CYLINDER HEAD GASKET FOR HIGH LOAD AND MOTION APPLICATIONS

摘要

A cylinder head gasket including at least three functional layers and at least two stoppers is provided. The first functional layer includes a first full bead extending around a combustion chamber opening and axially aligned with a second full bead of the second functional layer. The first stopper extends along the first functional layer between the combustion chamber opening and the first full bead for preventing over-compression of the first full bead. The second stopper is located beneath the second full bead of the second functional layer for increasing load on the second full bead, reducing head lift, and promoting an even distribution of the load. The second stopper is not attached to the second functional layer along and adjacent the second full bead, and thus an air gap is present between the second stopper and the second full bead when the gasket is not compressed.

主权项

1. A gasket, comprising:
a first functional layer including a first outer surface and an oppositely facing first inner surface and extending between a first edge surrounding a combustion chamber opening and a second edge; a portion of said first outer surface and said first inner surface extending in a first direction to present a first full bead around said combustion chamber opening; a second functional layer including a second inner surface facing said first inner surface and an oppositely facing second outer surface and extending between a third edge surrounding said combustion chamber opening and a fourth edge; a portion of said second inner surface and said second outer surface 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 first stopper extending along said first inner surface of said first functional layer between said first edge and said first full bead; a second stopper extending along said second outer surface of said second functional layer; and said second stopper being attached to said second outer surface around said second full bead and spaced from said second outer surface at said second full bead.
