Abstract (en)

A fluid machine 110 includes a power recovery mechanism 105 for recovering power from a working fluid, a sub-compressor 102 driven by the recovered power, a shaft 12 coupling the power recovery mechanism 105 and the sub-compressor 102 to each other so that the recovered power is transmitted from the power recovery mechanism 105 to the sub-compressor 102. The power recovery mechanism 105 is provided with a first suction port 26 and a second suction port 27 that open and close, as the first piston 21 rotates, so that the refrigerant flows into the high pressure-side working chamber 23a. The second the suction port 27 is provided at a position facing the first suction port 26 in the axis direction of the shaft 12.
