Abstract

A seal of an annular shape comprising a top bead and a side bead that are tilted inwardly at predetermined angles. The top bead and side bead are integrally formed such that a force exerted on the side bead allows the side bead to cooperate with the top bead to properly seal an intake pipe within a cylinder head. This abstract submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Claims (33)

1. A sealing ring having an upper surface and a lower surface comprising:

a top bead disposed proximate the upper surface, wherein said top bead is tilted inwardly at a predetermined angle;

a side bead disposed between said top bead and the lower surface, wherein a top portion of said side bead is tilted inwardly relative to an intake pipe, at a predetermined angle relative to an axial axis defined by the sealing ring, such that said side bead extends outwardly away from an outside edge of said top bead wherein only said side bead contacts an inside surface of the intake pipe;

wherein said seal has a generally annular shape;

wherein said top bead and said side bead are integrally joined, such that said side bead cooperates with said top bead to properly seal the intake pipe within a cylinder head; and

wherein said side bead cooperates with said top bead to ensure said top bead remains flush against a surface of a wall when a force is exerted on said side bead, whereby said top bead and said side bead never overlap.

2. A seal according to claim 1 , wherein said side bead is positioned flush against a surface of the intake pipe.

3. A seal according to claim 1 , wherein said side bead is positioned below an edge of the intake pipe.

4. A seal according to claim 1 , wherein said top bead and said side bead are generally parallel with respect to each other.

5. A seal according to claim 4 , wherein said top bead is generally parallel to a surface of the cylinder head and said side bead is generally parallel to said surface of the intake pipe.

6. A seal according to claim 1 , wherein said predetermined angle of said top bead is between ten to fourteen degrees.

7. A seal according to claim 1 , wherein said predetermined angle of said top bead is twelve degree.

8. A seal according to claim 1 , wherein said predetermined angle of said side bead is between thirteen to seventeen degrees.

9. A seal according to claim 1 , wherein said predetermined angle of said side bead is fifteen degrees.

10. A seal according to claim 1 , wherein said seal is only made of an elastomeric material.

11. A sealing ring comprising:

an annular body defining an aperture and an axial axis between an upper surface and a lower surface, said annular body having an outer surface;

a top bead disposed proximate said upper surface, wherein said top bead is tilted inwardly relative to said axial axis at a predetermined angle;

a side bead disposed between said top bead and said lower surface, wherein a top portion of said side bead is tilted inwardly relative to said axial axis at a predetermined angle such that said side bead extends away from an outside edge of said top bead; and

a flange portion extending downwardly from said lower surface;

wherein said top bead and said side bead are integrally joined, such that said side bead cooperates with said top bead so that a force acted upon said side bead is transmitted to said top bead to deform said top bead.

12. A seal according to claim 11 , wherein said top bead and said side bead not in an overlapping relationship.

13. A seal according to claim 11 , wherein said outer surface is generally parallel to said axial axis.

14. A seal according to claim 11 , wherein said flange portion is generally parallel to said outer surface.

15. A seal according to claim 11 , wherein said predetermined angle of said top bead is twelve degrees.

16. A seal according to claim 11 , wherein said predetermined angle of said side bead is between thirteen to seventeen degrees.

17. A seal according to claim 11 , wherein said predetermined angle of said side bead is fifteen degrees.

18. A sealing ring comprising:

an annular body defining an aperture and an axial axis between an upper surface and a lower surface, said annular body having an outer surface generally parallel to said axial axis;

a top bead disposed proximate said upper surface, wherein said top bead is tilted inwardly relative to said axial axis at a predetermined angle;

a side bead disposed between said top bead and said lower surface, wherein a top portion of said side bead is tilted inwardly relative to said axial axis at a predetermined angle such that said side bead extends away from an outside edge of said top bead; and

a flange portion extending downwardly from said lower surface;

wherein said top bead and said side bead are integrally joined, such that said side bead cooperates with said top bead so that a force acted upon said side bead is transmitted to said top bead to deform said top bead, wherein said top bead and said side bead are never in an overlapping relationship.
