A heat exchanger suitable for cooling exhaust gases and a method of making same are disclosed. The heat exchanger includes an outer casting member having first and second ends and forming a housing and a plurality of channel members forming alternating first and second flow channels for the flow of an exhaust gas through the first flow channels and coolant through the second flow channels. The channel members form a core having first and second ends, this core being mounted in the casting member. A first flange is fixedly attached to a first end of the core so as to form a sealed joint. A second flange is fixedly attached to the second end of the core so as to form another sealed joint. The first and second flanges are each coupled by fasteners to their respective ends of the casting.

Heat exchanger with cast housing and method of making the same

A gasket is provided that is suitable for use in connection with a cylinder head. The gasket includes a first outer plate including a compensating portion, a second outer plate including a compensating portion, and a compensating plate positioned between said first and second outer plates. Preferably, at least one of said first and second outer plates includes a bead positioned outside of, and in close proximity to, said compensation portion of said plate. The compensating plate includes a compensating element and an edge portion. In a preferred embodiment, the area between the compensating portions of said first and second outer plates defines a compensating area and said compensating element is positioned within said compensating area. If desired, the gasket may also include a spacer plate.

The invention relates to a metal gasket, in particular a cylinder head gasket, having two beaded metallic cover sheets and having at least one sandwich sheet, which surrounds an opening. The sandwich sheet features a folded edge, that lies in the region of one of the beads of one of the cover sheets. Further, the folded edge is formed in the direction of one of the beads.

Metal gasket with beaded cover plates and sandwich sheet having

A metallic flat gasket, particularly a cylinder head gasket having at least one beaded gasket plate and a support plate surrounds at least one passage opening. On the edge of the gasket plate surrounding the passage opening is shaped a bead, which is held in indirect force closure. To this end the area of the carrier sheet supporting the free leg of the bead is thinner or thicker than the remaining area. It preferably has a topographically freely selected shape and/or different widths along the passage opening circumference. A material reinforcement is obtained in that the carrier sheet is provided with a recess and a metal ring e.g. formed by a fold or flange.
