A steel laminate gasket
摘要:
A steel laminate gasket (A) of the invention is used for an internal combustion engine having at least one hole (Hc) therein. The gasket comprises a first plate (A30) having at least one first hole and a first bead (A30a) situated adjacent to the first hole to surround the same, and a second plate (A31) situated adjacent to the first plate. The second plate is provided with at least one second hole, at least one second bead (A31a) situated adjacent to the second hole to surround the same, and at least one third bead (A31b) surrounding the second bead at a predetermined distance away. When the first and second plates (A30. A31) are assembled together, the first bead (A30a) faces the second plate (A31), and second and third beads (A31a, A31b) face the first plate (A30), wherein the first bead (A30a) is located between the second and third beads. When the gasket is tightened, the first, second and third beads form a plurality of corrugated beads at selected areas around the hole to seal it securely and widely.
