Abstract

PURPOSE:To improve reliability of scroll type compressor bearing by providing exhaust oil basin on outer side of main bearing housing and to store the exhaust oil remaining after differential pressure feeding as the bearing section coolant. CONSTITUTION:Chamber 1 is maintained at exhaust pressure and intermediate pressure chamber is maintained at intermediate pressure. Lubricant 9 lubricates main bearing 13 etc. and discharged into intermediate pressure chamber 8 when the oil port in shaft 4 is lifted due to the differential pressure between the exhaust pressure and the intermediate pressure. The exhaust oil temperature is lower than the feed oil temperature due to evaporaton of coolant in the lubricant. A recess serving as an oil basin for exhaust oil is provided on outer side of main bearing 13 housing of frame 5 and upper side of main bearing 13 housing are cooled by said exhaust oil.
