摘要： In order to reduce driving power of an engine cooling system in which a cooling fan for cooling a radiator and a water pump are driven by a motor, according to the invention, a pump motor of the water pump 5 which circulates liquid coolant is used as a drive source of the cooling fan. An electromagnetic clutch is provided between the pump motor and the cooling fan, and when the liquid coolant exiting from an engine is at a predetermined temperature or higher, the electromagnetic clutch is brought into a connected state, whereas when the liquid coolant is at a temperature lower than the predetermined temperature, the electromagnetic clutch is brought into a disconnected state. When the liquid coolant is at a temperature lower than the predetermined temperature, and the vehicle speed is at a predetermined speed or higher, the electromagnetic clutch is brought into a connected state, and a rotational force of the cooling fan receiving driving wind is transmitted to the pump motor to reduce its load.

摘要： A multi-lobe bearing is of simple construction such that a foil sheet in the form of a closed loop is arranged on a journal shaft by joining both ends of two sheets together, with a bearing gap therebetween and filling a viscoelastic body in an air gap between the foil sheet and an inside of a bearing holding member, whereby the bearing gap between the journal shaft and the foil sheet is configured to be liable to generate a fluid pressure. Also, the bearing is simply constructed to be made easy in assembly, and in particular, appropriate in bearing the journal shaft having a small diameter.

摘要： A multi-lobe foil gas bearing which can accomplish high accuracy rotation by means of a stable fluid lubricating film without being affected by a rotational position or a driving system of a journal at the time of starting is provided. Since two foils are arranged with different phases in a circumferential direction so that each vertex part of one of the two foils is positioned in an arc surface part of the other foil in a plan view seen from a shaft end of the journal, a part having low rigidity and a part having high rigidity of the multi-lobe foil gas bearing compensate each other to eliminate a local part having low bearing rigidity. As a result, it is possible to eliminate a phenomenon such as moving or leaning of the journal at the time of starting, while the fluid lubricating film can exist over the entire circumferential surface of the journal to keep stable high accuracy rotation of the journal.
摘要翻译：提供了一种多叶片箔气体轴承，其可以通过稳定的流体润滑膜实现高精度的旋转，而不受起动时的轴颈的旋转位置或驱动系统的影响。由于两个箔片在圆周方向上具有不同的相位布置，使得两个箔片中的一个的每个顶点部分在从轴颈的轴端看到的平面图中位于另一箔片的弧形表面部分中，多片箔气体轴承的低刚性和高刚性部分相互补偿以消除具有低轴承刚度的局部部件。结果，可以消除在起动时轴颈移动或倾斜的现象，同时流体润滑膜可以存在于轴颈的整个圆周表面上，以保持轴颈稳定的高精度旋转。
