Abstract
A compressor has auxiliary and main oil reservoir chambers that retain lubricant oil that is separated from refrigerant in an oil separation chamber. A part of the auxiliary oil reservoir chamber is defined by a peripheral wall of the oil separation chamber. An introducing passage for introducing lubricant oil in the oil separation chamber to the auxiliary oil reservoir chamber is formed in the peripheral wall. The inlet of the introducing passage opens to the oil separation chamber on the inner surface of the peripheral wall. The outlet of the introducing passage opens to the auxiliary oil reservoir chamber. The main oil reservoir chamber is located below the auxiliary oil reservoir chamber in the direction of gravity. A drain port for draining lubricant oil in the auxiliary oil reservoir chamber to the main oil reservoir chamber is formed in a bottom wall of the auxiliary oil reservoir chamber.
