Abstract

The invention relates to a thermodynamic circuit process device comprising a working medium having a lubricant additive; an expansion machine (5) for converting enthalpy in the working medium into mechanical energy; a multi-stage pressure-increasing apparatus (1) for the step-by-step pressurization of the working medium; a means (4) for branching a part of the working medium between two stages of the multi-stage pressure-increasing apparatus (1); and a means (4) for feeding the branched off part of the working medium to one or a plurality of bearing points of the expansion machine. The invention further relates to a corresponding method for lubricating an expansion machine in a thermodynamic circuit process device.
