摘要： A cylinder head gasket includes a first gasket base plate at a cylinder head side, a second gasket base plate at a cylinder block side, a shim that adjusts the gasket thickness, and a pressure increasing plate that increases the surface pressure at the side of periphery portions of the cylinders. In the first and second gasket base plates full beads are swollen at the side of periphery portions of cylinders, and half beads are swollen at a site outward of the full beads. The full beads of the first and second gasket base plates are formed so that top portions of the full beads face each other at positions that are opposite to each other in the up-down direction. The shim and the pressure increasing plate are sandwiched between the top portions.

Fixation members 21 and 22 are secured to the substrate around a periphery of the combustion chamber hole. The seal plates include 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.

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.

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： 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包括至少两个第一和第二密封板11和12，其中分别穿有油滴孔4。 在第一密封板和第二密封板上形成有连续地围绕油滴孔并且朝向彼此相互挤压的方向突出的半珠11a和12a，并且油滴孔被这些半珠密封。 在相应的半珠之外，形成相互朝向彼此突出的辅助珠11c和12c。 半珠粒和辅助珠粒的投影方向可以彼此相反。 由于相应的辅助珠11c和12c赋予相应的半珠11a和12a抵靠气缸盖或气缸体的作用力，所以与传统的气缸盖垫圈相比，可以确保更好的密封性能。
