A system for a thermodynamic cyclic process arrangement with an internal combustion engine and a system, method for the lubrication an expansion device in a system for a thermodynamic cyclic process and the motor vehicle

摘要

The invention relates to a system (5) for a thermodynamic cyclic process with an evaporator (7) and a – along a system cycle (9), as seen in the direction of flow of a working medium, downstream of the evaporator (7) arranged expansion device (13), wherein between the evaporator (7) and the expansion device (13) a separation device (11) is arranged which is set up for the separation of liquid lubricant of gaseous working medium, wherein a lubricating means path (19) of the separation device (11) to the expansion device (13) is provided, in such a way that the expansion device (13) in the separation device (11) can be supplied with lubricant for lubricating separated.
