Multi-stage compressor and multi-stage compression process

摘要

A plurality of parallel compression paths connect a suction chamber to a discharge chamber. A plurality of compression chambers are formed in each compression path. Fluid is drawn to the suction chamber and is then compressed in the compression chambers in each compression path in a plurality of compression stages. Afterward, the fluid is discharged from the discharge chamber. A first compression chamber that corresponds to a predetermined compression stage in each compression path is connected to a second compression chamber that corresponds to a subsequent compression stage in the compression path through a communication chamber. The communication chamber is provided separately for each compression path.
