Compressor

A compressor comprising:

• a casing defining (i) a suction port configured to introduce refrigerant into the compressor, (ii) a discharge port configured to discharge the refrigerant, and (iii) an oil storage space configured to store oil;
• a driver coupled to an inner circumferential surface of the casing;
• a rotating shaft coupled to the driver and including:
• an oil feeder configured to collect the oil stored in the oil storage space, and
• an oil supply passage connected to the oil feeder and extending in a direction away from the oil storage space, the oil supply passage being configured to allow the oil collected by the oil feeder to flows;
• a compressing portion including:
• an orbiting scroll configured to receive the oil from the oil supply passage, the orbiting scroll being coupled to the rotating shaft and configured to orbit based on the rotating shaft rotating,
• a fixed scroll engaging the orbiting scroll and configured to receive the refrigerant from the suction port to compress and discharge the refrigerant, wherein the oil feeder extends through the fixed scroll, and
• a main frame seated at the fixed scroll and configured to accommodate the orbiting scroll, wherein the rotating shaft extends through the main frame;
• a first passage disposed at the main frame and being in communication with the oil supply passage to thereby receive the oil from the oil supply passage;
• a second passage extending from the first passage toward an outside of the casing and configured to enable the oil to flow the outside of the casing;
• a third passage extending from the second passage and disposed at the outside of the casing;
• and
• a main passage extending from the third passage and extending through the fixed scroll or the main frame.
