【考案の詳細な説明】
シリンダー孔を取り囲む第一ビードおよび水、
油等の液体孔を取り囲む第二ビードを設けた金属
単体形シリンダヘツドガスケツトは公知である。[Detailed description of the invention] A first bead surrounding the cylinder hole and water;
Solid metal cylinder head gaskets are known which are provided with a second bead surrounding a hole for a liquid such as oil.
本考案は、この公知の金属単体形ガスケツトの
改良に係り、シール性能を尚一層向上させた製品
を提供することを目的として案出したものであ
る。 The present invention has been devised for the purpose of improving this known single metal gasket and providing a product with further improved sealing performance.
すなわち、シリンダヘツドガスケツトは、内圧
の高い燃焼ガスのシールのためにシリンダー孔部
にガスケツトの締付け荷重の大部分を集中させ、
残りの荷重を水、油等のシール部に分散させる面
圧調整が重要である。 In other words, the cylinder head gasket concentrates most of the gasket's tightening load on the cylinder hole in order to seal the combustion gas with high internal pressure.
It is important to adjust the surface pressure to distribute the remaining load to the water, oil, etc. seals.
本考案はこの面圧調整をビードによつて行うよ
うにしてシール性能の優れた金属単体形シリンダ
ヘツドガスケツトを提供できるものである。 The present invention is capable of providing a single-metal cylinder head gasket with excellent sealing performance by adjusting the surface pressure using a bead.

一ビード３と第二ビード４は高さを互いに同じく
し、ガスケツト本体Ａに対するビードの傾斜角度
を、第二ビード４より第一ビード３側を大きくし
てある。 The drawing shows an embodiment of a single metal cylinder head gasket according to the present invention.The gasket of the embodiment is press-formed from a steel plate.A cylinder hole 1 and a liquid hole 2 are formed in the gasket body A. The first bead 3 surrounding the cylinder hole 1 is provided in the first part of the hole, and the second bead 4 surrounding the liquid hole 2 is provided in the second part of the liquid hole. The angles of inclination of the beads with respect to the gasket body A are made larger on the first bead 3 side than on the second bead 4.
なお、液体孔２には、水孔、油孔およびプツシ
ユロツド孔があるが、一般的には水孔と油孔をそ
れぞれ取り囲むビードは、前記の傾斜角度を同じ
にして良く、これらはプツシユロツド孔より大き
な角度で構成すると良い。 The liquid hole 2 has a water hole, an oil hole, and a push rod hole, but generally the beads surrounding the water hole and the oil hole may have the same inclination angle as described above, and these are more inclined than the push rod hole. It is best to compose it at a large angle.
しかして、第３図はビードの圧縮特性曲線図を
示すが、該図中実線がシリンダー孔ビード３を、
また、点線が液体孔ビード４を示している。 Therefore, FIG. 3 shows a compression characteristic curve diagram of the bead, and the solid line in the figure indicates the cylinder hole bead 3.
Further, dotted lines indicate liquid hole beads 4.
この図で明らかな通り、圧縮率が同一であれ
ば、傾斜角度の大きいビードすなわちシリンダー
孔ビードに液体孔ビードと較べ大きな面圧が発生
することが解る。 As is clear from this figure, if the compression ratio is the same, a larger surface pressure is generated in the bead with a larger inclination angle, that is, in the cylinder hole bead, than in the liquid hole bead.
本考案は前記の通りの構成によつて、シリンダ
ー孔周りに大きな面圧が発生し、ガスシールを確
実に行える単体形ガスケツトを提供できるのであ
る。 With the above-described configuration, the present invention can provide a single-piece gasket that generates a large surface pressure around the cylinder hole and ensures gas sealing.
