The present invention provides a method for lubricating an expansion machine, which method comprises: supplying of an operating medium which contains a lubricant by a vaporizer; separating of at least part of the lubricant from the operating medium which contains a lubricant and is supplied by the vaporizer; and supplying of the operating medium, which is depleted by the separation of the at least one part of the lubricant from the lubricant, to the expansion machine. Furthermore, a device is provided having a vaporizer which is configured for vaporizing an operating medium which contains a lubricant and for supplying it to an expansion machine, and having a lubricant separating device which is configured for separating at least one part of the lubricant from the operating medium which contains the lubricant and is supplied by the vaporizer to the expansion machine.

Thermodynamic machine and method for the operation thereof
The invention relates to a thermodynamic machine having a circulation system in which a working fluid, in particular a low-boiling working fluid, circulates alternately in a gaseous and a liquid phase, a heat exchanger, an expansion machine, a condenser, and a fluid pump. The invention also relates to a method for operating the thermodynamic machine. According to certain embodiments of the invention, in the flow line of the fluid pump, a partial pressure increasing the system pressure is applied to the liquid working fluid by adding a non-condensing auxiliary gas. Compact ORC machines can be implemented, preventing cavitation in the liquid working fluid.
