<P>PROBLEM TO BE SOLVED: To provide a Rankine circuit using a small-sized fluid machine equipped with a power generation unit which can generate power with high-efficiency, in addition to an expansion unit and a pump unit, and a waste heat utilization system of vehicle. <P>SOLUTION: The waste heat utilization system of vehicle (A) has a Rankine circuit (12), and the Rankine circuit (12) has a fluid machine (14), a heater, and a condenser, in a circulation passage for circulating a heat medium. The power generation unit (26) of the fluid machine (14) has a first rotor of a pump unit (16) and a second rotor of an expansion unit (20) and a third rotor arranged on the same axle. Further, the fluid machine (14) has a drive shaft (72) integrally coupled with at least the first rotor, out of the first rotor, the second rotor and the third rotor, and a power transmission unit (30) coupled with the drive shaft (72), for transmitting power from the outside to drive shaft (72), and the drive shaft (72) is integrally coupled with the first, the second and the third rotors. <P>COPYRIGHT: (C)2012,JPO&INPIT |
