Co-rotating scroll compressor

A co-rotating scroll compressor comprising:

• a housing;
• a driving mechanism;
• a driving scroll;
• a driven scroll;
• and a driven mechanism,
• the housing having a scroll chamber in which the driving scroll and the driven scroll are accommodated, a storage chamber that separates a refrigerant drawn from an outside into gas and liquid and stores liquid refrigerant, and a partition wall that separates the storage chamber from the scroll chamber,
• the driving scroll being configured to be driven to rotate around a driving axis by the driving mechanism,
• the driven scroll being eccentric to the driving scroll, and configured to be driven to rotate around a driven axis by the driving scroll and the driven mechanism,
• a supporting portion protruding from the partition wall into the scroll chamber with the driving axis at a center,
• the driving scroll being supported by a bearing disposed between the driving scroll and the supporting portion so as to be driven to rotate around the driving axis,
• a scroll compression part being formed of the driving scroll and the driven scroll,
• an oil storage portion in which lubricating oil is stored being provided in the scroll chamber, and
• a lubricating oil supply passage in communication with the oil storage portion, through which the lubricating oil is supplied to the scroll compression part or the bearing, wherein
• the lubricating oil supply passage has a lubricating oil cooling portion that cools the lubricating oil in the lubricating oil supply passage with the refrigerant in the storage chamber.
