Abstract
A rotary fluid machine is provided in which a rotating shaft () fixed to a rotor () is rotatably supported on a fixed shaft () fixed to a casing (), sliding surfaces of the fixed shaft () and the rotating shaft () are lubricated by a first pressurized liquid-phase working medium, and sliding surfaces of the rotor () and a vane () are lubricated by a second pressurized liquid-phase working medium. By setting the pressure of the first pressurized liquid-phase working medium, which is supplied from an eleventh water passage (W), comparatively low and setting the pressure of the second pressurized liquid-phase working medium, which is supplied from a first water passage (W), comparatively high, wasteful leakage of the liquid-phase working medium past the sliding surfaces of the fixed shaft () and the rotating shaft (), where a comparatively small load is applied, can be prevented while enabling the sliding surfaces of the rotor () and the vane (), where a large load is applied, to be reliably lubricated with a high pressure liquid-phase working medium.
