PROBLEM TO BE SOLVED: To provide a composite hydraulic machine that can improve a mountability of the composite hydraulic machine by integrating an inverter with a housing, while efficiently cooling the inverter. SOLUTION: A composite hydraulic machine 40 includes, inside a housing 41, an expander unit 85 for outputting mechanical energy by an expansion of refrigerant, a compressor unit 60 for compressing the refrigerant, a motor generator 50 for functioning as an electric generator or an electric motor, and an electromagnetic clutch 52 for switching a drive shaft 51 of the motor generator 50 and a compressor shaft K of the compressor unit 60 into a connected state or a disconnected state. An inverter 90 is integrated with the housing 41 so as to be thermally coupled to a motor housing 42, a pump housing 43, and a front housing 44 of the housing 41. The inverter 90 is cooled, via each of the housings 42, 43 and 44, by the refrigerant which is discharged from the expander unit 85 and sucked into the compressor unit 60.
