Apparatus for minimizing oil leakage during reverse running of a scroll compressor

摘要

A scroll compressor having an apparatus for minimizing oil leakage during reverse running is provided. The compressor includes a suction tube for allowing gas to enter the compressor housing. One oil minimizing apparatus is a check valve disposed at the suction tube having a spring normally biased against the inlet suction tube so as to prevent oil from exiting the suction tube during reverse running of the motor of the compressor. An alternative oil minimizing apparatus is an oil dam extending longitudinally above the suction tube on an inner surface of the compressor housing. The oil dam bends circumferentially with the inner surface for draining oil along the inner surface away from the suction tube.
