Multilayer static gasket, distance layer with improved stopper area for multilayer static gasket, and method for manufacturing multilayer static gasket

摘要

A multilayer static gasket, a stopper region including a distance layer for the multilayer static gasket, and a method of manufacturing the multilayer static gasket are provided. The multilayer static gasket comprises at least one functional layer and a distance layer including a stopper region. The functional layer has a sealing bead surrounding at least one flow path to be sealed. The distance layer has a thickness extending generally between both sides of the plane, each of the both sides of the distance layer having a plurality of protrusions extending outwardly from itself and inwardly in itself. A plurality of recesses extending. The convex portion and the concave portion form a stopper region. Each of the recesses extends into another protrusion, thereby forming the back surface of the corresponding protrusion. The recess extends into both side surfaces of the distance layer at a distance of 1/2 or more of the thickness of the distance layer.
