摘要： A rotary fluid machine is provided that includes a rotor chamber (14), a rotor (41) housed within the rotor chamber (14), vanes (48) guided by vane channels formed in the rotor (41), and pistons (47) slidably fitted in cylinders (44) provided in the rotor (41). High temperature water of a hydrostatic bearing supporting the vane (48) in the vane channel in a floating state is retained by a plurality of pockets (48f) recessed in the surface of the vane (48), and the high temperature water retained by the pockets (48f) is supplied to the rotor chamber (14) during an expansion stroke as a result of radially outward movement of the vane (48) accompanying rotation of the rotor (41). The high temperature water supplied to the rotor chamber (14) is gasified into steam, and the pressure energy thereof improves the performance of the rotary fluid machine.

摘要： Pistons (41) are slidably received in a plurality of cylinders (39) disposed radially in a rotor (31), and a plurality of vanes (42) cooperating with the pistons (41) are disposed radially in the rotor (31), so that a vane chamber (54) is defined between a pair of the adjacent vanes (42). The radial movements of each of the pistons (41) and each of the vanes (42) are substantially stopped, so that the volumes of each of the cylinders (39) and each of the vane chambers (54) are not changed, for a period from the end of an exhaust stroke at which a gas-phase working medium is discharged from the cylinder (39) and the vane chamber (54) to the start of an intake stroke at which the supplying of the gas-phase working medium is started. Thus, it is possible to prevent the generation of a water hammer phenomenon due to a liquid-phase working medium confined in the cylinder (39) and the vane chamber (54).

摘要： A rotating fluid machine has first energy converting means including cylinders and pistons, and second energy converting means including vanes emerging from and submerging into a rotor in the radial direction. A gaseous phase working medium having leaked out of the higher pressure first energy converting means to a reservoir is effectively utilized instead of being discarded wastefully by feeding the leaked gaseous phase working medium to the lower pressure second energy converting means via a one-way valve and a junction chamber. Moreover, when the pressure in the reservoir is lower than that in the junction chamber, the one-way valve obstructs the gaseous phase working medium from flowing back, thereby preventing the efficiency of the second energy converting means from deteriorating.

摘要： A rotary fluid machine is provided that includes a rotor rotatably housed within a casing, a hollow rotating shaft (113) that rotates integrally with the rotor, and a fixed shaft (102) that is relatively rotatably fitted into the inner periphery of the rotating shaft (113); wherein the fixed shaft (102) is floatingly supported in the casing via a fixed shaft support spring (95) having an alignment action. When rotational runout of the rotor is transmitted to the fixed shaft (102) via the rotating shaft (113), the alignment action of the fixed shaft support spring (95) suppresses the rotational runout of the rotor, and any increase in the frictional resistance in a sliding section between the rotating shaft (113) and the fixed shaft (102) and the occurrence of abnormal wear can be prevented effectively, and the leakage of steam from a rotary valve (V) provided on the sliding surfaces of the rotating shaft (113) and the fixed shaft (102) can be reduced.
