ends of the vanes when the vanes are in the open position.
