摘要:
A metal gasket (G) for an internal combustion engine is formed of at least one metal plate (10) for constituting the metal gasket (G). The metal plate (10) includes a hole (HC) and a bead formed (11,11') around the hole (HC) for sealing the same. A thermal sprayed layer (15,15',15",16) is formed integrally on and/or under the bead (11,11',12) to locally increase the surface pressure of the bead when the bead is compressed. Thus, the surface pressure of the bead (11,11',12) can be adjusted individually as desired.
摘要:
A metal gasket of the invention is used for an internal combustion engine. The gasket is formed of at least one metal plate for constituting the metal gasket. The gasket includes at least one bolt hole, and a bead having a main portion extending toward the bolt hole and an end portion located near the bolt hole. The end portion extending from the main portion changes a direction to incline in a direction away from the bolt hole. Accordingly, the end portion can be easily compressed when a bolt passing through the bolt hole is tightened. The plate with the bead may be combined with other plates to form a metal laminate gasket.
摘要:
A metal laminate gasket of the invention is engaged with an engaging projection of an engine part for immovably locating the gasket on the engine part. The gasket is basically formed of first and second metal plates laminating together. The first plate includes at least one first hole and at least one first engaging portion extending into the first hole. The second plate is situated above and connected to the first plate. The second plate includes at least one second hole and at least one second engaging portion extending into the second hole. When the gasket is urged against the engine part, the vertically spaced first and second engaging portions deform and engage the engaging projection to thereby prevent the gasket from easily disengaging from the engaging projection.
