    摘要: 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;91) 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;91) may cooperate with either the housing (31) or the seal (77) or the input-output shaft (49) to define a fluid passage (87,89;93,95), so that any leakage flow past the high pressure shaft seal (77) flows through the drain.

    摘要: 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). Rollers (71) provided on support shafts (48d) of the vane (48) are rollably engaged with annular channels (74) of a casing (11) so as to interconvert reciprocation of the pistons (47) and rotational movement of 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.

    摘要: An output shaft and arms are installed inside a cylinder. Pistons that are formed in an arc shape and rotatably connected to the arms slide and are displaced in the circumferential direction of the cylinder inside the cylinder. Inside the cylinder, a first pressure chamber on the arm side and second pressure chambers on the piston head portion side are provided. Third pressure chambers are provided on both sides of the cylinder. A pressure medium is supplied to one of the first pressure chamber and the second pressure chamber and discharged from the other, and the output shaft pivots in a rotational direction. When the pressure medium is supplied to the second pressure chambers, the pressure medium is also supplied to the third pressure chambers.
