A rotary fluid machine is provided that includes a rotor chamber (14), a rotor (41) housed within the rotor chamber (14), vanes (48) guided by vane channels formed in the rotor (41), and pistons (47) slidably fitted in cylinders (44) provided in the rotor (41). High temperature water of a hydrostatic bearing supporting the vane (48) in the vane channel in a floating state is retained by a plurality of pockets (48f) recessed in the surface of the vane (48), and the high temperature water retained by the pockets (48f) is supplied to the rotor chamber (14) during an expansion stroke as a result of radially outward movement of the vane (48) accompanying rotation of the rotor (41). The high temperature water supplied to the rotor chamber (14) is gasified into steam, and the pressure energy thereof improves the performance of the rotary fluid machine.
