ル圧縮機の軸受冷却構造。 A rotating shaft that is pivotally supported by the case body and has a rotating shaft forming a crankshaft at its tip, a boss into which the crankshaft is inserted via a bearing, and a spiral wrap formed on the opposite side. a scroll, a fixed scroll having a spiral wrap that meshes with the wrap of the orbiting scroll to form an air compression chamber and fixed to the case body side; and a compression chamber side in which the orbiting scroll and the fixed scroll are housed. and a partition plate fixed to the case body to define an introduction chamber into which cooling water is introduced. In a bearing cooling structure for a water circulation scroll compressor formed to cool the bearing, compression chamber, etc. by introducing cooling water into the introduction chamber, a nozzle protruding into the introduction chamber is fixed on the partition plate. The protrusion length of the nozzle is at least higher than the protrusion length of the boss portion from the partition plate surface, and a passage communicating between the inside of the nozzle and the compression chamber side is formed through the partition plate. Features a bearing cooling structure for a water circulation scroll compressor.
