のである。[Detailed explanation of the invention] [Industrial application field] This invention relates to a metal laminated gasket.
More specifically, it is a metal laminated type gasket that has improved sealing performance by configuring the gasket body disposed around the periphery of the liquid distribution hole and the combustion chamber hole to correspond to areas with high and low surface pressures. It is related to.

Conventionally, a metal laminated gasket 1 interposed between a cylinder head and a cylinder block, as shown in FIG. A plurality of liquid circulation holes 3, 4 and combustion chamber holes 12 are formed corresponding to the passages and lubricating oil passages.

る。 By the way, the conventional metal laminated gasket 1 has metal plates 7, as shown in FIG.
The terminal parts 7a, 8a of 8 are each formed in a U-shape, and a metal plate 6 with a bead part 6a formed therein, two intermediate plates 10a, 10b, an upper plate 11, and a lower plate 9 are interposed. The metal laminated gasket 1 thus constructed is used by being interposed between a cylinder head and a cylinder block.

間で均一な締め付け力により固定した場合、燃焼
室穴１２を流通するガス圧力は、前記液体流通穴
３（冷却通路）を流通する冷却水の圧力よりも高
いため、例えば締め付け力が弱いエンジンにあつ
ては、シリンダボア周縁部のシール性が悪くなる
と言う問題があつた。 However, when such a conventional metal laminated gasket 1 is fixed between the cylinder head and the cylinder block with a uniform tightening force, the gas pressure flowing through the combustion chamber hole 12 is lower than the liquid flow hole 3 (cooling passage). ) is higher than the pressure of the cooling water flowing through the cylinder bore, so for example in engines where the tightening force is weak, there is a problem in that the sealing performance around the cylinder bore deteriorates.
そこで、前記高い面圧を必要とする燃焼室用の
ビードの高さを、低い面圧でシールすることがで
きる液体流通穴用のビードより高く形成し、また

考案がある。 Therefore, the height of the bead for the combustion chamber, which requires high surface pressure, is made higher than that of the bead for the liquid flow hole, which can be sealed with low surface pressure, and the bead is made to have a hardness equal to or lower than that of the bead plate. There is a device proposed in Japanese Utility Model Application Publication No. 122558/1983 that uses a sub-plate consisting of a plate of .

め付け力をシールする部分に集中させる手段を開
示している。 According to the description in this publication, when implementing this prior art, the sub-plate needs to have a complicated shape and thickness, and if necessary, a bead is formed in a loop shape around the hole to be sealed. When tightening the gasket, make the loop meandering instead of making it circular to create a trajectory that corresponds to the pressure resistance, or make holes in the laminate plate in places that do not affect the seal and tighten the gasket in areas where force would be wasted. Discloses a means for punching holes in the plate to concentrate the tightening force on the area to be sealed.

面圧を生じるビードと低い面圧を生じるビードと

圧の変化に限度がある。したがつて前記のとお
り、かなり複雑な形状の副板を必要とするなどガ
スケツトの構造が複雑となるという欠点がある。 However, in the case of the above-mentioned prior art, since a bead that generates a high surface pressure and a bead that generates a low surface pressure are provided on the same bead plate, there is a limit to the change in surface pressure. Therefore, as mentioned above, there is a drawback that the structure of the gasket becomes complicated, such as requiring a sub-plate with a rather complicated shape.

及的に薄くするように作用する。The structure of the metal laminated gasket in which beads that provide high surface pressure and beads that provide low surface pressure are formed on separate bead plates makes it easier to achieve the required bead characteristics. Furthermore, when stacking the two bead plates, the configuration in which the top of each bead is placed on the side of the other bead plate facilitates gasket assembly, and also reduces the thickness of the laminate as much as possible. It acts to make it thinner.

The 6" bead portions 6c and 6b are made by increasing the bead height h1 of the bead portion 6b located on the combustion chamber hole 12 side, increasing the thickness l1 of the metal plate 6' on which the bead is formed, and also increasing the thickness l1 of the metal plate 6' on which the bead is formed. The bead portion 6c located on the liquid circulation hole 3 side is formed by reducing the bead height h2 and reducing the thickness l2 of the metal plate 6'' on which the bead is formed.

る。 By configuring the metal laminated gasket 1 as described above, when the metal laminated gasket 1 is interposed between the cylinder block and the cylinder head and is tightened and fixed with an even tightening force, the combustion chamber hole 2 through which high-pressure fluid passes is formed. The clamping force at the peripheral edge becomes stronger, and the clamping force at the periphery of the liquid circulation hole 3 of the cooling passage through which relatively low-pressure fluid passes is weakened, and as a result, the metal laminated gasket 1 resists fluid pressure.
This allows for uniform sealing throughout.
