PURPOSE:To enable a compressor to reduce its lubricating oil brought out to the outside of the compressor, by providing a partitioning plate between the lowermost part of an electric motor and the lubricating oil accumulated in the bottom part of an enclosed vessel. CONSTITUTION:Communication paths 25, 26, through which a delivery chamber 15 communicates with an electric motor chamber 18, are provided in the peripheral part of a block 9 and a fixed scroll 1, and in the bottom part of the communication paths 25, 26, a long duct 27, which introduces delivered refrigerant gas to the bottom part of an electric motor 8, is mounted into an enclosed vessel 10. And a partitioning plate 28 is mounted between the lowermost part of the electric motor 8 and lubricating oil accumulated in the bottom part of the enclosed vessel 10. Here the lubricating oil, which is allowed to flow together with the refrigerant gas guided to the bottom part of the electric motor 8 by the duct 27, is separated from the refrigerant gas when the oil collides against the partitioning plate 28, and the lubricating oil, which drops down by its dead weight being again accumulated to the bottom part of the enclosed vessel 10, is supplied for lubrication of each part. Accordingly, a compressor, which can reduce the lubricating oil brought out to the outside of the compressor, enables a refrigerant system to be prevented from decreasing its ability.
