Abstract

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.
