Abstract
A gasket may have at least one metallic layer with at least one combustion gas through-opening and at least one fastener through-opening. The fastener through-opening may be at least partially circumferentially bounded by a deformation limiter having a plurality of troughs and crests. All of the troughs and crests are substantially aligned with one another.
Claims31
A gasket, comprising:
- at least one metallic layer having at least one combustion gas through-opening and at least one fastener through-opening, wherein said fastener through-opening is at least partially circumferentially bounded by a deformation limiter entirely comprised of a plurality of linearly aligned troughs and crests, wherein all of said troughs and crests are substantially parallel with one another around said fastener through-opening along a longitudinal axis of said layer.
A gasket, comprising:
- at least one metallic layer having at least one combustion gas through-opening and at least one fastener through-opening;
- a deformation limiter comprised of a first cohort of a plurality of troughs and crests extending from an innermost peripheral edge of said fastener through-opening to an outer terminal periphery and being only one trough or one crest deep from said fastener through-opening to said outer terminal periphery, said first cohort comprised of a first portion having at least one trough or crest that extends radially from said peripheral edge to said outer terminal periphery, said first cohort also comprised of a second portion having a plurality of troughs and crests extending non-radially between said peripheral edge to said outer terminal periphery.
A gasket, comprising:
- at least one metallic layer having at least one combustion gas through-opening, a first fastener through-opening and at least a second fastener through-opening, wherein said first fastener through-opening is at least partially circumferentially bounded by a first deformation limiter and said second through-opening is at least partially circumferentially bounded by a second deformation limiter, wherein both of said deformation limiters are comprised of a plurality of troughs and crests, wherein the troughs and crests of said first deformation limiter are substantially aligned with one another around said first fastener through-opening along a first direction and said troughs and crests of said second deformation limiter are all aligned with one another in a second direction different than said first direction.
A gasket, comprising:
- at least one metallic layer having an outermost peripheral edge that entirely bounds at least one combustion gas through-opening and at least two fastener through-openings;
- a half bead unitary with said layer and at least partially located immediately inwardly adjacent said outer peripheral edge;
- a first deformation limiter unitary with said layer, or an adjacent layer, and extending substantially continuously from one of said fastener through-openings to another of said fastener through-openings;
- a second deformation limiter unitary with said layer, or an adjacent layer, separated from said first deformation limiter, and located between one of said fastener through-openings and said edge;
- wherein said first and second deformation limiters are both comprised of a plurality of linearly aligned troughs and crests, wherein all of said troughs and crests are substantially parallel with one another.

A gasket, comprising:
- at least one metallic layer having an outermost peripheral edge defining a substantially rectangular gasket with at least one short side and two long sides, said edge entirely bounding at least one combustion gas through-opening, a first corner fastener through-opening, at least a second corner fastener through-opening and at least two side fastener through-openings all in said layer;
- a first deformation limiter, unitary with said layer, continuously extending at least partially about said first corner fastener through-opening, entirely along said short side and at least partially about said second corner fastener through-opening;
- a half bead, unitary with said layer, or an adjacent layer, extending between the outermost peripheral edge and the at least one combustion gas through-opening;
- wherein said deformation limiter comprises a plurality of linearly aligned troughs and crests, wherein all of said troughs and crests are substantially parallel with one another.

- a first bank of combustion gas through-openings in said layer and at least a second, separate bank of combustion gas through-openings in said layer;
- a first set of fastener through-openings in said layer outboard of said first bank of combustion gas through-openings;
- a second set of fastener through-openings in said layer outboard of said second bank of combustion gas through-openings;
- a third set of fastener through-openings in said layer located between said first bank of combustion gas through-openings and said second bank of combustion gas through-openings;
- a first deformation limiter unitary with said layer and continuously extending along one edge of said layer and at least partially bounding at least one fastener through-opening of said first set, at least one fastener through-opening of said second set and at least one fastener through-opening of said third set
- wherein said first deformation limiter is comprised of a plurality of linearly aligned troughs and crests that are substantially parallel with one another.
