| 摘要 |
<p>The invention relates to an energy recovery unit comprising a turbine (10) and implementing the Rankine cycle in which an organic working fluid is expanded as it passes through the turbine (10). The turbine includes bearings (11, 12) lubricated by oil collected in an oil sump (C), said oil for lubricating the bearings (11, 12) being at least partially driven by the working fluid after the expansion thereof through the turbine (10). In addition, the unit includes separation means (20) for separating the oil contained in the working fluid, positioned upstream of the inlet of the turbine (10) and arranged to return the oil to the oil sump (C). The unit is characterized in that the turbine (10) is a scroll turbine (10) and in that the separation means (20) are arranged to allow an amount of oil, within a predetermined range of values, to pass into the working fluid entering the turbine inlet (10) in order to lubricate the mobile scroll.</p> |
