ABSTRACT:
An apparatus for recovering a compressible refrigeration fluid from a refrigeration system and delivering the recovered fluid to a receiver includes a discriminator tank for discriminating between influent liquid phase fluid and gas phase fluid. Liquid phase fluid is directed to the receiver. Gas phase fluid is condensed and directed to the receiver. The apparatus further includes a safety tank for preventing overfilling of the receiver and a lightweight compressor particularly adapted to refrigerant recovery. The lightweight compressor includes self lubricating bidirectional seals and renders the recovery apparatus easily transportable to allow convenient field servicing of refrigeration systems.
