Appl. No.:

11/158664

Inventors:

Gregory Sandford - Chicago IL, US
Paul Fatora - Woodridge IL, US

International Classification:

F02F 11/00

US Classification:

277595000

Abstract:

An exhaust manifold gasket having a gasket body including at least two metal plates defining a first surface and a second surface is described herein. The body has a plurality of service openings defining at least one exhaust hole and a plurality of bolt holes. The second surface includes a foldover around a perimeter of the body. A thermally resistant layer may be located between the first surface and the second surface and extends beyond a sealing region of the gasket. A load limiting layer that works to prevent excess compression at the bolt holes is disposed proximate a metal plate.

Abstract:

A cylinder head gasket seals combustion chamber openings with two exterior active sealing layers and a central spacer layer. In web areas between adjacent combustion openings, each opening beginning of the active layers has a land, where a circumferential main stopper is formed with the central spacer layer between the lands. Each active layer further has longitudinal waves formed with the active layer which, when compressed, form a longitudinal support wave stopper(s) in the web areas. Each web area active layer further has a full bead(s) in contact with the central spacer layer. For each exterior layer, in one case, two beads come together to form a single central web area bead that separates two wave stoppers. In another case, the two outer bead portions come together upon entering the central web area while a single wave stopper is formed between the two inner bead portions.
