PROBLEM TO BE SOLVED: To feed compressed gas to a multi-system line of different pressure by a single compressor. SOLUTION: A compressor 1 is formed into a structure capable of compressing two-system gas of different compression ratio by the single compressor. In a high pressure system compression part which is one compression system, impellers 17a, 19a are provided in both ends of a low/high pressure stage pinion shaft 10, 11, sucked gas is compressed by the impellers 17a, 19. In a low pressure system compression part of the other compression system, an impeller 21a is provided in an end part of a pinion shaft 12, by rotating the impeller 21a, sucked gas is compressed by compression ratio different from the above compression system. |
