Abstract
A spring back fire ring is provided in a gasket assembly that is used for sealing combustion openings. In addition to the spring back fire ring, the gasket assembly includes a main gasket body and upper and lower gasket layers. The spring back fire ring has first and second ends. The first end is biased upwardly around the periphery of the combustion openings. The second end is positioned proximate to the main gasket body. In one embodiment, the second end is integral with the main gasket body.
Claims22
A gasket assembly for use in sealing mating components in an internal combustion engine, comprising:
- a main gasket body defined by upper and lower surfaces;
- wherein said main gasket body includes at least one combustion opening defined by a peripheral edge;
- and
- a single, separate generally planar spring back fire ring positioned and disposed in each combustion opening;
- wherein said spring back fire ring has a first end that is biased upwardly around the periphery of said combustion opening at an angle in a range of approximately 25-65 degrees and a second end that is positioned proximate to said peripheral edge of said main gasket body and non-integral with said main gasket body.
A gasket assembly for use in sealing mating components in an internal combustion engine, comprising:
- a main gasket body defined by upper and lower surfaces;
- wherein said main gasket body includes at least one combustion opening defined by a peripheral edge;
- an upper gasket layer and a lower gasket layer, each having at least one combustion opening that corresponds generally to the combustion openings formed in said main gasket body;
- wherein said upper gasket layer is positioned on one side of said main gasket body and said lower gasket body is positioned on a side of said main gasket body that is opposite of said upper gasket body;
- and
- a spring back fire ring positioned and disposed in said combustion openings of said upper gasket layer, lower gasket layer, and said main gasket body when said combustion openings of said upper, lower, and main gasket layers are aligned;
- wherein said spring back fire ring has a first end that is biased upwardly around the periphery of said combustion opening and a second end that is positioned proximate to said peripheral edge of said main gasket body, said spring back fire ring further including at least one control bead formed thereon.
A gasket assembly for use in sealing mating components in an internal combustion engine, comprising:
- a main gasket body defined by upper and lower surfaces;
- wherein said main gasket body includes at least one combustion opening defined by a peripheral edge;
- and
- a spring back fire ring positioned and disposed in each combustion opening;
- wherein said spring back fire ring has a first end that is biased upwardly around the periphery of said combustion opening and a second end that is positioned proximate to said peripheral edge of said main gasket body;
- wherein said first end of said spring back fire ring includes a first upwardly extending control bead and a second downwardly extending control bead that are generally opposing and spaced laterally from one another.
