Compressor having oil separator

A compressor comprising:

• a discharge chamber that is formed in a housing;
• a discharge passage that is formed in the housing and discharges refrigerant from which oil has been separated by the oil separation member to an external refrigerant circuit;
• and
• an oil passage that is formed in the housing and introduces oil separated by the oil separation member into an oil reservoir chamber, wherein
• an oil separation member that is a separate member from the housing and separates oil from refrigerant discharged from the discharge chamber;
• the oil separation member has a partition member that partitions between the discharge chamber and the discharge passage,
• a circular ring portion is provided in a manner extending toward the discharge passage in the partition member,
• a separation space is formed inside of the circular ring portion,
• at least one introduction hole that communicates the discharge chamber and the discharge passage with each other is formed in the circular ring portion,
• the at least one introduction hole extends in a tangential direction to the separation space formed in the circular ring portion,
• a flange portion extending radially outside the circular ring portion from an outer peripheral edge portion of the circular ring portion, wherein the flange portion has an annular shape and is circular, and wherein the flange portion is arranged on a side of the circular ring portion opposite to the partition member;
• a guide groove formed in an end surface of the flange portion, wherein the guide groove is continuous with the at least one introduction hole;
• and
• a groove formed in an end surface of the partition member facing the discharge passage, wherein the groove is continuous with the at least one introduction hole,
• wherein a refrigerant, which has been discharged to the discharge chamber, is introduced into the separation space via the at least one introduction hole and then circles in the separation space.
