AN OIL SPOUT (34) IS DRILLED IN THE CRANKCASE (32) OF A SCROLL COMPRESSOR (10) BETWEEN THE OUTER SEAL (44) AND THE COUPLING (46).THE OIL SPOUT (34) INTERSECTS THE OIL RETURN CHAMBER (36) TO REDIRECT A PORTION OF THE OIL EXITING THE OIL RETURN PASSAGE (38) TO THE LOWER SURFACE (48) OF THE ORBITING SCROLL (12) BETWEEN THE OUTER SEAL (44) AND THE COUPLING (46). IT IS PREFERRED THAT THE OIL SPOUT (34) BE SUBSTANTIALLY PERPENDICULAR TO AND SMALLER IN DIAMETER THAN THE OIL RETURN PASSAGE (38). THE OIL SPOUT (34) PROVIDES A CONTINUAL FLOW OF ADDITIONAL LUBRICATION TO THE OUTER SEAL (44) AND THE COUPLING (46), PREVENTING EXCESSIVE WEAR OF THE OUTER SEAL (44) AND IMPROVING OVERALL SEAL RELIABILITY.(FIGURE 2)
