Abstract
In order to provide a flat gasket comprising at least one gasket sheet, which comprises at least one through-opening and at least one sealing bead, which extends around the through-opening and is delimited at the side facing the through-opening by an inner bead foot, and at the side remote from the through-opening by an outer bead foot, and at least one deformation-limiting device, which comprises at least one stopper element disposed on a stopper-supporting surface of the gasket sheet, in which flat gasket the effective stopper height of the stopper element may easily be set to a value that differs from the thickness of the stopper element, the stopper-supporting surface is shifted in a direction extending at right angles to the stopper-supporting surface by an offset.

A flat gasket, comprising at least one gasket sheet, which comprises at least one through-opening and at least one sealing bead, which extends around the through-opening and is delimited at the side facing the through-opening by an inner bead foot and at the side remote from the through-opening by an outer bead foot and has a bead crest extending between the inner bead foot and the outer bead foot, and
- at least one deformation-limiting device, which limits the deformation of the sealing bead and comprises at least one stopper element disposed on a stopper-supporting surface of the gasket sheet,
- wherein the stopper-supporting surface is shifted in a direction extending at right angles to the stopper-supporting surface by an offset relative to a part of the surface of the gasket sheet that adjoins the outer bead foot and is situated outside of the sealing bead and disposed at the same side of the gasket sheet as the stopper-supporting surface,
- wherein the sealing bead is designed asymmetrically in relation to a plane extending through its bead crest and at right angles to the stopper-supporting surface, wherein the inner bead foot extends at a different height level to the outer bead foot,
- wherein the flat gasket, besides the gasket sheet that is provided with the sealing bead and the stopper element, additionally comprises at least one carrier sheet with an offset region, wherein the flat gasket comprises at least one further gasket sheet, which is provided with at least one elastically vertically deformable sealing bead extending around the through-opening and is disposed at the side of the carrier sheet that is facing away from the gasket sheet provided with the sealing bead and the stopper element,
- wherein the offset region of the carrier sheet serves as a deformation-limiting device for the elastically vertically deformable sealing bead of said further gasket sheet,
- wherein a first side of the offset region of the carrier sheet facing towards the gasket sheet provided with the sealing bead and the stopper element is offset towards said further gasket sheet by a first offset having a first maximum height (Δ) and a second side of the offset region of the carrier sheet facing towards said further gasket sheet is offset towards said further gasket sheet by a second offset having a second maximum height (Δ′),
- wherein the second maximum height (Δ′) is smaller than the first maximum height (Δ), and
- wherein the radial position of the first offset and the radial position of the second offset are both disposed between the through-opening and the radial position of the crest of the sealing bead.
A flat gasket, comprising at least one gasket sheet, which comprises at least one through-opening and at least one sealing bead, which extends around the through-opening and is delimited at the side facing the through-opening by an inner bead foot and at the side remote from the through-opening by an outer bead foot and has a bead crest extending between the inner bead foot and the outer bead foot, and
- at least one deformation-limiting device, which limits the deformation of the sealing bead and comprises at least one stopper element disposed on a stopper-supporting surface of the gasket sheet,
- wherein the stopper-supporting surface is shifted in a direction extending at right angles to the stopper-supporting surface by an offset relative to a part of the surface of the gasket sheet that adjoins the outer bead foot and is situated outside of the sealing bead and disposed at the same side of the gasket sheet as the stopper-supporting surface,
- wherein the sealing bead is designed asymmetrically in relation to a plane extending through its bead crest and at right angles to the stopper-supporting surface, wherein the inner bead foot extends at a different height level to the outer bead foot,
- wherein the flat gasket, besides the gasket sheet that is provided with the sealing bead and the stopper element, additionally comprises at least one carrier sheet with an offset region,
- wherein the flat gasket comprises at least one further gasket sheet,
- which is provided with at least one sealing bead extending around the through-opening and is disposed at the side of the carrier sheet that is facing away from the gasket sheet provided with the sealing bead and the stopper element,
- wherein the offset region of the carrier sheet serves as a deformation-limiting device for the sealing bead of said further gasket sheet,
- wherein the flat gasket, besides the gasket sheet that is provided with the sealing bead and the stopper element and said further gasket sheet, additionally comprises at least one further gasket sheet, which is provided with at least one sealing bead extending around the through-opening,
- wherein a first side of the offset region of the carrier sheet facing towards the gasket sheet provided with the sealing bead and the stopper element is offset towards said further gasket sheet by a first offset having a first maximum height (Δ) and a second side of the offset region of the carrier sheet facing towards said further gasket sheet is offset towards said further gasket sheet by a second offset having a second maximum height (Δ′),
- wherein the second maximum height (Δ′) is smaller than the first maximum height (Δ), and
- wherein the radial position of the first offset and the radial position of the second offset are both disposed between the through-opening and the radial position of the crest of the sealing bead.
A flat gasket, comprising at least one gasket sheet, which comprises at least one through-opening and at least one sealing bead, which extends around the through-opening and is delimited at the side facing the through-opening by an inner bead foot and at the side remote from the through-opening by an outer bead foot and has a bead crest extending between the inner bead foot and the outer bead foot, and
- at least one deformation-limiting device, which limits the deformation of the sealing bead and comprises at least one stopper element disposed on a stopper-supporting surface of the gasket sheet,
- wherein the stopper-supporting surface is shifted in a direction extending at right angles to the stopper-supporting surface by an offset relative to a part of the surface of the gasket sheet that adjoins the outer bead foot and is situated outside of the sealing bead and disposed at the same side of the gasket sheet as the stopper-supporting surface,
- wherein the sealing bead is designed asymmetrically in relation to a plane extending through its bead crest and at right angles to the stopper-supporting surface, wherein the inner bead foot extends at a different height level to the outer bead foot,
- wherein the flat gasket, besides the gasket sheet that is provided with the sealing bead and the stopper element, additionally comprises at least one carrier sheet with an offset region,
- wherein the flat gasket comprises at least one further gasket sheet,
- which is provided with at least one sealing bead extending around the through-opening and is disposed at the side of the carrier sheet that is facing away from the gasket sheet provided with the sealing bead and the stopper element,
