WIPO Patent Application WO/2016/063704

Kind Code:

A1

Abstract:

　Provided are a hermetically sealed compressor which, despite the use of a sintered compact as a fastener part for fastening a compressor mechanism part to a hermetically sealed container, obviates the need for after-processing, affords good shaping accuracy, and moreover minimizes processing costs; as well as a refrigeration cycle device equipped with the same. In this hermetically sealed compressor, which has a compressor mechanism part housed within a hermetically sealed container, the hermetically sealed container and the compressor mechanism part being fastened to one another by a fastener part, the compressor mechanism part is gap-fitted within the hermetically sealed container, a flange part of the compressor mechanism part in relation to the hermetically sealed container is constituted by a sintered compact, and an outer peripheral portion of the flange part comprising the sintered compact is provided with a latch groove that extends from one end surface to the other end surface side of the flange part. A protruding part intruding into the latch groove is provided in a section of the hermetically sealed container facing the latch groove, and the fastening part for fastening the compressor mechanism part and the hermetically sealed container together is constituted by the latch groove of the compressor mechanism part and the protruding part of the hermetically sealed container.
