摘要:
A cylinder head gasket for an internal combustion engine with a cylinder bore and a fluid hole includes a first metal plate (10) having a curved portion around the cylinder bore and a folded portion extending from the curved portion, and a second metal plate (20, 20A) laminated on the first metal plate and having a first full bead (21, 21A) projecting toward the first metal plate. The first full bead is disposed on the folded portion. At least one secondary plate (30, 40, 50) is inserted inside the folded portion.
摘要:
A cylinder head gasket (1, 1A) for an internal combustion engine is formed of first and second metal plates (10, 20) laminated together. The first plate (10) has a first hole, a first bead (11) surrounding the first hole, and an inner portion (10a) extending from an edge of the first hole to an inner side of the first bead. The second plate (20) has a second hole, and a second bead (21) surrounding the second hole and located above the inner portion. When assembled, the first bead faces the second plate and the second bead faces the first plate. A step regulation layer (30) formed of resin is deposited on at least a part of the inner portion (10a) of the first plate such that the second bead (21) is placed on the step regulation layer. The surface pressure for the first bead can be easily adjusted by the step regulation layer.
