Abstract: A gasket for an internal-combustion engine is designed to seal between an engine block and a cover of the internal-combustion engine. The gasket includes a plurality of members that are metal and a layer of elastomeric material on the members. The elastomeric layer includes joints between the members. The joints allow the gasket to flex to accommodate potential variation in sealing surface of the engine block without bending of the members.

Abstract: A multi-layer metal gasket includes a first functional layer and a second functional layer. A bore and a fastener hole extend through the first and second functional layers. The first functional layer has a first embossment protruding toward the second functional layer and the second functional layer has a second embossment protruding toward the first functional layer. The first embossment and the second embossment each encircle the bore. An intermediate layer is between the first and second functional layers. The intermediate layer extends between the first embossment and the second embossment and extends from the first and second embossments to the fastener hole. A spacer layer is between the intermediate layer and the first functional layer. The spacer layer has an inner edge defining a hole through the spacer layer. The inner edge encircles the first embossment. The spacer layer extends from the inner edge to the fastener hole.

Abstract: Processes for making press-in-place (PIP) gaskets. Representative components with gasket cavities (grooves) are prepared and the cavities are filled with a curable molding material. Once the molded gaskets are hardened, they are removed from the cavities. The molded sample gaskets are then measured, preferably by a laser scanner, and drawings are prepared based on the measurement data. Appropriate tooling is then created and the gaskets are produced.
