摘要： A fluid machine according to the present invention has an expansion device for collecting waste heat from an internal combustion engine and converting the collected heat energy into mechanical rotational force, an electric rotating device selectively operating as an electric power generator and as an electric motor, and a pump device for pressurizing refrigerant for Rankine cycle, wherein those components are operatively connected with each other by a single rotating shaft. When starting up Rankine cycle, the electric rotating device is operated as the electric motor, so that the pump device is driven to pressurize and pump out high pressure refrigerant. Once the expansion device starts its operation, the electric rotating device is rotated by the expansion device and therefore the operational mode of the electric rotating device is switched over to the power generating mode. The expansion device will be operated at its maximum efficiency in relation to the heat energy inputted into the Rankine cycle, by controlling the power generation at the electric rotating device.
