Abstract
A device is added to a refrigeration system to protect the compressor from liquid slugging. The device traps liquid slugs in the suction pipe and then injects the trapped slugs into the discharge pipe. Any refrigerant within the injected slug is quickly vaporized and travels with the discharge gas to again accomplish useful cooling. Any oil within the injected slug travels with the discharge gas to the oil separator, where it is extracted from the discharge gas and then properly returned to the compressor to again provide lubrication.
