A flat sealing gasket includes a mat of non-woven material having opposite faces; a polymerized impregnating agent distributed with the material and an overlay on at least one of the mat faces. The overlay which comprises a hardened, pressure-resistant polymer material is sunken into the mat to a substantial extent of the mat thickness.

Cylinder head gasket having overlays in end zones

A flat sealing gasket includes an opening defined by a gasket edge and a sheet metal armor framing the gasket edge. The armor at least partially encloses an annular space which is situated radially inwardly of the gasket edge and is generally concentric with the gasket opening. Further, a graphite filling is accommodated in the annular space.

A sealing ring, having a ring body made, for example, of high-temperature resistant compressed metal fibers includes a roughened surface adapted to be pressed against and displaced by sliding relative to a counter-face.

Sealing ring

A sealing ring having at least one jacket face serving as a slide surface is produced of fibers and sliding agent that are passed to one another, with the fibers being relatively short fibers.

Sealing ring for sealing an articulated connection

An impregnated soft, flat sealing gasket made by a process including the consecutive steps of preparing a gasket material selected from the group consisting of organic fibers, inorganic fibers, synthetic fibers and mixtures thereof and a binder; forming a fiber mat from the gasket material; impregnating the fiber mat with a cross-linkable impregnating agent and at least partly cross-linking the impregnating agent in the fiber mat; and adding to the fiber material, in a fine distribution therein, a duromer synthetic resin prior to the impregnating step and as early as simultaneously with the preparing step.

Impregnated soft, flat gasket and manufacturing method

A method of making a flat gasket comprising a non-woven mat having opposite faces, including the steps of impregnating the mat with a polymerizable liquid impregnating agent and applying to at least one part of at least one mat face a coating containing a polymerizable polymer material. The coating is applied to the impregnated mat prior to polymerization of the impregnating agent. The impregnating agent and the coating are simultaneously polymerized in one operation.

Impregnated flat sealing gasket and method of making the same

A sealing ring having at least one jacket face serving as slide face, the ring comprising pressed together fiber materials and slide materials, with the ring containing as a third component up to 10 parts by weight of such finely dispersed additives which chemically react with the fibers under the pressure and/or the development of heat resulting from friction stresses.

A flat sealing gasket, such as a cylinder head gasket, for an internal combustion engine, has at least one opening, a cross-sectionally generally U-shaped armor framing the opening. The armor has legs straddling marginal edge zones of the gasket defining the opening. Each armor leg has an inner face in engagement with the gasket and an outer face oriented away from the gasket. A low-friction coating is provided on the outer face of at least one of the armor legs. Those sealing faces of the gasket which are externally of the armor are substantially free from the low-friction coating.

Sealing gasket

A sealing gasket has at least one framed throughgoing opening; the frame is formed of at least two superposed bent sheet metal border flanges which have a U-shaped cross section and which have legs of unlike lengths. The border flanges fully overlap the soft material of the gasket without forming an appreciable hollow space underneath the legs.
