Abstract
An airtight compressor includes a compression mechanism disposed inside an airtight container in a position below a gas retention space. An oil supply passage supplies oil from an oil reservoir both to the gas retention space () and to a sliding portion of the compression mechanism in a compression space. The oil supply passage communicates the gas retention space with a second space located on an opposite side of the piston from the intake chamber. A second channel is a channel that is different from the oil supply passage. The second channel enables a gas medium to flow from the gas retention space to the second space. Preferably, passage resistance when the gas medium flows through the second channel is less than when the gas medium flows through the oil supply passage.
