    • A flexible pipe coupling is disclosed. This coupling comprises a large diameter cylindrical hollow body, a pair of small diameter cylindrical hollow bodies each having one end portion disposed inside each end of the large diameter cylindrical hollow body on the same axial line, and an elastic sleeve member for connecting each end of the large diameter cylindrical hollow body to one end of each of the small diameter cylindrical hollow bodies. The elastic sleeve member is provided at its both ends adjacent to the cylindrical hollow bodies with protrusions each extending outwardly in the widthwise direction of the sleeve member at a radius of curvature corresponding to 0.1.about.0.4 times the thickness of the sleeve member, whereby the durability of the coupling is further improved.
    • 公开了一种柔性管接头。 该联接器包括大直径的圆柱形中空体,一对小直径的圆柱形中空体,每个小直径的圆柱形中空体的一端部设置在同一轴线上的大直径圆柱形中空体的每个端部的内侧,弹性套筒部件用于连接 大直径圆柱形中空体到每个小直径圆柱形中空体的一端。 弹性套筒构件在其两端附近设置有圆柱形中空体,其突出部沿着套筒构件的宽度方向向外延伸,其曲率半径对应于套筒构件的厚度的0.1倍,从而耐久性 的耦合进一步提高。

    • A fluid-tight sealing apparatus for sealing a tube to a cylindrical surface while subjected to axial, rotational and angular misalignments comprising a metallic, resilient sealing member on the tube having a ring portion with a curved surface for contacting the cylindrical surface and for forming a fluid-tight seal by means of an interference fit therebetween. The cylindrical surface can be the interior surface of a bore with the sealing member including a frustoconical portion having the ring portion at the larger end thereof and fitting into the cylindrical bore. The cylindrical surface can be the exterior surface of a conduit with the sealing member including a frustoconical portion having the ring portion at the smaller end thereof and fitting around the cylindrical conduit.
