    摘要: A metal annular gasket comprising an annular metal base plate; a compound layer integrally laminated on both surfaces of the annular metal base plate, the compound layer being made of synthetic resin or a rubber material mixed with a fiber material; and an annular seal layer having a circumferential covering portion which covers the inner circumferential edge of the annular metal plate and the inner circumferential edge of both compound layers, the compound layer being made of synthetic resin or a rubber material. The annular seal layer is formed such that the surface of the annular seal layer is so connected to the surfaces of the compound layer as to provide smooth transition in its thickness direction.

    摘要: A heat-resistant, thermally stable, ductile piston ring for an internal combustion engine having a structure comprised at least partially of fiber reinforced ceramic matrix composite (FRCMC) material. The FRCMC material includes a polymer-derived ceramic resin in its ceramic state and fibers. The ceramic portion of the material for the most part provides the heat-resistance of the FRCMC material, while the fibers produce a desired degree of ductility in the FRCMC material. Filler materials may incorporated into the piston ring to produce the desired degree of hardness and/or coefficient of friction.

    摘要: An uncooled turbine outer air is comprised of a combination of monolithic ceramics with high temperature capability and oxidation and creep resistance, and a fiber reinforced ceramic composite with high fracture toughness. In a preferred embodiment of the invention, a fiber reinforced ceramic composite of silicon carbide and aluminum borosilicate is infiltrated by chemically vapor deposited silicon carbide. The infiltration process is continued until the composite develops a monolithic layer of silicon carbide. An additional layer is deposited on the monolithic ceramic to provide additional thermal protection.

    摘要: The gasket of the present invention includes a length of rope having a circumferential outer surface. The rope is formed at least substantially by a plurality of woven fibrous yarns. The gasket further includes an elastomeric coating adhered to the circumferential outer surface of the rope along the length of the rope. The coating is applied to more than one-half and less than all of the circumferential outer surface so as to expose part of the circumferential outer surface along a single side of the rope. A layer of contact adhesive may be applied directly to the exposed part of the circumferential outer surface to adhere the gasket to a non-adhesive surface. The gasket is beneficially employed between sections of a sectional boiler.

    摘要: A flexible seal assembly has an elastomeric body with a convoluted intermediate portion for accommodating pivotal movement about the center of a spherical joint and an integral radial seal lip for accommodating rotational movement about a central axis of the joint. The seal lip extends from an inner diameter portion of elastomeric body in proximate relationship to a rigid plastic lip restraining ring which is molded into such inner diameter portion such that flexure loads are carried by the restraining ring and have no effect on the seal lip.

    摘要: A flexible, fluid-tight seal assembly for sealing the gap between a duct and a wall where the duct passes through an opening in the wall. The seal assembly includes an annular housing affixed to and centered on the opening in the wall. The housing includes a circular recess opening inwardly toward the duct. Contained in the recess is a carrier ring supporting a set of three O-rings set into cooperable O-ring grooves in the carrier ring. One O-ring groove opens inwardly toward the duct such that the associated O-ring snugly encircles the duct so as to provide a seal between the duct and the carrier ring. The other two O-rings are set into grooves which face in opposite directions such that the two O-rings snugly abut the walls of the recess to provide a seal between the carrier ring and the housing. The carrier ring is movable laterally in the recess of the housing so as to permit lateral movement of the duct with respect to the wall. Also, the O-ring sealed between the carrier ring and the duct permits the duct to undergo axial motion with respect to the carrier ring and the wall. Together, the three O-rings also permit the duct to undergo limited rotational motion about axes of rotation lying in the plane of the wall opening and extending transversely with respect to the duct. The seal assembly provides an effective gas- and liquid-tight seal between the duct and the wall and may be particularly adapted to accommodate a hot air duct in an airplane.

    摘要翻译: 用于密封管道和壁之间的间隙的柔性,流体密封的密封组件,其中管道穿过壁中的开口。 密封组件包括固定在壁上的开口上并居中的环形壳体。 壳体包括朝向管道向内开口的圆形凹槽。 在凹槽中包含一个载体环,其支承一组三个O形环,该三个O形环设置在载体环中的可配置的O形环槽中。 一个O形环槽朝向管道向内打开,使得相关联的O形环紧密地环绕管道,以便在管道和承载环之间提供密封。 另外两个O形环被设置成面向相反方向的槽,使得两个O形环紧密地邻接凹槽的壁,以在承载环和壳体之间提供密封。 承载环在壳体的凹部中横向移动,以允许管道相对于壁的横向移动。 此外,密封在承载环和管道之间的O形环允许管道相对于承载环和壁经历轴向运动。 三个O形圈一起也允许管道围绕位于壁开口的平面中并且相对于管道横向延伸的旋转轴进行有限的旋转运动。 密封组件在管道和壁之间提供有效的气体和液密密封,并且可以特别适于容纳飞机中的热空气管道。

    摘要: This invention is directed to an improved method of forming and installing polytetrafluoroethylene (PTFE) lip seals and to a novel PTFE lip seal. The lip seals are formed by taking a flat, annular PTFE washer having given dimensions and stretching it over a tapered mandrel by pushing it toward the direction from which the fluid pressure will come in the sealing operation. The finished PTFE lip seals have a curved configuration. Both O.D. and I.D. lip seals are disclosed.
