摘要： A cylinder head gasket 1 includes at least two first and second seal plates 11 and 12 in which oil drop holes 4 are perforated, respectively. On the first and second seal plates, half beads 11a and 12a that endlessly surround the oil drop holes and that project in a direction toward each other to be mutually pressed are formed, and the oil drop holes are sealed by these half beads. Outside of the respective half beads, auxiliary beads 11c and 12c that project in a direction toward each other to be mutually pressed are formed. Projection directions of the half beads and the auxiliary beads may be opposite to each other. Since the respective auxiliary beads 11c and 12c give acting forces that press the respective half beads 11a and 12a against a cylinder head or a cylinder block, a better sealing property can be secured as compared with a conventional cylinder head gasket.
摘要翻译：气缸盖垫片1包括至少两个第一密封板11和第二密封板12，在所述第一密封板和第二密封板中分别穿孔有油滴孔4。在第一密封板和第二密封板上形成环绕油滴孔并且沿彼此相向的方向突出以相互挤压的半环11a和12a，并且油滴孔被这些半环密封。在各个半球的外侧，形成有朝相互相向的方向突出并相互压入的辅助突条11c，12c。半珠和辅助珠的投影方向可以彼此相反。由于相应的辅助凸缘11c和12c产生将各个半凸缘11a和12a压靠在气缸盖或气缸体上的作用力，所以与传统的气缸盖垫片相比，可以确保更好的密封性能。

摘要： A cylinder head gasket 1 includes at least one first seal plate 11 held between a cylinder head 2 and a cylinder block 3 having a cylinder bore 4, and the first seal plate 11 includes a combustion chamber hole 13 bored at a position of the cylinder bore 4 and a first full bead 11a surrounding the combustion chamber hole. In the first seal plate 11, a first step 11b U-shaped in section is formed at a position surrounding the combustion chamber hole outside of the first full bead 11a, and a filler 21 is charged in a recessed portion of the first step. Since the cylinder head and the cylinder block can be firmly connected via the step 11b, deformation of the cylinder block by explosion pressure of an engine can be suppressed, and thereby, reduction in sealing performance can be prevented.
摘要翻译：气缸盖垫片1包括至少一个保持在气缸盖2和具有气缸孔4的气缸体3之间的第一密封板11，并且第一密封板11包括在气缸孔的位置处开设的燃烧室孔13 4和围绕燃烧室孔的第一完整焊道11a。在第一密封板11中，在第一全焊道11a的外侧围绕燃烧室孔的位置处形成U形截面的第一台阶11b，并且填充物21填充在第一台阶的凹部中。由于气缸盖和气缸体可以通过台阶11b牢固连接，因此可以抑制气缸体因发动机的爆炸压力而变形，从而可以防止密封性能的降低。

摘要： A cylinder head gasket 1 is sandwiched between a cylinder head 2 and a cylinder block 3 with a cylinder bore 4 and includes a substrate 10 with a combustion chamber hole 14 drilled at a position of the cylinder bore 4, and seal plates 11 to 13, the substrate 10 and the seal plates are stacked on one another. Fixation members 21 and 22 are secured to the substrate around a periphery of the combustion chamber hole. The seal plate includes an engagement hole 23 formed therein and with which the fixation members are engaged. The engagement hole is engaged with the fixation members. The fixation members are sandwiched between the cylinder head and the cylinder block. The cylinder head and the cylinder block can be firmly coupled together via the fixation members. This allows deformation of the cylinder block caused by explosion pressure in an engine to be suppressed. As a result, possible degradation of sealability can be prevented.
