摘要： PROBLEM TO BE SOLVED: To improve the performance of a rotary fluid machine by efficiently utilizing heat energy of a liquid-phase working medium for a hydrostatic bearing supplied between a vane and a vane groove. SOLUTION: The rotary fluid machine comprises a rotor chamber 14, a rotor 41 accommodated in the rotor chamber 14, the vane 48 guided by the vane groove formed on the rotor 41, and a piston 47 slidably engaged with a cylinder 44 provided in the rotor 41. A high-temperature water for a hydrostatic bearing, by which the vane 48 is supported in a floating state in the vane groove, is retained in a plurality of pockets 48f concavely formed on a surface of the vane 48. By a radially outward movement of the vane 48 along with the rotation of the rotor 41, the high-temperature water retained in the pockets 48f is supplied into the rotor chamber 14 in an expansion stroke. The high- temperature water supplied into the rotor chamber 14 is vaporized to become vapor, and the pressure energy generated in this manner is utilized to improve the performance of the rotary fluid machine.

摘要： PROBLEM TO BE SOLVED: To change exhaust timing in a rotary fluid machine using a simple structure. SOLUTION: The rotary fluid machine has a rotor accommodated in a casing, and a side surface of the rotor is sealed by a ring seal 79' which is rotatably engaged with a circular seal groove 76 formed on the casing. A notch 79c is formed on a part of a peripheral surface of the ring seal 79', thereby providing an arcuate exhaust passage 93 between the circular seal groove 76 and the ring seal 79'. By rotating the ring seal 79' using exhaust timing changing means 70, an inlet end of the exhaust passage 93 is shifted between positions (a) and (a'). In this manner, the timing when a vane chamber rotated along with the rotor communicates with an exhaust port 91 via the exhaust passage 93 and a recess 11a of the casing is continuously changed.

摘要： PROBLEM TO BE SOLVED: To supply a pressurized liquid-phase working medium under an appropriate pressure to a plurality of lubrication parts in a rotary fluid machine, and ensure a necessary lubrication performance while avoiding a vain leakage of the liquid-phase working medium. SOLUTION: A rotary 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 rotary shaft 113 are lubricated with a first pressurized liquid-phase working medium, and sliding surfaces of the rotor 41 and a vane 48 are lubricated with a second pressurized liquid-phase working medium. The first pressurized liquid-phase working medium supplied through an eleventh water passage W11 is set under a relatively low pressure, and the second pressurized liquid-phase working medium supplied through a first water passage W1 is set under a relatively high pressure. In this manner, the sliding surfaces of the rotor 41 and the vane 48, where a large load is applied, are surely lubricated by the high-pressure liquid-phase working medium, while a vain leakage of the liquid- phase working medium from the sliding surfaces of the fixed shaft 102 and the rotary shaft 113, where a relatively small load is applied, is prevented.

摘要： PROBLEM TO BE SOLVED: To compensate for the influence of rotational oscillation of a rotor in a rotary fluid machine when a hollow rotary shaft integrated with the rotor is rotatably supported on an outer periphery of a fixed shaft fixed to a casing. SOLUTION: In the rotary fluid machine comprising the rotor rotatably accommodated in the casing, the hollow rotary shaft 113 rotated together with the rotor, and the fixed shaft 102 relatively rotatably engaged with an inner periphery of the rotary shaft 113, the fixed shaft 102 is supported in a floating manner on the casing via a fixed shaft supporting spring 95 having an alignment function. When the rotational oscillation of the rotor is transmitted via the rotary shaft 113 to the fixed shaft 102, the rotational oscillation of the rotor is restrained by the alignment function of the fixed shaft supporting spring 95. Also, increase in frictional resistance or occurrence of extraordinary wear in sliding regions of the rotary shaft 113 and the fixed shaft 102 is effectively avoided. Furthermore, leakage of vapor from a rotary valve V provided on sliding surfaces of the rotary shaft 113 and the fixed shaft 102 is reduced.

摘要： PROBLEM TO BE SOLVED: To ensure a lubrication performance of a roller which is provided in a vane piston unit of a rotary fluid machine, and to enhance its durability while making the roller greaseless. SOLUTION: The rotary fluid machine comprises a rotor chamber 14, a rotor 41, a vane 48 guided by a vane groove formed on the rotor 41, and a piston 47 slidably engaged with a cylinder 44 provided in the rotor 41. The roller 71 having a greaseless bearing structure is provided on a supporting shaft 48d of the vane 48 in order to mutually convert the reciprocating motion of the piston 47 and the rotary motion of the rotor 41, and is rotatably engaged with an annular groove 74 of a casing 11. Water for a hydrostatic bearing, which supports the vane 48 in a floating state in the vane groove, is led from a recess 48e of the vane 48 via water passages W19 to W22 to a hydrostatic bearing 70 of the roller 71, thereby supporting an outer member 71b of the roller 71 in a floating state relative to an inner member 71a thereof.

摘要： PROBLEM TO BE SOLVED: To increase a control accuracy of a stroke position of a spool with a linear solenoid, by compensating an axial force generated by a dynamic pressure of an oil which has flown into a groove from an input port of a spool valve.SOLUTION: A groove G3 bringing an input port P4 into communication with an output port P5 of a spool 20 includes a first wall part W1 of one side of a spool 20 and a second wall part W2 of the other end side. Then, the oil which has flown from an input port P4 into a groove G3 collides with the second wall part W2, and then an undesirable axial force F2 applying force to the spool 20 toward the other end side is generated. However, since the oil which has collided with the second wall W2 and returned from the other end side to one end side is guided to a third wall part W3 of the output port P5 and collides with the first wall part W1 about perpendicularly, an axial force F1 which presses the first wall part W1 and applies force to the spool 20 toward one side is generated, and the axial force F1 cancells the axial force F2; thereby the control accuracy of the stroke position of the spool 20 is increased.
