A fluid machine (29A) including: a casing section (56) having a suction port (55) into which a working fluid that becomes a high pressure heated vapor flows; a housing section (54) having a discharge port (53); and a scroll section (51, 52) driven by the working fluid suctioned from the suction port (55). A bypass section (80) including: a bypass passage (81) allowing the suction port (55) to communicate with the discharge port (53); and a valve mechanism (83) opening and closing the bypass passage (81), is supported between the sections (56, 54). When the bypass passage (81) is opened, the working fluid is circulated while bypassing a driving section including the scroll section (51, 52) and a sliding section such as an anti-rotation mechanism (60). Therefore, even when the working fluid in a liquid phase flows, degradation of lubricity in the sliding section can be reduced. |
