Abstract
An engine turbocharger includes a thermal isolation connection between a rotor and compressor section support and an exhaust section including an exhaust duct attached to the rotor support. The connection includes spring biased wear pads allowing sliding motion at one or more interfaces between the exhaust duct and the rotor support to accommodate relative radial thermal growth. Radial key and slot guides between the exhaust duct and rotor support maintain axial alignment of the connected components during relative radial motion at the connecting interfaces.
