Abstract: PROBLEM TO BE SOLVED: To provide an electrically driven compressor capable of improving reliability of a bearing part in inclusion of ferrous contaminant.SOLUTION: An electrically driven compressor houses a compressor mechanism part 4 which compresses and ejects refrigerant and an electric motor 5 which drives the compressor mechanism part in a sealed container 1, and supplies lubricating oil reserved in a reservoir 16 in the sealed container to a primary bearing 22 and an eccentric bearing 24 of the compressor mechanism part. A contaminant capture part 27a is provided to cover an oil supply port at the upstream of the oil supply port of a driving shaft. The contaminant capture part 27a is made from a porous magnetic body. Accordingly, the capture part can reliably capture a ferrous contaminant, so contaminant ingress into a bearing part is prevented, thereby improving reliability of the bearing part.

Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of a start failure and reliability upon rebooting by oil supplied from a high-pressure region to a back-pressure chamber by a pressure difference even after a stop of a compressor, and further supplied from the back-pressure chamber to a compression chamber, and thereby to prevent a lubricant in a liquid storage part from being reduced and the compression chamber from being filled with the lubricant.SOLUTION: The compressor includes: back-pressure chamber oil-supply passages 25a, 25b, and 25c which supply the lubricants 7 from the high-pressure regions 21a and 21b to the back-pressure chamber 22; and compression-chamber oil-supply passages 26a and 26b which supply the lubricants 7 from the back-pressure chamber 22 to the compression chamber. A phase at which the back-pressure chamber oil-supply passages communicates with the back-pressure chamber 22 from the high-pressure region and a phase at which the compression-chamber oil-supply passages communicates with the compression chamber from the back pressure chamber 22 are shifted. As a result, the back-pressure chamber oil-supply passages and compression-chamber oil-supply passages do not communicate with each other simultaneously, thus preventing the lubricants 7 from being communicative and supplied from the high-pressure region to the back-pressure chamber 22 after the stop of a compressor.
