<P>PROBLEM TO BE SOLVED: To provide a cooling device for an electrically-assisted turbocharger that cools a motor of the electrically-assisted turbocharger. <P>SOLUTION: The cooling device for an electrically-assisted turbocharger 10 includes a motor case 12 and a bearing housing 28 for bearing a turbo shaft 23 of a turbocharger 20 side by side. A motor cooling chamber 15 is formed in the motor case 12 while a bearing cooling chamber 32 is formed in the bearing housing 28. The motor cooling chamber 15 and the bearing cooling chamber 32 are made to communicate with each other. A lubricating-oil inlet 33 is formed in the motor case 12 while a lubricating-oil outlet 34 is formed in the bearing housing 28. Consequently, a cooling lubrication circuit 35 is formed to sequentially supply lubricating oil, supplied from an engine, to the motor cooling chamber 15 and the bearing cooling chamber 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
