  • Patent number: 8695986
    Abstract: A static cylinder head gasket assembly includes an inner distance layer having an opening extending between opposite planar sides with the opening being configured to register with a cylinder bore of an internal combustion engine. A plurality of inner functional layers overlie each of the opposite sides of the inner distance layer. The inner functional layers have axially aligned, nested annular sealing beads extending about the opening in the distance layer. The gasket assembly further includes a plurality of outer functional layers separate from the inner functional layers. The outer functional layers have annular inner peripheries spaced axially from one another to provide a gap configured to receive at least a portion of the inner distance layer therein. The outer periphery of the inner distance layer is captured axially between the outer functional layers and thus, the inner distance layer is prevented from being disassembled from the outer functional layers.
