Abstract
The inside of a sealed container () of a horizontal scroll compressor is partitioned by a partition plate () into a space in which a compressor mechanism section and an electric motor are contained and into a discharge space () in which a discharge pipe () and an oil supply pump () are contained. An upper communication path () and a path guide member () are provided in the upper part of the partition plate, and a refrigerant gas passes through the upper communication path (). The path guide member is located below the discharge pipe (), is extended to a position near a side surface of the sealed container, and has a path area greater than the path area of the discharge pipe. The construction causes the refrigerant gas to collide with the side surface of the sealed container, promoting separation of oil, and even if the oil is re-dispersed by a gas flow, the construction reduces flow directly leading to the discharge pipe.
