Abstract:
1. A rotary fluid machine comprising a rotor chamber ( 14 ) formed in a casing ( 11 ), a rotor ( 41 ) rotatably housed within the rotor chamber ( 14 ), and a plurality of vane piston units supported on the rotor ( 41 ) so as to be radially moveable, the vane piston units comprising a vane ( 48 ) that is guided along a vane channel ( 49 ) formed in the rotor ( 41 ) and slides within the rotor chamber ( 14 ), and a piston ( 47 ) that is fitted slidably in a cylinder ( 44 ) provided in the rotor ( 41 ) and abuts against a non-sliding side of the vane ( 48 ); the pressure energy of a gas-phase working medium and the rotational energy of the rotor ( characterized in that a rotating shaft ( the pressure of the first pressurized liquid-phase working medium and the pressure of the second pressurized liquid-phase working medium being made different.
