MULTILAYER STATIC GASKET DISTANCE LAYER WITH IMPROVED STOPPER REGION THEREFOR AND METHOD OF CONSTRUCTION THEREOF

摘要

A multilayer static gasket stopper region containing distance layer therefor and methods of construction thereof are provided. The gasket includes at least one metal functional layer and at distance layer including a stopper region. The functional layer has a seal bead surrounding at least one passage to be sealed. The distance layer has a thickness extending between generally planar opposite sides with each of the opposite sides of the distance layer having a plurality of protrusions extending outwardly therefrom and a plurality of depressions extending inwardly therein wherein the protrusions and depressions form the stopper region. Each of the depressions extends into a separate protrusion thereby forming an underside of the associated protrusion. The depressions extend into the opposite sides of the distance layer a distance that is equal to or greater than 1/2 of the thickness of the distance layer.
