Abstract
A compression device includes a plurality of compressors in a shell. Each compressor includes a rolling piston that rotates within a cylinder to compress refrigerant. At least one valve allows refrigerant to be simultaneously or successively compressed by the compressors. A first pipe transfers refrigerant into one of the compressors, and a second pipe transfers refrigerant compressed in one of the compressors to another one of the compressors when the refrigerant is successively compressed by the compression mechanisms. The first and second pipes are coupled to the cylinder of one of the compressors.
