    • A metal gasket for an internal combustion engine is formed of at least one metal plate extending substantially throughout an entire area to be sealed. The metal plate includes a hole to be sealed, and a bead projecting outwardly from the metal plate to surround the hole. A concave is formed inside the bead to extend inwardly from an outer surface of the metal plate. A sealing material is disposed in the concave to project outwardly from the outer surface of the metal plate. Thus, even if a foreign material is disposed on the bead, the sealing ability of the gasket is not substantially affected.
    • 用于内燃机的金属垫圈由至少一个金属板形成,该金属板基本上在整个被密封区域上延伸。 金属板包括要被密封的孔和从金属板向外突出以围绕孔的珠。 在胎圈内部形成凹部,从金属板的外表面向内延伸。 密封材料设置在凹部中以从金属板的外表面向外突出。 因此,即使在胎圈上设置异物,垫圈的密封性基本上不受影响。

    • A cylinder head gasket for an internal combustion engine is formed of a first metal plate extending substantially throughout an entire area of the gasket. The metal plate includes a base portion, at least one hole corresponding to a cylinder bore of the engine, a curved portion for defining the at least one hole, and a flange extending from the curved portion to be located above the base portion. A plated layer formed of soft metal is disposed on at least one surface of the base portion, curved portion and flange of the first metal plate facing outwardly of the gasket to thereby form a sealing portion by the plated layer.
    • 用于内燃机的气缸盖衬垫由基本上在垫圈的整个区域延伸的第一金属板形成。 金属板包括基部,与发动机的气缸孔对应的至少一个孔,用于限定至少一个孔的弯曲部分,以及从弯曲部分延伸到位于基部之上的凸缘。 由软金属形成的镀层设置在基部的至少一个表面上,第一金属板的弯曲部分和凸缘面向衬垫的外侧,由此形成由镀层形成的密封部分。
