Abstract
Official abstract text for this publication.
A metal static gasket and method of construction thereof is provided. The gasket includes at least one metal layer. The at least one metal layer has opposite sides with at least one through opening extending through the opposite sides configured to register with an opening to be sealed and at least one raised annular seal bead extending at least in part about the at least one through opening. At least one protrusion extends outwardly from at least one of the sides, wherein the at least one protrusion prevents complete flattening of the at least one seal bead. The at least one protrusion has a plurality of discrete layers of metal deposited on one another via an additive manufacture process, wherein the protrusion is formed having a hollow region extending therein.
First claim
Opening claim text (preview).
What is claimed is: 1. A gasket, comprising: at least one metal layer having opposite sides and at least one through opening extending through said opposite sides and at least one raised annular seal bead and having at least one protrusion extending outwardly from at least one of said sides; said at least one protrusion having discrete layers of metal deposited on one another via an additive manufacture process; and wherein said at least one protrusion has a hollow, internal void surrounded by the metal of said discrete layers. 2. The gasket of claim 1 wherein the at least one protrusion is provided as a plurality of protrusions, with at least some of the protrusions differing in height from one another. 3. The gasket of claim 1 wherein the at least one protrusion is provided as a plurality of protrusions, with at least some of the protrusions differing in peripheral shape from one another. 4. The gasket of claim 1 wherein the at least one protrusion is provided as a plurality of protrusions, with at least some of the protrusions differing in density from one another. 5. The gasket of claim 1 wherein the at least one protrusion is provided as a plurality of protrusions, with at least some of the protrusions differing in material from one another. 6. The gasket of claim 1 wherein at least some of the discrete layers have a different density from one another. 7. The gasket of claim 1 wherein at least some of the discrete layers are formed of different materials from one another. 8. The gasket of claim 1 wherein the at least one protrusion has an external recess. 9. The gasket of claim 1 wherein the hollow, internal void is fully encapsulated by the metal of said discrete layers. 10. The gasket of claim 1 wherein the hollow, internal void extends through the metal of said discrete layers to form a through channel.
