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.

Apparatus for recovering refrigerant with offset cam

A fill control valve for a pressure vessel, e.g. a refrigerant container wherein said valve is disposed within said container and includes a pair of fluid passageways wherein a one-way check valve is disposed in one of said passageways for permitting flow of liquid refrigerant from inside said vessel to a point outside of said vessel and the other of said passageways permits the filling of said vessel with liquid and gas refrigerant. Said other passageway being provided with a normally closed spring-loaded poppet valve and float activated lever means for closing said valve at a pre-determined refrigerant level in said vessel.
