ABSTRACT:
An oil return device for a refrigeration system which is placed in the suction line between the evaporator and the compressor to insure that the lubricant oil in the gases is returned to the compressor to prevent damage to the compressor. The device includes an inner tube within an outer tube each of which are connected to a tee fitting so that fluid flows downwardly between the two tubes and upwardly in the inner tube only. A venturi effect is produced at the end of the inner tube which speeds the fluid sufficiently to carry the oil along with the refrigerant.
