摘要： Two steel pipes are each connected to a mounting flange for joining the two pipes, the flanges in one embodiment being fixed stationary to each other and in a second embodiment fixed movable relative to each other. A compressed knitted wire mesh seal is between the two flanges in a dynamic embodiment. Each flange has a spherical inner concave or outer convex surface and the seal has an inner concave and outer convex spherical surface. The seal outer convex spherical surface has a radius smaller than the mating flange concave inner surface. The origins of the two radii are offset. The seal inner concave spherical surface has a radius that is larger than the mating spherical outer convex surface of the corresponding flange. The seal contacts the two flanges in an annular set of pressure points to provide enhanced sealing action. In a second embodiment, the pipes are fixed stationary relative to each other and the outer flange is connected to a pipe spherical segment which segment has an inner concave spherical surface which engages the seal outer convex surface. The radii of the mating surfaces are different to provide enhanced sealing pressure points at the tangency of the mating surfaces.
摘要翻译：两个钢管各自连接到用于接合两个管的安装凸缘，一个实施例中的凸缘彼此固定固定，并且在相对于彼此固定的第二实施例中固定。在动态实施例中，压缩的针织丝网密封件位于两个凸缘之间。每个凸缘均具有球形内凹面或外凸面，密封件有内凹面和外凸球面。密封外凸球面的半径小于配合法兰凹面内表面。两个半径的起点被偏移。密封内凹球面的半径大于相应凸缘的配合球面外凸面。密封件将两个法兰接触在一组环形压力点中以提供增强的密封作用。在第二实施例中，管道相对于彼此固定固定，并且外凸缘连接到管状球形段，该段具有与密封件外凸表面接合的内凹球面。配合表面的半径是不同的，以便在配合表面的切线处提供增强的密封压力点。

摘要： Compressed wire filament(s) form a seal that seals the joint between first and second pipes of an automotive exhaust system secured by bolted together first and second flanges. The seal is initially attached to the first pipe and first flange in an intermediate assembly by an interface connection that prevents the seal from axially moving off of the first pipe prior to final assembly to the second pipe and second flange. A male projection is at the end region of the first pipe outer surface to which the seal is attached. The first flange abuts the seal at a planar seal interface. The seal has a bore with a longitudinal channel portion for initially axially engaging the projection and a transverse channel portion medially the seal bore for receiving the projection by rotation of the seal after the projection is axially displaced within the seal bore. The transverse channel portion may be tapered to wedge the projection in place to preclude accidental disengagement of the seal prior to final assembly to the mating second flange and second pipe. The joint in one embodiment articulates and in a second embodiment the joint is fixed and does not articulate. Various embodiments are disclosed.
摘要翻译：压缩丝丝形成密封件，其密封通过螺栓连接在一起的第一和第二法兰固定的汽车排气系统的第一和第二管之间的接头。密封件最初通过接口连接件附接到中间组件中的第一管和第一凸缘，其在最终组装到第二管和第二凸缘之前防止密封件从第一管轴向移离。阳突起位于密封件附接到的第一管外表面的端部区域。第一凸缘在平面密封界面处邻接密封件。密封件具有一个带有纵向通道部分的孔，用于最初轴向地接合突出部，中间是横向通道部分，该密封孔用于在凸起在密封孔内轴向移位之前通过密封件的旋转来接收突出部。横向通道部分可以是锥形的，以将突起楔入到位以防止密封件在最终组装之前意外脱离到配合的第二凸缘和第二管。一个实施例中的关节铰接，并且在第二实施例中，关节固定并且不铰接。公开了各种实施例。
