ABSTRACT:
A metal gasket is formed of first, second and third metal plates laminated together. The first metal plate has a first hole, and the second metal plate is situated above the first metal plate and has a second hole. The second hole is greater than the first hole and has a second edge located above the first metal plate. A first bead is formed in at least one of the first and second metal plates to surround the first and second holes. The third metal plate includes a base portion situated above the second metal plate, a curved portion extending from the base portion and situated inside the first and second holes, and a flange extending from the curved portion and situated under the first metal plate. The flange has a third edge located between the first and second edges, so that high surface pressure areas are formed above the flange and the first bead with a low surface pressure area therebetween, by which the gasket can be securely sealed.
