摘要： This metal gasket comprises a bead base plate with first beads and a sub-plate stacked on the bead base plate. The sub-plate is made of a thick metal plate and formed with second and third beads and stepped portions. The second beads, the third beads and the stepped portions combine to form triple seal lines, which improve the sealing function. The sub-plate is formed with the second beads opposing the first beads of the bead base plate, with the high third beads formed inside the second beads around the holes and with the stepped portions formed outside the second beads around the holes. The third beads prevent ingress of burning gases to the first beads and also serve as a stopper to prevent the first beads from being flattened completely. The third beads therefore can add durability to the sealing function realized by the first and second beads, enhancing the sealing performance of the first and second beads and reliably preventing burning gases from escaping between the opposing surfaces.

摘要翻译： 该金属垫圈包括具有第一珠的胎圈基板和堆叠在胎圈基板上的子板。 子板由厚金属板制成并形成有第二和第三珠和阶梯部分。 第二珠，第三珠和阶梯部分结合形成三重密封线，这提高了密封功能。 子板形成有与胎圈基板的第一珠相对的第二珠，高的第三珠形成在第二珠周围的孔周围，并且阶梯部形成在第二珠周围的孔周围。 第三珠粒防止燃烧气体进入第一珠粒，并且还用作塞子以防止第一珠粒完全变平。 因此，第三珠可以增加由第一和第二珠实现的密封功能的耐久性，增强第一和第二珠的密封性能，并可靠地防止燃烧气体在相对表面之间逸出。

摘要： A gasket is disclosed, which is adapted for the use in sealing of a tri-face area where a cylinder block, cylinder head and timing-chain housing meet together and come into abutment against one another. With the gasket of this invention, a deposit of bonding agent is applied on an end lug of a solid gasket material to improve the adhesive property and close adherence of the solid gasket material with a fluid gasket material that is filled in the tri-face area. The fluid gasket material charged in the tri-face area is securely fastened to the solid gasket material through the bonding agent. The end lug of the solid gasket material on which the bonding agent is applied is exposed to the tri-face area where both the cylinder head and the cylinder block are cut at their confronting edges to form bevels.

摘要： This metal gasket is formed by interposing a shim member between a pair of elastic metal plates, and fixing the shim member and one of the elastic metal plate to each other at the portions thereof which are opposed to a water jacket, whereby the function of the shim member is secured with the fixed portions and opposed surfaces not interfering with each other. The shim member comprises a shim member body corresponding to an end surface of a cylinder body of a cylinder block, and projecting portions integral with said shim member body and extending therefrom to a position opposed to the water jacket. The fixing portions at which the shim member and one elastic metal plate are fixed to each other by crimping are positioned on the projecting portions extending to positions opposed to the water jacket. Therefore, when the metal gasket is tightened between the cylinder block and a cylinder head, the fixed portions do not interfere with the opposed surfaces thereof including end surfaces, and the sealing function of the metal gasket is not spoiled.

摘要翻译： 该金属垫片是通过在一对弹性金属板之间插入垫片构件而形成的，并且将垫片构件和弹性金属板中的一个彼此相对地设置在与水套相对的部分，由此， 垫片构件固定有固定部分和相对的表面，彼此不干涉。 垫片构件包括与气缸体的气缸体的端面对应的垫片构件，以及与所述垫片构件主体一体的突出部分，并从其延伸到与水套相对的位置。 垫片构件和一个弹性金属板通过卷边彼此固定的固定部分位于延伸到与水套相对的位置的突出部分上。 因此，当金属垫圈被紧固在气缸体和气缸盖之间时，固定部分不会与包括端面的相对表面干涉，并且不会损坏金属垫圈的密封功能。

摘要： This metal gasket comprises a pair of beaded metal plates formed of elastic metal plates having beads extending along the circumferences of bore holes, and adapted to seal bore seal portions, and one outer circumferential metal plate formed of an elastic metal plate adapted to seal outer circumferential seal portions other than the bore seal portions. The beaded metal plates and outer circumferential metal plate have different sealing performance, and are adapted to seal the bore seal portions and outer circumferential seal portions respectively, these two types of metal plates being formed out of different materials, whereby the gasket manufacturing cost is reduced. A pair of beaded metal plates are provided with beads extending along the circumferences of the bore holes with the projecting portions thereof opposed to each other. Since the thickness of the single outer circumferential metal plate is set larger than that of each of the beaded metal plate and smaller than a total thickness of the two beaded metal plates, the surface pressure of the bore hole-surrounding regions can be set high.

摘要翻译： 该金属垫圈包括一对由弹性金属板形成的串珠金属板，该金属板具有沿着孔眼的周边延伸的珠，并且适于密封孔密封部分，以及由弹性金属板形成的一个外周金属板，该弹性金属板适于密封外周 密封部分以外的密封部分。 串珠金属板和外周金属板具有不同的密封性能，并且分别适用于密封孔密封部分和外周密封部分，这两种类型的金属板由不同材料形成，从而减少了垫片制造成本 。 一对串珠金属板设置有沿着孔的周边延伸的珠，其凸出部分彼此相对。 由于将单个外周金属板的厚度设定为大于串联金属板的厚度，并且小于两个串联金属板的总厚度，所以可以将钻孔周围区域的表面压力设定得较高。
