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