본 고안은 실린더헤드용 금속적층형 가스킷에 관한 것이다.The present invention relates to a metal laminated gasket for a cylinder head.

종래에, 가스킷본체를 구성하는 상판 등에 비이드(bead)를 설치하여 시일면압을 확보하도록 한 실린더헤드용 금속적층형 가스킷이 공지되어 있다.Background Art Conventionally, metal laminated gaskets for cylinder heads are known in which a bead is provided on a top plate constituting the gasket body to secure a seal surface pressure.

그러나, 종래에는 비이드를 실린더구멍을 둘러싸도록 설치하여 실린더구멍에 대한 시일면압의 확보에 주력한 것이 대부분으로서, 실린더구멍과 동일한 실린더헤드 가스킷의 피시일구멍인 액체구멍과의 상대적인 시일면압의 확보를 비이드로 구성한 것은 없다.However, in the past, the beads are arranged so as to surround the cylinder holes, and most of them have focused on securing the seal surface pressure to the cylinder hole. Therefore, the relative seal surface pressure to the liquid hole which is the seal hole of the cylinder head gasket same as the cylinder hole Is not composed of beads.

따라서, 종래에는 액체구멍부에 가스킷본체와 별개체인 고무링을 끼워넣어서 액체구멍의 시일면압을 확보할 수 있도록 하고 있지만, 고무링의 별개체이므로, 제작고정상 고무링을 끼워넣는 작업공정을 필요로 하여 번잡할 뿐아니라, 그 작업공정을 실수로 누락시키는 등의 오작업이 생길 우려도 있다.Therefore, in the related art, a rubber ring, which is separate from the gasket body, is inserted into the liquid hole to secure the seal surface pressure of the liquid hole. However, since the rubber ring is a separate body, a work step of inserting a fixed rubber ring is required. Not only is it troublesome, but there is also a risk of misoperation such as accidental omission of the work process.

본 고안은 전기한 종래예의 결점을 제거해서, 실린더구멍과 액체구멍과의 상대적인 시일면압을 확보한 실린더헤드용 금속적층형 가스킷을 제공하는 것을 목적으로 하여 고안된 것이다.This invention is devised for the purpose of providing the metal laminated gasket for a cylinder head which eliminated the fault of the prior art mentioned above, and ensuring the relative sealing surface pressure of a cylinder hole and a liquid hole.

본 고안은 전기한 목적을 달성하기 위해서, 상판, 하판 및 중간판으로 구성된 가스킷본체의 상판 또는 하판에 실린더구멍을 둘러싸는 제1비이드를 설치하고, 상판 또는 하판을 되접어 설치한 실린더구멍의 되접음부 또는 그로밋(grommet)이라고 불리는 단면 U자형상의 원형고리내에 전기한 제1비이드를 배설하고, 실린더구멍의 되접음부 또는 원형고리에 겹쳐지지 않도록 상판과 하판과의 사이에 개재시킨 전기한 중간판의 상하 양면에 피막층을 설치하고, 이 중간판 또는 상하판에 액체구멍을 둘러싸는 제2비이드 설치한 구성으로 한 것이다.The present invention, in order to achieve the above object, the first bead surrounding the cylinder hole is provided on the upper plate or the lower plate of the gasket body consisting of the upper plate, lower plate and intermediate plate, and the upper plate or lower plate of the cylinder hole Electricity interposed between the upper plate and the lower plate so as not to overlap the refolded portion or the circular ring of the cylinder hole by disposing the first bead in the circular U-shaped circular ring called the retracted portion or grommet. The coating layer is provided on both upper and lower surfaces of one intermediate plate, and the second bead surrounding the liquid hole is provided on the intermediate plate or upper and lower plates.

[실시예]EXAMPLE

도면은 본고안에 관한 실린더헤드용 금속적층형 가스켓트의 한가지 실시예를 나타내고 있는데, 부호(A)는 가스킷본체로서, 본체(A)는 상판(1)과 하판(2) 및 중간판(3)등 3장의 금속판으로 구성되어 있다. 부호(4)는 중간판(3)의 상하 양면에 설치한 피막층으로서, NBR고무, 실리콘고무, 불소고무 혹은 합성수지가 사용된다.The figure shows one embodiment of the metal laminated gasket for the cylinder head according to the present invention, where A is the gasket body, and the main body A is the upper plate 1, the lower plate 2, the intermediate plate 3, and the like. It consists of three metal plates. Reference numeral 4 is a coating layer provided on the upper and lower surfaces of the intermediate plate 3, and NBR rubber, silicone rubber, fluorine rubber or synthetic resin is used.

부호(5)는 실린더구멍, 부호(6)는 그 실린더구멍을 둘러싸는 제1비이드, 부호(7)는 액체구멍, 부호(8)는 그 액체구멍(7)을 둘러싸는 제2비이드이다.5 denotes a cylinder hole, 6 denotes a first bead surrounding the cylinder hole, 7 denotes a liquid hole, and 8 denotes a second bead that surrounds the liquid hole 7 to be.

[제1실시예][First Embodiment]

제1도는 제1실시예의 일부를 절제한 평면도이고, 제2도는 제Ⅰ도의 Ⅰ-Ⅰ′선 단면도이다.FIG. 1 is a plan view cut out of a part of the first embodiment, and FIG. 2 is a cross-sectional view taken along the line II 'of FIG.

이 제1실시예는, 하판(2)을 상판(1)쪽으로 되접어 꺾어 되접음부(9)를 설치하고, 그 되접음부(9)에 의하여 실린더구멍(5)을 구성함과 아울러, 되접음부(9)내에 상판(1)에 설치한 제1비이드(6)를 배설해서, 되접음부(9)에 겹쳐지지 않도록 하여 중간판(3)을 상판(1)과 하판(2)사이에 개재시키고, 중간판(3)에는 액체구멍(7)을 둘러싸는 제2비이드(8)를 설치한 것이다.In the first embodiment, the lower plate 2 is folded back toward the upper plate 1 to provide the folded portion 9, and the cylinder portion 5 is formed by the folded portion 9, The intermediate plate 3 is arranged on the upper plate 1 and the lower plate 2 so that the first bead 6 provided on the upper plate 1 is disposed in the retracted portion 9 so as not to overlap the refolded portion 9. The intermediate plate 3 is provided with a second bead 8 surrounding the liquid hole 7.

[제2실시예]Second Embodiment

제2실시예는 제3도에 나타낸다.The second embodiment is shown in FIG.

제2실시예는, 상판(1)과 하판(2)에 액체구멍(7)을 둘러싸는 제2비이드(8)(8)을 설치하고, 각 제2비이드(8)(8)을 중간판(3)을 개재시켜 서로 대향시켜서 구성한 것으로서, 그 외는 제1실시예와 동일하다.In the second embodiment, the second beads 8 and 8 surrounding the liquid holes 7 are provided in the upper plate 1 and the lower plate 2, and each of the second beads 8 and 8 is disposed. It is comprised so that it may oppose each other through the intermediate plate 3, and others are the same as that of 1st Example.

[제3실시예]Third Embodiment

제4도에 나타내는 제3실시예는, 상판(1)을 하판(2)쪽으로 되접어 꺽어서 되접음부(9)를 설치하고, 이 되접음부(9)내에 하판(2)에 설치한 제1비이드(6)를 설치한 것으로서, 그외는 제1실시예와 동일하다.In the third embodiment shown in FIG. 4, the upper plate 1 is folded back to the lower plate 2 so that the folded portion 9 is provided, and the lower plate 2 is provided on the lower plate 2 in the folded portion 9. The first bead 6 is provided, except for the same as in the first embodiment.

[제4실시예]Fourth Embodiment

제5도에 나타내는 제4실시예는, 제1실시예 내지 제3실시예의 되접음부(9) 대신에 그로밋이라고 불리는 단면U자형상의 원형고리(10)를 사용하여 실린더구멍(5)을 구성시키고, 그 원형고리(10)내에 하판(2)과 상판(1)에 설치한 제1비이두(6)를 설치한 것으로서, 그 외는 제1실시예와 동일하다.In the fourth embodiment shown in Fig. 5, the cylinder hole 5 is formed by using a circular U-shaped circular ring 10 called a grommet instead of the refolding portion 9 of the first to third embodiments. In this circular ring 10, the lower nap 2 and the first nasal gland 6 provided on the upper plate 1 are provided, except for the same as in the first embodiment.

[기타실시예][Other Embodiments]

각 실시예의 비이드는 도시한 형상에 한정할 필요는 없다.The beads in each embodiment need not be limited to the shape shown.

그러나, 제2비이드(8)보다 제1비이드(6)를 강하게 한 쪽이(제3 및 제4실시예는 도시하고 있음.) 액체구멍(7)보다 큰 시일면압을 필요로 하는 실린더구멍(5)에 대해서는 양호하다.However, the one in which the first bead 6 is made stronger than the second bead 8 (the third and fourth embodiments are shown) requires a seal surface pressure larger than the liquid hole 7. It is good about the hole 5.

따라서, 제1비이드(6)를 설치한 상판 또는 하판을 두껍게 구성하여도 좋다.Therefore, you may comprise the upper board or lower board which installed the 1st bead 6 thick.

본고안은 전기한 바와같이 구성이므로, 고무링을 필요로 하지 않으며, 제1비이드와 제2비이드의 크기의 관계를 적절히 설정하거나 또는 본체를 구성하는 상판 등의 두께 및 소재를 적절히 선택하는 것에 의해서, 실린더구멍과 액체구멍의 상대적인 시일면압을 확보한 실린더헤드용 금속적층형 가스킷을 제공할 수 있다.Since this paper is configured as described above, it does not require a rubber ring, and appropriately sets the relationship between the size of the first bead and the second bead or appropriately selects the thickness and material of the top plate constituting the main body. The metal laminated gasket for cylinder head which can ensure relative sealing surface pressure of a cylinder hole and a liquid hole by this can be provided.

또, 중간판에 설치한 피막층은, 중간판이 되접음부 또는 단면 U자형상의 원형고리내에 설치되어 있지 않으므로 열에 의한 열화(劣火)가 발생되지 않고, 그 피막층이 상판과 하판의 사이에 개재되어 제2비이드의 시일효과를 한층 증대시켜서 액체구멍을 시일할 수 있다.In addition, since the intermediate | middle plate is not installed in a folding part or a U-shaped circular ring of a cross-section, the coating layer provided in an intermediate plate does not produce deterioration by heat, and the coating layer is interposed between the upper plate and the lower plate. The sealing effect of the second bead can be further increased to seal the liquid hole.
