  • Oil spout for scroll compressor
    Patent number: 6464480
    Abstract: An oil spout is drilled in the crankcase of a scroll compressor between the outer seal and the coupling. The oil spout intersects the oil return chamber to redirect a portion of the oil exiting the oil return passage to the lower surface of the orbiting scroll between the outer seal and the coupling. It is preferred that the oil spout be substantially perpendicular to and smaller in diameter than the oil return passage. The oil spout provides a continual flow of additional lubrication to the outer seal and the coupling, preventing excessive wear of the outer seal and improving overall seal reliability.
