    摘要： A gas governor apparatus comprises an inner casing (4) removably mounted on an outer casing (1). Further, a driving mechanism (5, 6, 7, 9, 10, 13) for driving a valve body (12) to control pressure and flow rate of fluid between the valve body and a valve seat (17) formed in the inner casing comprises a drive motor (5) and a drive shaft (6). The drive shaft has a dual drive sleeve construction (10, 13) where an outer drive sleeve (13) and the valve body are constituted as a rotating drive mechanism and an inner drive sleeve (10) and the outer drive sleeve are constituted as an axial shifting drive mechanism. The outer and inner drive sleeves are axially shiftable by means of an elastic member (11). The valve body and the inner casing are maintained sealingly by dual expansible members (19a, 19b). A flow passage is defined by the dual expansible members and the inner casing. An intermediate pressure chamber (20) is switched to communicate with one of a primary pressure circuit (23, 24) communicating to primary pressure (P₁) and a secondary pressure circuit (25) communicating to secondary pressure (P₂) by means of a three-way switching valve (22) to permit introduc­tion of the fluid into the intermediate pressure chamber.

    摘要： An increase in the temperature of a sliding bearing can be suppressed even when the bearing is used under a high load. It is possible to reduce the temperature of the bearing and prevent the bearing from burning and being damaged. The bearing is divided into two and composed of a bearing liner 3; 103 and a bearing base metal 4; 104. The bearing liner is provided on an inner circumferential side of the bearing, and the bearing base metal 4; 104 is provided on an outer circumferential side of the bearing. A lower bearing liner 3a; 103a of the bearing liner 3; 103, which is located on a load-receiving side 3a; 103a, has a cooling groove formed in an outer circumferential surface thereof and extending along a circumferential direction thereof. A lubricant is cooled in the cooling groove 6, 7; 106and supplied to reduce the temperature of a shaft-sliding surface 16; 127 of the bearing. The lubricant that increases in temperature due to the cooling and has low viscosity is supplied to the bearing.

    摘要： Disclosed is a highly reliable tilting-pad journal bearing device constructed to suppress vibration by improving a damping effect through a lubricating oil film, and thus to improve cooling performance for bearing pads without increasing the number of parts required.
    The tilting-pad journal bearing device includes a plurality of bearing pads (2) in a circumferential direction at an inner circumferential side of a casing (1), and supports a rotary body (4); at least one of the bearing pads (2) includes an oil-through groove (8) circumferentially extending along an outer circumferential surface of the bearing pad, the groove circumferentially extending through from an end face of the pad to its opposite end face.
