<p>Rotary fluid machinery, comprising a rotor chamber (14), a rotor (41), a vane (48) guided by a vane groove formed in the rotor (41), and a piston (47) slidably fitted to a cylinder (44) installed in the rotor (41), wherein a roller (71) installed on the pivot shaft (48d) of the vane (48) is rollingly fitted to the annular groove (74) of a casing (11) to convert the reciprocating motion of the piston (47) into the rotating motion of the rotor (41), and vice versa, water in a static pressure bearing for supporting the vane (48) in the vane groove in floated state is trapped by a U-shaped lubricating water guide groove (43g) formed in the end face of a rotor segment (43) and discharged to the annular groove (74), whereby the water is prevented from flowing into the rotor chamber (14) to lower the temperature of vapor so as to avoid the lowering of output of the rotary fluid machinery.</p> |
