<p>A rotary shaft (113) fixed to a rotor (41) is rotatably supported on a fixed shaft (102) fixed to a casing (11), and the slide surface of the fixed shaft (102) and rotary shaft (113) are lubricated by a first pressurized liquid phase working medium, while the slide surface of the rotor (41) and vane (48) are lubricated by a second pressurized liquid phase working medium. The first pressurized liquid phase working medium fed from an eleventh water channel (W11) is set at a relatively low pressure, and the second pressurized liquid phase working medium fed from a first water channel (W1) is set at a relatively high pressure, thereby making it possible to prevent useless leakage of the liquid phase working medium from the slide surfaces of the fixed shaft (102) and rotary shaft (113) that are subjected to a relatively low load while reliably lubricating the slide surfaces of the rotor (41) and vane (48) that are subjected to a high load by the high pressure liquid phase working medium.</p> |
