  • Patent number: 8556272
    Abstract: A multilayer metal static cylinder head gasket for establishing a gas/fluid-tight seal between a cylinder head and an engine block includes a pair of functional layers having openings configured to register with a combustion chamber and annular seal beads configured to form a seal about the openings. The gasket further includes a primary compression limiter formed of a separate piece of material from the functional layers. The primary compression limiter extends at least partially about the openings to facilitate inhibiting the seal beads from being fully flattened between the cylinder head and the engine block. The pair of functional layers have nested protrusions forming a secondary compression limiter spaced radially outwardly from the primary compression limiter to further inhibit the seal beads from being fully flattened between the cylinder head and the engine block.
