PURPOSE: To restrain lubricating oil from flowing into a low-pressure chamber to the utmost as well as to improve the relationship between an oil circulating rate of a refrigerating cycle and a refrigerant flow rate, by installing a low-pressure passage, ranging from a swash plate chamber to the low-pressure chamber, in and around a compressor rotary shaft.
CONSTITUTION: A swash plate chamber 7 and each of low-ressure chambers 18 and 18' are partitioned off by a partition walls 17 and 17'. Inside this swash plate chamber, lubricating oil is separated from a suction refrigerant by rotation of a swash plate 2. This separated lubricating oil is the higher in a distribution rate the nearer to the circumferential side of the inside of the swash plate chamber 7. Therefore, each of low-pressure flow passages 19 and 19' is installed in these partition walls 17 and 17' in and around a compressor rotary shaft 3 being low in this distribution rate.
