    • A rotary damper for stabilization of a damping and temperature characteristic without impairing a temperature compensation function and facilitates a lubricating operation. The damper includes a bore for a damping force generating mechanism as a single communication flowpassage and a bore for a temperature compensation mechanism arranged in a line in a casing. The damping force generating mechanism is divided into two sets of damping elements with damping valves and return valves, arranged in series in the communication flowpassage with back surfaces of the damping valves and are oppositely positioned. A portion of the communication flowpassage between the damping valves is communicated with an oil chamber of a temperature compensation mechanism by an oil passage. A side panel is provided with a lubricating port toward the oil chamber of the temperature compensation mechanism. A side oil passage branched from the lubricating port is communicated with one end of the communication flowpassage, and the lubricating port and the side oil passage are simultaneously opened and closed by a cut plug. Seal members fitted in vanes and separating blocks are provided with concave portions for forming projecting lips on the inner and outer peripheral surfaces thereof. The concave portion at an angular portion on the outer peripheral surface is buried to form a flat surface, or the concave portion is formed to be shallow, to lower the height of the projecting lip, and the rigidity in that portion is increased to enhance the wear resistance.
    • 一种用于稳定阻尼和温度特性而不损害温度补偿功能并有助于润滑操作的旋转阻尼器。 阻尼器包括用于作为单个连通流动的阻尼力产生机构的孔和用于设置在壳体中的管线中的温度补偿机构的孔。 阻尼力产生机构被分为两组阻尼元件,其阻尼阀和止回阀与阻尼阀的后表面串联连接并相对定位。 阻尼阀之间的连通通道的一部分通过油路与温度补偿机构的油室连通。 侧板设置有朝向温度补偿机构的油室的润滑口。 从润滑口分支的侧油通道与连通流路的一端连通,润滑口和侧油通道同时被切断塞打开和关闭。 安装在叶片和分离块中的密封构件设置有用于在其内外周表面上形成突出唇缘的凹部。 外周面上的角部的凹部被埋入以形成平坦面,或者凹部形成为较浅,以降低突出唇部的高度,并且增加该部分的刚性,以提高 耐磨性。

    • A dynamic damper 70 allows for a stable operation of a sub-clutch without complicating a structure of the sub-clutch. The dynamic damper 70 of a coupling mechanism 91 for coupling a crankshaft 90 of an engine and an input shaft 9 of a transmission includes a mass member 71, a sub-clutch 73 and an annular rubber member 72. The mass member 71 can rotate in accordance with rotation of the input shaft 9. The sub-clutch 73 has a release member 86 for release, and releases interlocking between the input shaft 9 and the mass member 71 when the crankshaft 90 and the input shaft 9 are released from each other by releasing the biasing state of a pressure plate 4c. The release member 86 is in contact with the pressure plate 4c and moves in accordance with an axial movement of the pressure plate 4c. The annular rubber member 72 elastically couples the input shaft 9 and the mass member 71 in the rotating direction when they are in the interlocked state.
