PURPOSE:To make a branched delivery pipe or the like for oil feeding unnecessary and enable to reduce the number of parts as well as the manufacturing cost by a constitution wherein the pressure feeding of the lubricating oil to oil receiving parts is effected by a high-pressure path formed in an oil cover. CONSTITUTION:Compressed refrigerant is changed into discharging gas and flows from a discharging chamber 15 into the high-pressure path 26, formed in the oil cover 24, through discharging paths 17, 18, 19, the energy of the flow of refrigerant is increased by the drooping part 26a of the path 26 and sucks up the lubricating oil from an oil suction port 26e provided at the lowest part of the path 26 when the gas is passing through a rise-up part 26c. The discharged gas and the lubricating oil are mixed and flowed through the high-pressure path 26 and the lubricating oil is reserved in the oil receiving part 25 formed on the end plate 11 of a bearing at the opposite side of a motor while this lubricating oil is sucked and fed from an oil feeding path 27 to respective sliding parts by the sucking effect of the oil suction plate 28 of a rotary shaft 5. Thus, the pressure feeding of the lubricating oil to the oil cover 24, therefore, the branched oil discharging pipe or the like for oil feeding, which are provided in the conventional compressor, are not necessitated and the number of parts as well as the manufacturing cost of the compressor may be reduced. |
