Abstract: A multilayer gasket for establishing a gas and/or fluid-tight seal between a cylinder head and engine block of an internal combustion engine is provided. The gasket includes a pair of functional layers each presenting a full bead and a half bead. A single-piece stopper with a fold over adjacent the combustion chamber opening is disposed between the function layers. The stopper extends between a fifth edge and a sixth edge, wherein the sixth edge is disposed radially between the full beads and the half beads. The stopper can be cranked or coined in a location disposed between the fold over and the full beads. The stopper can also include a secondary fold over adjacent the sixth edge. A distance layer is optionally disposed between the stopper and one of the functional layers. The distance layer can also be cranked or coined between the fold over and the full beads.

Abstract: A cylinder head gasket including a first functional layer, a second functional layer, a first stopper, and a second stopper is provided. The first functional layer includes a first full bead extending around a combustion chamber opening and axially aligned with a second full bead of the second functional layer. The first stopper extends along the first functional layer between the combustion chamber opening and the first full bead for preventing over-compression of the first full bead. The second stopper extends along the second full bead of the second functional layer for increasing load on the second full bead, reducing head lift, and promoting an even distribution of the load. The second stopper includes a third full bead matching the second full bead of said second functional layer.

Abstract: A cylinder head gasket including at least three functional layers and at least two stoppers is provided. The first functional layer includes a first full bead extending around a combustion chamber opening and axially aligned with a second full bead of the second functional layer. The first stopper extends along the first functional layer between the combustion chamber opening and the first full bead for preventing over-compression of the first full bead. The second stopper is located beneath the second full bead of the second functional layer for increasing load on the second full bead, reducing head lift, and promoting an even distribution of the load. The second stopper is not attached to the second functional layer along and adjacent the second full bead, and thus an air gap is present between the second stopper and the second full bead when the gasket is not compressed.

Abstract: A metal gasket for establishing a seal between a first member and a second member is provided. The metal gasket includes at least one functional layer with an inner periphery which surrounds an opening. The functional layer also has a generally flat portion and an embossment bead with the embossment bead being spaced from the inner periphery and surrounding the opening. The embossment bead extends in a first direction away from the generally flat portion, has an indentation which extends in a second direction opposite of the first direction and has a bead height of greater than 0.15 mm and no greater than 0.30 mm.
