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.

摘要： A rotating fluid machine is provided with a rotor chamber, a rotor accommodated in the rotor chamber, and vanes guided by vane grooves formed in the rotor. A U-shaped vane seal is held by a seal holding groove formed in the end face of each of the vanes. The opposite ends of the vane seal are fitted into slits in seal ancillary members which are fitted into engaging holes formed in the end faces of each of the vanes. The seal ancillary members are pressed by springs toward the inner circumferential face of the rotor chamber. The pressure of a gaseous phase working medium introduced into the bottom parts of the seal holding grooves is restrained from leaking out of the ends of the vane seal by the seal ancillary members. Thus, sealing performance can be secured by pressing the vane seal against the inner circumferential face of the rotor chamber.

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); in which the rotating shaft (113) is formed by shrink-fitting an outer sleeve (21) made of metal around the outer periphery of an inner sleeve (85) made of ceramic, etc. having a lower coefficient of thermal expansion than that of metal, and the fixed shaft (102) is formed by shrink-fitting an outer sleeve (88) made of metal around the outer periphery of an inner sleeve (87) made of ceramic, etc. having a lower coefficient of thermal expansion than that of metal. Since thermal expansion of the outer sleeves (21, 88) fitted around the outer peripheries of the inner sleeves (85, 87) is suppressed due to residual tensile stress of the outer sleeves (21, 88), intimate contact between the outer sleeves (21, 88) and the inner sleeves (85, 87) can be maintained.

摘要： A Rankine cycle system is provided in which, with regard to a given relationship between the pressure (Pevp) and the temperature (Tevp) of a vapor that is taken into an expander (4) that includes a cylinder chamber in a first stage and a vane chamber in a second stage, the chambers being disposed in line, the expansion ratio of the vapor that the expander (4) takes in and discharges is set at a predetermined expansion ratio (ε) according to the given relationship so that the pressure (Pexp2) and the temperature (Texp2) of the vapor that is discharged from the expander (4) coincide with target values, thereby making the expander (4) and the condenser (5) exhibit maximum performance. Since the vapor within the cylinder chamber in the first stage is in a superheated vapor region and contains no water, the phenomenon of water hammer will not be caused in the cylinder chamber. Furthermore, since the vapor at the exit of the vane chamber is in a saturated vapor region and contains water, the vane chamber can be lubricated and sealed by means of the water.

摘要： In a rotary fluid machine including pistons (37) reciprocally received in cylinders (33) provided in a rotor (27), and vanes (44) fitted in vane grooves provided in the rotor (27) for reciprocal movement, the rotor (27) includes a rotor core (31) which is supported on a rotary shaft (21) and in which the cylinders (33) are accommodated, and twelve rotor segments (32) separated in a circumferential direction and fixed to surround an outer peripheral surface of the rotor core (31); and each of the vane grooves (43) is defined between the adjacent rotor segments (32). Thus, the dimensional accuracy of the vane grooves (43) can be enhanced without need for a special accurate working or processing. In addition, the transmission of heat from the rotor core (31) of a relatively high temperature to the rotor segments (32) of a relatively low temperature can be blocked, whereby the dissipation of the heat to the outside of the rotor (27) can be suppressed, leading to an enhancement in heat efficiency, and moreover, the thermal deformation of various portions of the rotor (27) can be moderated.

摘要： A rotary fluid machine is provided in which a rotating shaft (113) fixed to a rotor (41) is rotatably supported on a fixed shaft (102) fixed to a casing (11), sliding surfaces of the fixed shaft (102) and the rotating shaft (113) are lubricated by a first pressurized liquid-phase working medium, and sliding surfaces of the rotor (41) and a vane (48) 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 (W11), comparatively low and setting the pressure of the second pressurized liquid-phase working medium, which is supplied from a first water passage (W1), comparatively high, wasteful leakage of the liquid-phase working medium past the sliding surfaces of the fixed shaft (102) and the rotating shaft (113), where a comparatively small load is applied, can be prevented while enabling the sliding surfaces of the rotor (41) and the vane (48), where a large load is applied, to be reliably lubricated with a high pressure liquid-phase working medium.
