Abstract
A metal static gasket and method of construction thereof is provided. The gasket includes at least one metal layer. At least one of the metal layers has opposite sides with at least one through opening extending through the opposite sides, with the through opening being configured to register with an opening to be sealed. At least one metal layer of the gasket has least one raised annular seal bead extending adjacent the through opening. A plurality of protrusions extend outwardly from at least one of the opposite sides, wherein the plurality of protrusions are formed from separate pieces of metal from the at least one metal layer and are individually fixed to the at least one metal layer via separate bond joints.
Claims20
A static gasket, comprising:
- at least one metal layer having opposite sides and at least one through opening extending through said opposite sides, at least one of said at least one metal layer having a raised annular seal bead extending about said at least one through opening;
- and
- a plurality of protrusions extending outwardly from at least one of said opposite sides between said at least one through opening and said raised annular seal bead to prevent the complete flattening of said raised annular seal bead, said plurality of protrusions being constructed from separate pieces of metal from one another and from said at least one metal layer and being individually fixed to said at least one metal layer via separate bond joints.
A method of constructing a static gasket, comprising:
- providing at least one metal layer having opposite sides and at least one through opening with at least one of said at least one metal layer having at least one raised annular seal bead adjacent said at least one through opening;
- and
- bonding a plurality of separate pieces of metal to at least one of said opposite sides of said at least one metal layer between said through opening and said at least one raised annular seal bead to prevent the complete flattening of said at least one raised annular seal bead.
