Abstract
To provide a scroll-type fluid machine in which the influence on power recovery efficiency of a clearance in an expansion section is reduced. A scroll-type fluid machine (100) includes: a scroll unit (20) in which a fixed scroll (3) and an orbiting scroll (4) are disposed and an expansion section (1) and a compression section (2) are formed; and a support part (30) that supports the orbiting scroll (3) so as to be able to perform revolving motion, the compression section (2) being driven by power recovered in the expansion section (1). A minimum clearance between a wrap (3L) of the fixed scroll (3) and a wrap (4L) of the orbiting scroll (4) in the expansion section (1) is set to be less than a minimum clearance between the wrap (3L) of the fixed scroll (3) and the wrap (4L) of the orbiting scroll (4) in the compression section (2).
