High-pressure combustion gas generated within the cylinder or the cylinder Cooling water and lubricating oil flowing between the double block and cylinder head leak to the outside. It prevents Also, as a cylinder head gasket like this, multiple pieces of gold are used. Metal cylinder head gaskets made of overlapping metal thin plates have also been known for a long time. Ru.
【0003】 図4は、この様なメタルシリンダヘッドガスケット1の1例を示している。こ のメタルシリンダヘッドガスケット1には、シリンダ頂部の開口形状に合わせた 円形のボア孔2、2、シリンダヘッドをシリンダブロックに固定する為のボルト を挿通する小円孔3、3、冷却水を通す為の水孔4、4、潤滑油を通す為の油孔 が穿設されている。5は各ボア孔2、2の内周縁部に装着した金属薄板製のグロ メットである。0003 FIG. 4 shows an example of such a metal cylinder head gasket 1. child The metal cylinder head gasket 1 has a gasket that matches the opening shape of the top of the cylinder. Circular bore holes 2, 2, bolts for fixing the cylinder head to the cylinder block Small circular holes 3, 3 for passing through, water holes 4, 4 for passing cooling water, oil holes for passing lubricating oil. is drilled. 5 is a metal thin plate groove attached to the inner peripheral edge of each bore hole 2, 2. It's Met.
【0004】 この様なメタルシリンダヘッドガスケット1は、従来から、図5〜6に示す様 に、亜鉛メッキ鋼板、ステンレス鋼板等の金属薄板6〜8を複数枚重ね合わせる 事で構成されている。0004 Conventionally, such a metal cylinder head gasket 1 has been used as shown in FIGS. 5 and 6. , multiple thin metal plates 6 to 8 such as galvanized steel plates and stainless steel plates are stacked on top of each other. It is made up of things.

ところで上述の様に構成されるメタルシリンダヘッドガスケットの場合、水孔 4が図5に示す構造であっても、或は図6に示す構造であっても、シリンダブロ ック9とシリンダヘッド10との間を流れる冷却水は、単に水孔4の内側を流れ るだけで、前記ボア孔2、2周縁部の冷却を必ずしも効率良く行なう事が出来な い。 By the way, in the case of a metal cylinder head gasket configured as described above, the water hole Whether 4 has the structure shown in FIG. 5 or the structure shown in FIG. The cooling water that flows between the hole 9 and the cylinder head 10 simply flows inside the water hole 4. However, it is not always possible to efficiently cool the periphery of the bore holes 2 and 2. stomach.

It is necessary to cool the relevant part, but the conventional metal cylinder head gasket 1 In this case, only the area close to the water hole 4 could be cooled.
【0008】 これに対して、近年に於けるエンジンの高出力化により、ボア孔2、2周縁部 の冷却をより効率良く行なう事が望まれているが、単に水孔4、4の数を増やす 事は、シリンダブロック9上面及びシリンダヘッド10下面の冷却水通路の開口 面積の増大に伴ない、シリンダブロック9やシリンダヘッド10の強度低下を招 く為、採用出来ない。[0008] On the other hand, due to the increase in engine output in recent years, the periphery of the bore holes 2 and 2 It is desired to cool the water more efficiently, but simply increasing the number of water holes 4 and 4 is desirable. The problem is that the cooling water passage openings on the top surface of the cylinder block 9 and the bottom surface of the cylinder head 10 As the area increases, the strength of the cylinder block 9 and cylinder head 10 decreases. Due to this, we cannot hire you.
