ABSTRACT:
A rotary fluid machine is provided that includes a rotor chamber (14), a rotor (41), vanes (48) guided by vane channels formed in the rotor (41), and pistons (47) slidably fitted in cylinders (44) provided in the rotor (41). Rollers (71), which have a greaseless bearing structure and are provided on support shafts (48d) of the vane (48), are rollably engaged with annular channels (74) of a casing (11) so as to interconvert reciprocation of the pistons (47) and rotational movement of the rotor (41). By guiding water for a hydrostatic bearing that supports the vane (48) in the vane channel in a floating state from a recess (48e) of the vane (48) to a hydrostatic bearing (71) of the roller (71) via water passages (W19to W22), an outer member (71b) of the roller (71) is supported in a floating manner relative to an inner member (71a).
