Oil drain reduction device for spiral compressor has a coolant drive mechanism for high-pressure cooling gas sent through drain aperture of rigid spiral to motor

摘要

The oil drain reduction device includes a coolant guide mechanism for high-pressure cooling gas through a drain aperture (43) of a rigid spiral (40) to a traveler (90) of the drive motor, and an oil separation mechanism passing through the traveler to separate the oil from the gas by a centrifugal force created by the rotation of the traveler.
