  • Gasket for sealing tri-face area
    Patent number: 6659471
    Abstract: A gasket is disclosed, which is adapted for the use in sealing of a tri-face area where a cylinder block, cylinder head and timing-chain housing meet together and come into abutment against one another. With the gasket of this invention, a deposit of bonding agent is applied on an end lug of a solid gasket material to improve the adhesive property and close adherence of the solid gasket material with a fluid gasket material that is filled in the tri-face area. The fluid gasket material charged in the tri-face area is securely fastened to the solid gasket material through the bonding agent. The end lug of the solid gasket material on which the bonding agent is applied is exposed to the tri-face area where both the cylinder head and the cylinder block are cut at their confronting edges to form bevels.
