Abstract

A casing assembly for a turbocharger of an internal combustion engine includes a rotor casing having an intake duct and an exhaust flow passage which is connected to an exhaust flange and constructed for attachment to the rotor casing such as to allow a relative movement between the exhaust flow passage and the rotor casing. In this way, a sliding fit is provided which prevents thermal stress in the system rotor casing and exhaust flow passage. An outer housing surrounds the exhaust flow passage, rotor casing and intake duct.
