    • The flow of hydraulic fluid induced by sliding movement of a piston in a cylinder is controlled by a pilot-type main valve and a pilot valve to generate damping force. The valve opening of the main valve is controlled by adjusting the pressure in a pilot chamber through the pilot valve. A volume compensating chamber is defined by a flexible disk member so as to face the pilot chamber. The volume compensating chamber is communicated with a reservoir through communicating passages. When the disk valve opens, the volumetric capacity of the pilot chamber reduces. At this time, the flexible disk member deflects toward the volume compensating chamber, thereby suppressing an excessive rise in pressure in the pilot chamber and preventing an unstable operation of the pilot valve and the main valve to obtain a stable damping force.
    • 由气缸内的活塞的滑动运动引起的液压流体的流动由先导式主阀和先导阀控制,以产生阻尼力。 通过先导阀调节先导室中的压力来控制主阀的阀门开度。 体积补偿室由柔性盘构件限定,以面向导向室。 体积补偿室通过连通通道与储存器连通。 当阀门打开时,先导室的容积减小。 此时,柔性盘构件朝向体积补偿室偏转,从而抑制先导室中的压力过度上升,并且防止先导阀和主阀不稳定地获得稳定的阻尼力。

    • A rotor (21) is an interior permanent magnet rotor formed of a rotor core (24) in which a plurality of permanent magnets (25) are embedded at predetermined intervals. First protruding portions (26) and second protruding portions (27) are formed on an outer peripheral face of the rotor, the first protruding portions (26) each opposing the vicinity of a central portion of each of the permanent magnets and having a substantially arc-shaped cross section protruding outward and the second protruding portions (27) each opposing the vicinity of an end portion of each of the permanent magnets and protruding outward. One first protruding portion and two second protruding portions correspond to one permanent magnet. The formation of the first and second protruding portions as described above on the outer peripheral face of the rotor makes it possible to sufficiently reduce the torque ripple and the noise caused by the distortion of air-gap magnetic flux distribution.
