PROBLEM TO BE SOLVED: To provide a sealed rotary compressor with saved electric power, reduced vibration, low noises and high reliability, preventing the insufficient lubrication of sliding portions due to the shortage of oil quantity by properly distributing lubricating oil to the sliding portions consistently when the level of the lubricating oil is abruptly lowered by operating conditions. SOLUTION: A reciprocating vane portion has oil supply pumping operation. The lubricating oil residing on the bottom of a sealed container is pumped up into an oil supply pump chamber and returned from an oil outlet passage communicating the oil supply pump chamber with the sealed container into the sealed container.
