Abstract: The thickness of an intermediate plate portion (31b) is smaller than the thickness of a stopper portion (31a). The thickness of a portion of a cylinder head gasket (20) having the stopper portion (31a) is set to be greater than the thickness of other portions of the cylinder head gasket (20). Before the cylinder head gasket (20) is provided between contact surfaces (12a, 13a), a space (S) is formed between the stopper portion (31a) and an adjustment stopper portion (32a), and the intermediate plate portion (31b) partially contacts the adjustment plate portion, and a bead (33a) contacts the adjustment plate portion (32b).

Abstract: The invention relates to a metal laminate gasket for use in an internal combustion engine, such as a cylinder head gasket. The gasket includes at least two metal plates, each having at least one hole to be sealed and a plurality of bolt holes. In one embodiment, the first metal plate includes an annular bead portion surrounding the at least one hole. The second metal plate is arranged to cover the recess of the bead portion of the first metal plate. A rigid synthetic resin layer fills a part of the recess of the bead portion of the first metal plate. The rigid synthetic resin layer serves to increase the thickness of the lamination of the gasket to enhance the sealing effect and serves to limit the degree of compression of the bead portion when the gasket is compressed. The rigid synthetic resin layer is covered with the first metal plate and the second metal plate, and thus does not come into direct contact with the joint surfaces.

The metal gasket comprises a plural number of metal plates and an annular rigid resin layer, each of the metal plates having opening(s) corresponding to the combustion chamber hole(s) of the gasket and bolt holes. The plural number of the metal plates are laminated so as to be overlaid on each other. The first metal plate disposed on the side of one outer surface of the gasket has a bent portion formed by turning back the peripheral portion of its opening, the bent portion having a curved portion and a flange portion. The bent portion encloses the peripheral portion of the opening of the second metal plate which is one of the metal plates laminated. The annular rigid resin layer is formed of, e.g., an epoxy resin.

The bent portion of the first metal plate encloses the peripheral portion of the opening of one of the remaining metal plates having a bead portion for surrounding the combustion chamber hole.

Abstract: A metal gasket is composed of a plurality of metal sheets superimposed one above the other and including a plurality of joints. Each of the joints includes a plurality of cut lines defining inner side edges of the metal sheets, and a bent portion located between the cut lines and having outer side edges which are frictionally engaged with the inner side edges of the metal sheets. The joints are oriented in different directions to accommodate a shear force.

Abstract: A coating composition for screen printing containing a fluorine rubber in a dissolved state is disclosed, wherein the solvent for the fluorine rubber comprises 60 to 100% by weight, based on the total solvent, of an ester ranging in boiling point from isoamyl acetate to isobornyl acetate. The coating composition which, even when formulated as a thick solution for providing a thick coat as used in the production of a metal gasket, hardly clogs the screen thereby making continuous coating possible.

Abstract: The filter for an inflator of the present invention includes a cylindrical compressed mesh unit, which is multi-folded in its substantially entire length, and the multi-folded mesh unit is provided by folding a cylindrical wire mesh knitted from a single metal wire by a predetermined length from its one or both end portions in the longitudinal direction, so as to be overlaid on the outer peripheral surface of the cylindrical wire mesh, and such a folded overlaying is repeated a plurality of times. Then, the cylindrical mesh unit thus constituted is compressed in its longitudinal direction. The above-mentioned compressed cylindrical mesh unit should have a cavity ratio of 70 to 80% in terms of cavity ratio C defined by the equation indicated below:C=(.rho.o-.rho.)/.rho.o.times.100(%).

Abstract: The disclosure relates to a catalytic converter for cleaning exhaust gas generated from automobiles or the like and more particularly to a structure for securing a catalyst carrier to a casing.In the converter, a casing for embracing, supporting and securing the catalyst carrier is provided with at least one end cover at the one end of the casing in the longitudinal direction thereof, the catalyst carrier is secured to the one end cover, but not secured to the remainder of the casing. The catalyst carrier may be secured to the end cover by sandwiching the flange portion of the catalyst carrier between the vertical step portion of the end cover and a pushing ring via buffering members. Alternatively, the catalyst carrier may be secured to the end cover by pushing a taper bushing having a wedge-shaped cross section into the space between the concave recessed portion provided on the surface of the catalyst carrier and the short pipe portion of the end cover.

Abstract: The present disclosure relates to a metal seal ring suitably used at pipe connection portions in exhaust pipe systems of automobile engines for example and a method of producing the same. The metal seal ring comprises a metal ring having a pipe-shaped cross section, and a heat-resistant composite gasket material ring filling the metal ring, wherein the composite gasket material ring is formed such that a sheet of the composite gasket material, such as a mixture of heat-resistant fiber and elastomer, a having reinforcing core material, such as a wire net and a perforated steel plate, therein, is slit to obtain a rectangular strip, that both longitudinal ends of the strip are joined to each other to form a ring, and that both fringes of the strip are butt-joined to each other to form a ring having a pipe-shaped cross section.

Abstract: Apparatus for assembling a grommet and a wire ring for forming a peripheral reinforcement of an engine head gasket opening. Grommets and wire rings are supplied one by one on different supply devices and retained at first and second article retaining positions, respectively. A movable head moves toward the second retaining position and picks up a wire ring. The head then conveys the wire ring to the second retaining position, where the wire ring is placed overlappingly on the grommet. Thereafter, another movable head having a deforming die is moved against the overlapped grommet and wire ring and deforms a flange of the grommet radially outwardly, whereby the grommet prevents separation of the wire ring therefrom. The thus assembled grommet and wire ring are conveyed to a machine for attaching them to the gasket.

Abstract: A metal gasket has an opening for allowing fluid to pass through the gasket, relatively small through-holes for receiving bolts, and a raised portion surrounding the entire circumference of the opening. The raised portion has a double-bead structure including an inner peripheral bead portion formed by an intermediate flat portion and a first frusto-conical portion which connects the intermediate flat portion with an inner peripheral flat portion, and an outer peripheral bead portion formed by the intermediate flat portion and a second frusto-conical portion which connects the intermediate flat portion with an outer peripheral flat portion. The second frusto-conical portion is inclined at an angle which is smaller than that at which the first frusto-conical portion is inclined.

Abstract: A joint has a first flange rigidly secured to the outer peripheral surface of an end portion of a first pipe and a second flange rigidly secured to the outer peripheral surface of an end portion of a second pipe. The first and second flanges are aligned with each other and joined together by nuts and bolts so that the first and second pipes are connected together and maintained in a hermetically sealed state by a closed loop-shaped sealing member clamped between the first and second flanges. The sealing member is fitted on the end portion of the second pipe which slightly projects from the second flange. The sealing member is formed by wrapping a thin metal sheet around heat resistant material and has an inner diameter which is equal to or slightly larger than the outer diameter of the second pipe. A frusto-conical surface aligned with the sealing member defines a portion of the inner peripheral surface of the first flange.
