Abstract
Disclosed herein is an axially balanced load turbocharger assembly as shown in one form comprises several substantially known components, generally a compressor wheel 22, a turbine wheel 24 and a shaft 26. One form of a housing 28 is also disclosed, which in the specific embodiment disclosed herein comprises several novel components. The apparatus utilizes an oil port in fluid communication with an external oil source, and several oil channels in the housing and in the bearing assembly to direct lubrication oil to all parts which move (rotate) in relation to adjacent components. The apparatus is configured to balance an axially directed load on the shaft so as to minimize damage to the turbocharger, and in particular to the bearing assembly.
