Abstract (en)

It is an object to provide a compressor which can supply a relatively large amount of oil while preventing shortage of the oil. The compressor includes a sealed container (40), a rotary shaft (2) supported in the sealed container (40), a compression mechanism (20) that compresses a refrigerant upon rotation of the rotary shaft (2), an oil supply conduit (2a) that is formed inside the rotary shaft (2), and allows the oil supplied to the compression mechanism (20) to flow through it, an oil reservoir (11 provided inside the sealed container (40) in its lower portion, oil retaining means (17) having a part disposed in the oil reservoir (11) and the remaining part disposed in the gas space above the oil reservoir (11), and containing a large number of voids to retain the oil, and an oil supply pipe (10) having its one port connected to the oil supply conduit (2a), and its other port disposed in the oil reservoir (11).
