CYLINDER HEAD GASKET WITH COMPRESSION LIMITER AND FULL BEAD LOADING

摘要

A multilayer gasket for establishing a gas and/or fluid-tight seal between a cylinder head and engine block of an internal combustion engine is provided. The gasket includes a pair of functional layers each presenting a full bead and a half bead. A single-piece stopper with a fold over adjacent the combustion chamber opening is disposed between the function layers. The stopper extends between a fifth edge and a sixth edge, wherein the sixth edge is disposed radially between the full beads and the half beads. The stopper can be cranked or coined in a location disposed between the fold over and the full beads. The stopper can also include a secondary fold over adjacent the sixth edge. A distance layer is optionally disposed between the stopper and one of the functional layers. The distance layer can also be cranked or coined between the fold over and the full beads.

主权项

1. A gasket, comprising:
a first functional layer extending from a first edge surrounding a combustion chamber opening to a second edge; a portion of said first functional layer extending in a first direction to present a first full bead around said combustion chamber opening; a portion of said first functional layer extending in said first direction to present a first half bead disposed between said first full bead and said second edge; a second functional layer extending from a third edge surrounding said combustion chamber opening to a fourth edge; a portion of said second functional layer extending in a second direction opposite said first direction to present a second full bead axially aligned with said first full bead; a portion of said second functional layer extending in said second direction to present a second half bead axially aligned with said first half bead; a stopper disposed between said functional layers and extending between a fifth edge and a sixth edge, wherein said sixth edge is disposed radially between said full beads and said half beads; and said stopper including a fold over presenting an increased thickness between said fifth edge and said full beads.
