<p>PROBLEM TO BE SOLVED: To provide a rankine cycle device which uses a volume adjustment mechanism and is able to detect leakage of a working fluid.SOLUTION: A working fluid circuit 11 of a rankine cycle device 10 for a vehicle comprises a volume adjustment mechanism 60 which may supply a refrigerant to a radiator 30. The volume adjustment mechanism 60 includes a storage chamber 63 which is disposed between the downstream side of the radiator 30 and the upstream side of a boiler 50 when viewed in a circulation direction of the working fluid circuit 11 and stores the refrigerant. Further, the volume adjustment mechanism 60 includes: a piston 62 which moves in the storage chamber 63 and varies the volume of the storage chamber 63; and a control part 75 which controls the piston 62 and determines if refrigerant leakage from the working fluid circuit 11 occurs on the basis of a difference between a reference travel distance and an actual travel distance of the piston 62.</p> |
