A rotary fluid machine includes a first operating part ( 49 ) and a second operating part ( 57 ), which are groups of axial piston cylinders, wherein a rotary valve ( 61 ) for controlling the intake and discharge of a working medium to and from the first and second operating parts ( 49, 57 ) is formed from a first valve part that has a flat sliding surface ( 68 ) perpendicular to a rotational axis (L) of the rotor ( 27 ) and controls the intake and discharge of the working medium to and from the first operating part ( 49 ), and a second valve part that has a cylindrical sliding surface ( 71 ) centered on the rotational axis (L) of the rotor ( 27 ) and controls the intake and discharge of the working medium to and from the second operating part ( 57 ). Since the intake and discharge of the working medium to and from the first and second operating parts ( 49, 57 ) are controlled by the common rotary valve ( 61 ), the size of the rotary fluid machine can be reduced.
