Beschreibung
Zusammenfassung:	This two-stage scroll compressor comprises: a sealed container that constitutes an outer shell; a drive mechanism unit that is disposed inside the sealed container and serves as a drive source; two compression mechanism units that are respectively disposed above and below the drive mechanism unit, each having a compression chamber formed by combining a fixed scroll that is fixed inside the sealed container and an orbiting scroll that is driven by the drive mechanism unit; a crankshaft that transmits the driving power of the drive mechanism unit to the two orbiting scrolls; and a balancer that is provided to the crankshaft and cancels out an unbalance caused by the two orbiting scrolls. The two orbiting scrolls are provided eccentrically in the same direction with respect to the center axis of the crankshaft.
