FLUID MACHINE, RANKINE CIRCUIT, AND SYSTEM FOR UTILIZING WASTE HEAT FROM VEHICLE

摘要

A system for utilizing waste heat from a vehicle has a Rankine circuit, and the Rankine circuit has a fluid machine. An electric power generation unit of the fluid machine has a third rotation body placed coaxial with a first rotation body of a pump unit and with a second rotation body of an expansion unit. Further, the fluid machine has a drive shaft integrally connected to at least the first rotation body among the first, second, and third rotation bodies and also has a power transmission unit connected to the drive shaft and transmitting power from the outside to the drive shaft.
