A vapor engine includes an expander, a lubricant storage zone, and a combination regenerative heat exchanger and lubricant separator. The combination device receives a mixture of lubricant and vaporized working fluid from the expander; the vaporized working fluid passes through the combination device to a condenser and the lubricant is separated from the working fluid and directed back to the lubricant storage zone. The lubricant storage zone is vented to a locus in the engine at a lower pressure than the pressure in the combination device to insure that the lubricant storage zone pressure will not exceed the pressure in the combination device.
