摘要： PROBLEM TO BE SOLVED: To provide a cylinder head gasket allowing to dispose a first bore bead even in an engine having narrow intervals between adjacent cylinder bores, and securing good followability.
SOLUTION: This cylinder head gasket 1 comprises a first gasket substrate 2 having a plurality of combustion chamber bores 4 formed thereon and a second gasket substrate 3. A stepped stopper 2A having a U-shaped cross section and surrounding the outer circumference of each of the combustion chamber bores 4, and a first bore bead 2B surrounding the outer circumference of a stepped stopper are formed on the first gasket substrate. A second bore bead 3B superposing with the first bore bead is formed on the second gasket substrate. The first bore bead and the second bore bead are gathered into one line, respectively, in an area where the adjacent combustion chamber bores are close to each other. The width of the first bore bead is set smaller than the width of the second bore bead. The height of the first bore bead is set lower than the height of the second bore bead. Thus, the first bore bead can be arranged even in the area where the adjacent combustion chamber bores are close to each other, and good followability can be secured.

摘要： PROBLEM TO BE SOLVED: To improve sealing performance of a metal gasket 1 by obtaining uniformity, as compared with in the past of a load applied to the roof surface of an annular protrusion 11 by each of the constitution. SOLUTION: A metal-made gasket base board 2 is formed with a bead part 7 and an annular protrusion 11 in a side of a combustion chamber hole 3 from the bead part 7. The shape of the annular protrusion 11, as a first constitution, makes a wall surface height t2 of an outer sidewall surface 11B smaller than a wall surface height t1 of an inner sidewall surface 11A. As a second constitution, an outer side base board radius of curvature r1b is set larger than an inner side base board radius of curvature r1a, and an outer side roof surface radius of curvature r2b is set larger than an inner side roof surface radius of curvature r2a. In addition, as a third constitution, an inner side angle θ2 of the outer sidewall surface 11B is made smaller than an inner side angle θ1 of the inner sidewall surface 11A. These first to third constitutions may be used independently or with the two kinds combined.

摘要： PROBLEM TO BE SOLVED: To simplify coating work by applying a liquid packing 23 to the lower surface of a shield member 22 only so as to reduce manufacturing costs for a cylinder head gasket 6. SOLUTION: In a cylinder head gasket 6 an engagement hole 21 is formed at the boundary section 18 between a cylinder block 3 and a case 4. A rubber shield member 22 is fit on the engagement hole 21. A plurality of communicating holes 22a are vertically punched on the shield member 22. A liquid packing 23 is applied to the lower surface of the shield member 22 only or also to the upper surface of the member 22 via the communicating hole 22a when holding the cylinder head gasket 6 between a cylinder head 2, and the cylinder block 3 and the case 4.

摘要： PURPOSE:To improve the sealing function of an outer peripheral bead and improve reliability by setting the spring constant of a bead formed at the outer peripheral edge part to be relatively smaller than that at the separated part, at the part where the bead approaches within a prescribed distance. CONSTITUTION:The height H of an outer peripheral bead 18 is set lower than the height H2 of other bead 17 at the part where other bead 17 in proximity exists, and set higher than the height H2 at the part where other bead 17 is close, at the part where other bead 17 in proximity does not exist, and the spring constant of the outer peripheral bead 18 is set small at the part where other bead 17 in proximity exists, and set large at the part where other bead 17 does not exist. Since the spring constant of the outer peripheral bead 18 can be varied according to the part where other bead 17 is close or not, the surface pressure due to the outer peripheral bead 18 can be made nearly equal at all parts independently of the existence of other bead 17 in proximity, and the sealing function of the outer peripheral bead 18 can be improved in comparison with that in the conventional.

摘要： PURPOSE:To prevent the damage of a joint face due to a bead and to ensure stable sealing ability on the whole of a metallic gasket by increasing the thickness of a seal film on the surface on the protrusion part side of a bead to a value higher than that of a seal film on the surface on the recessed part side of the bead. CONSTITUTION:First seal films 16a and 16b of a vulcanized rubber layer formed of vulcanized fluorine rubber are formed on both surfaces of a base plate 10. The first seal films 16a and 16b are a seal film adhered on the surface on the protrusion part 15a side of a bead 15 and the surface on the recessed part 15b side thereof, and a thickness t1a of the surface on the protrusion part 15a side of the bead 15 is increased to a value higher than a thickness t1a of the back thereof. Second seal films 17a and 17b of a non-vulcanized or unvulcanized rubber layer formed on both surfaces of the base plate 10 are adhered to the first seal films 16a and 16b, respectively. A thickness t2a of the surface on the protrusion part 15a side of the bead 15 of the second seal films 17a and 17b is increased to a value higher than a thickness t2b of the back thereof. This constitution prevents the top surface of the protrusion part of the bead from being exposed to damage a joint face and ensures stable sealing ability.

摘要： PURPOSE:To secure a stable sealability without being affected by a differential thermal expansion, etc., by welding a shim ring substantially continuously with a substrate along the whole circumference at least close to an inner edge. CONSTITUTION:A metal gasket 1 has a resilient metal plate, that is a substrate 10 of stainless steel, for example, a combustion chamber hole 11, etc., are bored in this substrate 10, and a bead 15, and inclined parts 16-18 are formed in it. A circular metal plate, or a spacer of stainless steel, or a so-called shim ring 20, for example, is fixed to the bead 15 on the side of a protruding part 15. The shim ring 20 is disposed to put its inner edge almost along the inner edge of an aperture end part 10a, and laser welding is performed close to the inner edge. A weld line 21 which is substantially continuous along the whole circumference of the inner edge of the circular shim ring 20 is therefore formed. Penetration of pressure fluid between the shim ring and the substrate can thus be prevented, and a stable sealability can be secured.
