Abstract
A turbocharger includes a variable-nozzle cartridge having a nozzle ring that supports an array of variable vanes in the turbine nozzle. A heat shroud and spring assembly is disposed in a space bounded between the turbine wheel, the nozzle ring, and the center bearing housing of the turbocharger. The heat shroud and spring assembly includes discretely formed heat shroud and spring components configured as annular non-planar disk-shaped parts. The heat shroud and spring are in contact with each other at their radially inner and radially outer peripheral regions, but are spaced apart between those peripheral regions, thereby creating a sealed-off dead space between them. The dead space can significantly reduce the maximum temperature of the spring, relative to arrangements having a single shroud or having dual shrouds with no dead space between them.
