IMPROVEMENT OF A TURBOGENERATOR SYSTEM, PARTICULARLY AUTOMOTIVE, BY INTEGRATING AN OIL SEPARATOR

Abstract

The invention relates to an energy conversion device (1000) with a turbogenerator (100) comprising a turbomachine (110) whose compressor (4), receiving an upstream gas flow driven by a turbine (6) via a shaft (20) lubricated by a lubrication circuit (200), sends, via a recuperator (1), a compressed gas flow to a combustion chamber (3) supplying the turbine (6). The lubrication circuit (200) includes a lubricant reservoir (8) whose contents are conveyed by a pump (7) to a front bearing (21) supporting said shaft (20) at the compressor (4) and to a rear bearing (22) supporting said shaft (20) at the turbine (6), before its return by a return pump (9) to the reservoir (8). The turbogenerator (100) includes an oil separator (2) between the compressor (4) and the combustion chamber (3). The invention also relates to a motor vehicle comprising this device. (1000).
