Abstract
A fluid machine has a compressor device for compressing refrigerant of a refrigerating cycle for an automotive vehicle, an electric rotating device operating as an electric motor for generating a rotational driving force to drive the compressor device or operating as an electric power generator, an expansion device for collecting waste heat from an engine and generating a rotational driving force to drive the electric rotating device and/or the compressor device, and a switching device for connecting or disconnecting the compressor device with or from the expansion device. In the fluid machine, the waste heat from the engine can be always collected by the expansion device, irrespectively whether or not the compressor device is operating for an air conditioning operation.
