Cylinder head gasket with partial resin coatings |
摘要 |
A cylinder head gasket for an internal combustion engine is formed by a first metal plate extending substantially throughout an entire area to be sealed and having a first hole corresponding to a hole of the engine, and second and third metal plates disposed to sandwich the first plate and having second and third holes formed in the respective second and third plates corresponding to the first hole. First and second beads are formed in the respective second and third plates to extend toward the first metal plate. A first resin coating is deposited on at least one side of the first metal plate at an inner portion relative to the first bead, and a second resin coating is deposited on at least one side of the first metal plate at an outer portion relative to the first bead without extending over an entire surface thereof. The second resin coating has a thickness at most equal to that of the first resin coating. The surface pressure around the hole can be adjusted precisely.
