  • Patent number: 9068654
    Abstract: A gasket held between opposite flange joint surfaces with a bolt includes a combination of a complex material with a rubber material formed on one or both sides of a steel plate, the complex material having a convex or waveform bead, and a circular metal plate arranged at a bolt portion with a through-hole where a shank of the bolt penetrates and a bearing corresponding portion that corresponds to a bearing of the bolt around the through-hole. The gasket is configured to have the thickness (H3) of the bead provided to the complex material greater than the thickness (H2) of the circular metal plate that is equal to or greater than the thickness (H1) of the complex material. This structure provides a gasket indicating good sealing properties under such circumstances that a flange has low stiffness, a tightening load is reduced, and the distance between bolts is expanded.

  • Publication number: 20140123849
    Abstract: A cylinder head gasket includes two main members on two sides, and middle members sandwiched therebetween. The middle members are composed of a first middle member and a second middle member that is separated and distinct therefrom. The first middle member is a metal plate that has cylinder hole rim portions encircling cylinder holes to a particular width, with beads surrounding the cylinder holes being formed in the cylinder hole rim portions. The metal plate either forms separated items, one at each cylinder hole, or else forms an integrated item connected between the cylinder holes. The second middle member is a metal plate that is disposed on the outside of the first middle member and has oil holes and bolt holes. The thickness of the first middle member is greater than that of the second middle member.
