Patent ID: 8336888

Claim:
A gasket, comprising: a first active layer having a full bead, said full bead being horizontally aligned with, but vertically offset from, an engine liner, said first active layer having an upper surface and a lower surface; a first spacer layer having an upper surface and a lower surface, said first and second surface being substantially parallel to one another from an outer edge of said first spacer layer to radially beyond said engine liner, said first surface being in at least partial contact with said lower surface of said first active layer; an intermediate layer comprising an upper surface, a lower surface, an inner edge, a planar portion and a wave portion extending radially outward from said inner edge to a raised feature on said engine liner, said wave portion comprising a plurality of continuous crests and troughs, wherein said crests contact said lower surface of said first spacer layer, wherein said planar portion extends radially outward from said wave portion; a second spacer layer having an upper surface and a lower surface, wherein at least one of said troughs of said intermediate layer contact said upper surface of said second spacer layer and at least a portion of said lower surface is in contact with said engine liner, wherein said second spacer layer has a bead that receives said raised feature from said engine liner; and wherein said first active layer bead and said intermediate layer plurality of crests and troughs are horizontally aligned with one another but horizontally offset from said bead in said second spacer layer.
