摘要： A device for rotating body windage loss reduction, capable of rotating a rotating body at a high peripheral speed in an environment at atmospheric pressure or close to atmospheric pressure while reducing fluid resistance loss at a low cost by making use of the conventional bearing technology, is implemented, thereby enhancing efficiency of an energy storage device such as, for example, a flywheel, and so forth. The device is provided with a rotating body held rotatably; and a covering rotating body installed on the outer side of the rotating body so as to enclose the same, held rotatably and coaxially with the rotating body. Further, optional plural numbers of the covering rotating bodies installed coaxially with the rotating body and covering the outer side of the device for rotating body windage loss reduction are provided on top of each other in sequence. Still further, bearing means are provided between the rotating body and the covering rotating body adjacent thereto or between the covering rotating bodies adjacent to each other, and bearings for the respective covering rotating bodies are disposed in series in relation to bearings for the rotating body. In addition, by filling up the interior of a case with hydrogen gas or helium gas, lower in density than air, windage loss can be further reduced.

摘要： A hydraulic system 10 of the present invention has a hydraulic pump driven by a driving source 14, a hydraulic pump motor 52 driven by an operating oil discharged from the hydraulic pump and flowing in an oil path 50, an inertial body 60 connected to a rotary shaft of the hydraulic pump motor, an oil path 62 connected between an outlet port of the hydraulic pump motor and a load 22, an unloading oil path 64 branched from the oil path 62, and an on-off valve 68 inserted in the unloading oil path. In this configuration, as the on-off valve is opened and closed, a high pressure is generated in the oil path 62 by making use of kinetic energy of the inertial body. The inertial body is driven by hydraulic power and the inertial body is separated from the driving source, which also provides an effect of increasing degrees of freedom for an instrument layout.

摘要： A hydraulic apparatus (10), characterized by comprising a hydraulic pump driven by a drive source (14), a hydraulic pump/motor (52) driven by the hydraulic oil discharged from the hydraulic pump and flowing through an oil passage (50), an inertia body (60) connected to the rotating shaft of the hydraulic pump/motor, an oil passage (62) connected between the outflow port of the hydraulic pump/motor and a load (22), an unload oil passage (64) branched from the oil passage (62), and an open/close valve (68) installed i n the unload oil passage, wherein when the open/close valve is opened and closed, a high pressure is generated in the oil passage (62) by utilizing th e kinetic energy of the inertia body and, since the inertia body is driven by a hydraulic power, the drive source is separated from the inertia body to increase the degree of freedom of the layout of the apparatus.
