摘要： A metal gasket with a hole to be sealed includes first and second metal base plates laminated together. The first metal base plate has a first main bead around the hole, and a first outer sub-bead section smaller than the first main bead and provided outside the first main bead. The second metal base plate has a second main bead around the hole, and a second outer sub-bead section smaller than the second main bead and provided outside the second main bead. The second outer sub-bead section abuts against the first outer sub-bead section for sealing.

摘要： A metal gasket for an internal combustion engine includes a first metal plate with a folded portion; a ring member with a sandwiched portion having a sealing bead and an extension portion, with the sandwiched portion being sandwiched in the folded portion to provide a primary sealing portion; a second metal plate laminated to the folded portion of the first metal plate so as to sandwich the extension portion to provide a secondary sealing portion; and a third metal plate sandwiched between the first metal plate and the second metal plate in a portion of the gasket separate from the sandwiched extension portion. In the event that the cylinder head lift becomes greater than the following capability of the sealing bead in the primary sealing portion, the secondary sealing portion provides excellent following capability relative to the lift.

摘要： A metal gasket for sealing multiple cylinder bores includes one or more metal substrates, main sealing beads around each of the cylinder bores, and one or more sub-beads. The main sealing beads include meandering portions located in a sealing portion between the cylinder bores, and the sub-bead is provided between the meandering portions. By placing the sub-bead between the main bead meandering portions, the base portion of the meandering portion and the base portion of the sub-bead squeeze each other. As a result, the lower portion of the meandering portion can be prevented from slipping, and the surface pressure can be partially reinforced. The metal gasket provides an excellent seal in a location where surface pressure is often partially reduced.
摘要翻译：用于密封多个气缸孔的金属垫圈包括一个或多个金属基底，围绕每个气缸孔的主密封珠和一个或多个子珠。主密封珠包括位于气缸孔之间的密封部分中的蜿蜒部分，并且在蜿蜒部分之间设置子珠。通过将子珠放置在主珠粒弯曲部之间，蜿蜒部的基部和副珠的基部彼此挤压。结果，可以防止蜿蜒部分的下部滑动，并且可以部分地增强表面压力。金属垫圈在表面压力通常部分减少的位置提供了极好的密封。

摘要： A metal gasket is formed by a bead plate provided with a continuous bead, and an outer plate partly bent around combustion chamber holes to laminate the metal plates together. The bead has a linear common portion situated in an intermediate area between two cylinder bore holes, curved surrounding portions diverging from the linear common portion near the one second hole to partly surround the cylincder bore and water hole, and a curved linking portion extending between the curved surrounding portions to partly surround the water hole. The water hole is completely surrounded by the parts of the curved surrounding portions and the curved linking portion.

摘要： A metal laminate gasket for an internal combustion engine is formed by a first metal plate having a first hole corresponding to a hole of the engine, and a bore ring and a second metal plate both being disposed under the first metal plate. The bore ring has a second hole corresponding to the first hole, and at least two first engaging members formed around an outer periphery thereof with a predetermined distance away from each other. The second metal plate includes a third hole having a size for receiving the outer periphery of the bore ring, and at least two second engaging members formed around an inner periphery thereof to engage the at least two first engaging member. The first and second engaging members are arranged such that the bore ring can be positioned and retained in the second metal plate in only one position even if the bore ring is positioned upside down.

摘要： A metal laminate gasket of the invention is installed in an internal combustion engine having at least one hole therein. The gasket includes a first metal plate with a base section, and a second metal plate situated above the base section of the first metal plate. The first plate includes a first hole to be sealed, and a flange situated above the base portion around the first hole to form a solid portion. The second plate has a second hole, and an inclined portion around the second hole. The diameter of the second hole is substantially the same as the diameter of the outer edge of the flange. When the first and second plates are assembled, the flange is located inside the second hole. When the gasket is tightened, the flange non-resiliently seals around the hole, and the inclined portion resiliently seals outside the flange.

摘要： A metal gasket of the invention is used for a cylinder head gasket or a pipe connecting gasket. The gasket is basically formed of a single metal plate having a base portion extending substantially throughout an entire area to be sealed, and includes a bead protecting portion extending outwardly from the front surface and a sealing bead adjacent to the bead protecting portion. The bead protecting portion and the sealing bead are formed in the metal plate. The bead protecting portion has no substantial compressibility, but the sealing bead has a compressibility. Thus, when the metal plate is compressed, the bead protecting portion provides a surface pressure without substantial resiliency, and the sealing bead provides a surface pressure with resiliency and is protected from being completely compressed by the bead protecting portion. The gasket can be made thin.
