LUBRICATION OF VOLUMETRICALLY OPERATING EXPANSION MACHINES

摘要

The method involves delivering a vaporous working medium that contains a lubricant from an evaporator (20) in such manner that the lubricant exists in the working medium in form of oil droplets. A portion of lubricant is deposited from the vaporous working medium supplied by the evaporator. The working medium is delivered, which is depleted by depositing a portion of the lubricant to the expansion machine (30). An independent claim is also included for a device for use with an expansion machine.
