Abstract
A fluid machine () includes a closed casing () in which an oil reservoir () for holding oil is formed in a bottom part. Disposed in the closed casing () are: a main compression mechanism (), for compressing a working fluid, to which the oil held the oil reservoir () is supplied; a rotary electric motor () disposed above the oil reservoir () in the closed casing (); a main compressor shaft () for coupling the main compression mechanism () and the rotary electric motor () to each other; a power recovery mechanism () for recovering motive power from the working fluid by performing a suction process for drawing the working fluid and a discharge process for discharging the drawn working fluid; a sub compression mechanism (), which is driven by the power recovery mechanism (), for compressing the working fluid and discharging the working fluid to the main compression mechanism () side; and a power recovery shaft () for coupling the power recovery mechanism () and the sub compression mechanism () to each other.
