| A rotary fluid machine is provided that includes a rotor chamber (14), a rotor (41), vanes (48) guided by vane channels formed in the rotor (41), and pistons (47) slidably fitted in cylinders (44) provided in the rotor (41).

By capturing water of a hydrostatic bearing, which supports the vane (48) in the vane channel in a floating state, by a U-shaped lubricating water guide channel (43g) formed on the end face of a rotor segment (43) and discharging it into the annular channels (74), the water is prevented from flowing into the rotor chamber (14) and decreasing the temperature of steam, thereby preventing the output of the rotary fluid machine from being degraded. | ||||||

| PROBLEM TO BE SOLVED: To discharge to a vane chamber only a liquid-phase operating medium from a reservoir part of a rotor from which the liquid phase operating medium and the gas phase operating medium leak. SOLUTION: A supplementary chamber 48h having a suction port 48i opened toward the inside in the radial direction of the rotor and a discharge port 48j opened toward the outside in the radial direction is formed inside a vane 48 slidably fitted to a vane groove 49 of the rotor. When the vane 48 moves inward in the radial direction, only the suction port 48i communicates with the reservoir part 78 to suck the liquid phase operating medium in the supplementary chamber 48h, and when the vane 48 moves outward in the radial direction, only the discharge port 48j communicates with the vane chamber 75 in the exhaust stroke to discharge the liquid phase operating medium in the supplementary chamber 48h. Thus, the suction port 48i and the discharge port 48j do not communicate with the liquid reservoir part 78 and the vane chamber 75 at the same time, whereby the gas phase operating medium in the liquid reservoir part 78 is inhibited from flowing to the vane chamber 75 through the supplementary chamber 48h, and the gas phase operating medium having usable pressure energy can be prevented from being discharged wastefully.

| A trap chamber having an air intake port opening inside a rotor in the radial direction and an exhaust port opening outside in the radial direction is formed within each vane slidably fitted to a vane groove of the rotor. When the vane has shifted inward in the radial direction, only the air intake port communicates with a reservoir to suck a liquid phase working medium into the trap chamber, and when the vane has shifted outward in the radial direction, only the exhaust port communicates with the vane chamber in the exhaust stroke to discharge the liquid phase working medium in the trap chamber. Since the air intake port and the exhaust port do not communicate with the liquid reservoir and the vane chamber at the same time, a gaseous phase working medium in the liquid reservoir is obstructed from flowing out to the vane chamber via the trap chamber, so that the gaseous phase working medium having still usable pressure energy is prevented from being wastefully discarded. | ||||||

| A rotary fluid pressure device (11) having a housing (13,31), inlet and outlet ports (21,23), a gerotor gear set (15), a valve member (51) and an input-output shaft (49). A seal assembly (73) is disposed radially between the shaft (49) and the housing (31). The seal assembly comprises, in the order of leakage flow from a case drain region (63), a high pressure shaft seal (77), an annular chamber (71) in which is disposed a rigid back-up member (79) for the seal (77), a drain passage (81) communicating from the annular chamber (71) to a case drain port (47), and a low pressure shaft seal (83). The back-up member (79) may cooperate with either the housing (31) or the seal (77) to define radial fluid passage means (87,89), so that any leakage flow past the high pressure shaft seal (77) flow to the case drain port (47). | ||||||

| PROBLEM TO BE SOLVED: To prevent a liquid-phase working medium for a hydrostatic bearing, which is supplied between a vane and a vane groove in a rotary fluid machine, from flowing into a vane chamber. SOLUTION: The rotary fluid machine comprises a rotor chamber 14, a rotor 41, 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 roller 71 is provided on a supporting shaft 48d of the vane 48 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 supports the vane 48 in a floating state in the vane groove, is trapped by a U-shaped lubricating water guide groove 43g formed on an end face of a rotor segment 43, and is exhausted into the annular groove 74, thereby preventing the water from flowing into the rotor chamber 14 to lower the temperature of vapor. In this manner, the lowering of an output of the rotary fluid machine is avoided. COPYRIGHT: (C)2003,JPO | ||||||

| PURPOSE: To surely prevent the leakage of a lubricant into a suction chamber by interposing a depression chamber midway of a route to connect a gear device chamber to the suction chamber in a rotary piston machine device in which an inner rotor is stored in an outer rotor in an eccentrically rotating manner, and both rotors are connected to each other by the gear device in an interlocking manner. CONSTITUTION: An outer rotor 4 rotatably stored about its major axis 6 in a casing 2 comprises rings 12 at both end parts in the axial direction and three engagement parts 14 to be coupled with an outer circumference of these rings 12 by screws 16. An inner rotor 24 in which an internal gear 20 is similarly coupled by the screws 16 and an external gear 22 engaged therewith is provided is rotatably provided on the outer rotor about an eccentric shaft 26 relative to the outer rotor 4. The external gear 22 is stored in a hole 30 of a casing cover 10, and the hole 30 is closed by a gear device cover 32 having a hollow chamber 34 useful for a depression chamber for the lubricant and the leaked air, and the chamber 34 is communicated with a gear device 28 and a suction chamber 49 respectively through connection ducts 40, 44.
