发明名称 Metal gasket with a bead surrounding bolt and oil holes
摘要 <p>A metal gasket for an internal combustion engine of the invention is formed of a metal plate, which includes an outer periphery for defining the metal gasket, at least one cylinder bore, a bolt hole, and an oil hole situated between the bolt hole and the outer periphery. A bead is integrally formed with the metal plate to surround only the bolt hole and the oil hole. The bead is formed of two side walls and a center portion between the two side walls, and has a first portion close to the bolt hole and a second portion close to the oil hole. The width of the center portion at the first portion is smaller than that at the second portion and a standing angle of the side walls relative to the metal plate other than the bead at the first portion is smaller than that at the second portion. The bead can provide an equal surface pressure throughout the entire length thereof. &lt;IMAGE&gt;</p>
