Abstract

A static gasket configured for establishing a seal between a cylinder head and an engine block including at least one layer having an opening and at least one compression bead. The compression bead extends circumferentially about the opening and projects out of a plane for deforming elastically when the gasket is compressed between the cylinder head and the engine block. A compression limiter which is formed from a metal wire is disposed radially between the opening and the compression bead for preventing the compression bead from being fully flattened, even if the cylinder head is overloaded onto the engine block. The compression bead is preferably induction and/or resistance welded to at least one of the layer(s).

Claims (30)

1. A method of forming a static gasket for establishing a gastight seal between two members to be clamped together, comprising the steps of:

bending a vertical wall into a gasket layer which extends at least partially along a horizontal plane which has an opening;

inserting a wire around the vertical wall;

compressing the wire against the layer after the wire is inserted around the vertical wall to at least partially flatten the wire;

resistance or induction welding the wire to the gasket layer; and

forming a compression bead into said gasket layer or engaging said gasket layer with another layer than has a compression bead.

2. The method as set forth in claim 1 wherein the gasket layer is a functional layer, and further including the step of embossing the functional layer to present a compression bead.

3. The method as set forth III claim 1 further including the step of removing the vertical wall from the gasket layer.

4. A method of forming a static gasket for establishing a gas-tight seal between two members to be clamped together, comprising the steps of:

drawing a vertical wall into a layer which extends at least partially along a horizontal plane;

inserting a wire around the vertical wall;

compressing the wire against the layer to at least partially flatten the wire; and

resistance or induction welding the wire to the layer; and

wherein the step of compressing the wire against the functional layer is further defined as coining the wire against the layer to at least partially flatten the wire.

5. A method of forming a static gasket for establishing a gas-tight seal between two members to be clamped together, comprising the steps of:

providing a wire of metal;

bending the wire into an enclosed shape;

providing at least one functional layer having an opening and a compression bead;

engaging the wire with the at least one functional layer around the opening;

compressing the wire against the at least one functional layer after the wire is engaged with the at least one functional layer to at least partially flatten the wire; and

welding the wire to the functional layer between the opening and the compression bead to prevent the compression bead from being flattened between the two members.

6. The method as set forth in claim 5 further including the step of forming the wire into a compression limiter and wherein the step of welding the compression limiter to the functional layer is further defined as induction welding or resistance welding the compression limiter to the functional layer.

7. The method as set forth in claim 6 further including the step of shaping the wire to have a generally flat top and a generally flat bottom before the step of induction welding the compression limiter to the functional layer.

8. The method as set forth in claim 7 wherein the step of shaping the wire is further defined as shaping the wire on a forming die.

9. The method as set forth in claim 7 wherein the step of shaping the wire is further defined as shaping the wire to have a variable topography.

10. The method as set forth in claim 7 further including the step of coining an edge of the functional layer to present a lip extending radially into the opening and wherein the compression limiter is at least partially welded to the lip.

11. The method as set forth in claim 6 further including the step of providing a second functional layer and further including the step of sandwiching the compression limiter between the functional layers.

12. The method as set forth in claim 5 wherein the step of bending the wire into an enclosed shape is further defined as bending the wire into a generally circular shape.

13. The method as set forth in claim 12 further including the step of welding the ends of the wire together.

14. The method as set forth in claim 5 wherein each of the openings in the functional layers is generally circular.
