发明名称 Metal laminate gasket with wide and narrow flange portions
摘要 <p>A metal laminate gasket of the invention is used for an internal combustion engine having a sealing hole and a plurality of bolt holes situated around the sealing hole. The gasket is formed of first and second metal plates having holes corresponding to the sealing hole and the bolt holes of the engine. The second metal plate includes a base portion, a curved portion extending from the base portion to define one hole therein, and located inside one hole in the first plate, and a flange extending from the curved portion and disposed over the first plate. The flange has a plurality of wide flange portions and narrow flange portions alternately arranged to each other such that the wide flange portions are located near the bolt holes to support high tightening pressures applied thereto. A bead may be formed on one or both of the first and second plates outside the flange. The bead may have wide and narrow portions to provide equal surface pressures as a whole. &lt;IMAGE&gt;</p>
