PROBLEM TO BE SOLVED: To suppress a change of a pressure loss in a route for connecting an outlet part of a water jacket and a refrigerant storage part, in a Rankine cycle system in which the refrigerant storage part for temporarily storing a gas-liquid two-phase refrigerant.SOLUTION: Refrigerant passages 14a, 14b are connected to an outlet part 13 of a water jacket 12. The refrigerant passages 14a, 14b are branched at a downstream side immediately below the outlet part 13, and connected to the refrigerant storage part 16. The refrigerant storage part 16 is constituted so as to be capable of temporarily storing a gas-liquid two-phase refrigerant, its upper face 16a is located more in an upper part in a vertical direction from the outlet part 13, and its lower face 16b is located more in a lower part in the vertical direction from the outlet part. The refrigerant storage part 16 is connected to the refrigerant passage 14a at the upper face 16a side, and connected to the refrigerant passage 14b at the lower face 16b side.SELECTED DRAWING: Figure 1 【課題】気液二相の冷媒を一時的に貯留する冷媒貯留部を設けるランキンサイクルシステムにおいて、ウォータジャケットの出口部と冷媒貯留部とを接続する経路での圧力損失の変化を抑制する。【解決手段】ウォータジャケット１２の出口部１３には、冷媒通路１４ａ，１４ｂが接続されている。冷媒通路１４ａ，１４ｂは、出口部１３の直下流において分岐して冷媒貯留部１６に接続されている。冷媒貯留部１６は、気液二相の冷媒を一時的に貯留可能に構成されており、その上面１６ａは出口部１３よりも鉛直方向上方に位置し、その下面１６ｂは当該出口部よりも鉛直方向下方に位置している。また、冷媒貯留部１６は、冷媒通路１４ａと上面１６ａ側で接続し、冷媒通路１４ｂと下面１６ｂ側で接続している。【選択図】図１
