Abstract
A hybrid compressor includes a first compression mechanism, which is driven by a first drive source, a second compression mechanism, which is driven by a second drive source, and a communication path communicating between a suction chamber of the first compression mechanism and a suction chamber of the second compression mechanism. The first compression mechanism may be adapted only to be driven by the first drive source and the second compression mechanism may be adapted only to be driven the second drive source. Therefore, the compression mechanisms are adapted to their respective drive sources.
