Abstract
A cylinder head gasket seals combustion chamber openings with two exterior active sealing layers and a central spacer layer. In web areas between adjacent combustion openings, each opening beginning of the active layers has a land, where a circumferential main stopper is formed with the central spacer layer between the lands. Each active layer further has longitudinal waves formed with the active layer which, when compressed, form a longitudinal support wave stopper(s) in the web areas. Each web area active layer further has a full bead(s) in contact with the central spacer layer. For each exterior layer, in one case, two beads come together to form a single central web area bead that separates two wave stoppers. In another case, the two outer bead portions come together upon entering the central web area while a single wave stopper is formed between the two inner bead portions.
