    • A partition member is provided with an elastic body for absorbing hydraulic pressure fluctuation of the primary liquid chamber and a frame member for supporting an outer circumferential portion of the elastic body while aiming to prevent the rotation of the elastic body. A relief aperture communicating between the primary liquid chamber and the secondary liquid chamber is located on the outer circumferential side in the elastic body supporting region of the frame member. A relief valve for opening and closing the relief aperture is integrally formed on the outer circumferential side of the elastic body. The relief valve is formed of a pair of right and left relief valves. A width across flat sections are formed on a thick-walled outer circumferential section of the elastic body which is located between the right and left relief valves, such as to serve as a detent means.
    • 分隔构件设置有用于吸收主液室的液压波动的弹性体和用于支撑弹性体的外周部的框架构件,同时防止弹性体的旋转。 在主液室和辅液室之间连通的减压孔位于框架构件的弹性体支撑区域的外周侧。 在弹性体的外周侧一体地形成有用于打开和关闭释放孔的安全阀。 安全阀由一对左右安全阀构成。 平面部分的宽度形成在位于左右安全阀之间的弹性体的厚壁外周部分上,以用作制动装置。

    • A torque rod having an arm portion, a ring portion formed on each end of the arm portion in a longitudinal direction of the arm portion, and a rubber bushing that is integrally provided with the ring portion. The arm portion is formed from a material that is lower in specific gravity than iron. A weight is provided in a portion of the rubber bushing other than a principal spring portion. The principal spring portion, which absorbs principal vibration to be isolated, is formed by an elastic arm portion that extends radially outwardly from an inner cylinder located substantially in a center of the rubber bushing and is connected to the ring portion. An aperture, which is a separation space, is provided between the elastic arm portion and the ring portion.
    • 具有臂部的转矩杆,在臂部的纵向方向上形成在臂部的每个端部上的环形部分和与环部一体地设置的橡胶衬套。 臂部由比铁比铁重的比较低的材料形成。 在除了主弹簧部分之外的橡胶衬套的一部分中设置有重物。 吸收要隔离的主要振动的主弹簧部分由弹性臂部分形成,弹性臂部分从基本上位于橡胶衬套的中心的内筒径向向外延伸并连接到环部分。 在弹性臂部和环部之间设置有作为分离空间的孔。

    • A liquid sealed vibration isolating device has an elastically movable diaphragm capable of preventing elastic deformation of a relief valve to realize high damping while preventing a cavitation phenomenon. The relief valve is provided in the elastic movable diaphragm arranged in a partition member in order to open and close a leak passage so as to prevent occurrence of the cavitation phenomenon. The relief valve is integrally formed with a fixing portion of the elastic movable diaphragm. There is provided an upwardly open concavity that the relief valve faces. The relief valve is made thicker and provided with an opening and closing adjustment groove at a basal portion of its inclined wall. The opening and closing adjustment groove is formed with a locally thin bending portion functioning as a starting point of bending in an opening and closing operation of the relief valve.
    • 液体密封隔振装置具有能够防止安全阀的弹性变形以防止气蚀现象而实现高阻尼的弹性移动隔膜。 安全阀设置在布置在分隔构件中的弹性可动隔膜中,以便打开和关闭泄漏通道,以防止发生气蚀现象。 安全阀与弹性活动隔膜的固定部分整体形成。 提供了安全阀面对的向上开口的凹陷。 安全阀制成较厚,并在其倾斜壁的基部设置有开闭调节槽。 开关调节槽形成有局部薄的弯曲部,其作为安全阀的打开和关闭操作中的弯曲起点。
