Multilayer metal seal for IC engine - has two sealing layers, each consisting of connected web and ring elements

摘要

The seal has a metallic carrier layer, with passages in the area of engine combustion chambers, and with cooling and lubrication passages. It also has metallic sealing layers above and below the carrier layer, to seal combustion chambers and cooling/lubrication passages. The sealing layers consist mainly of numerous web and ring elements, which are formed by metal plate. The elements are formed along closed lines, and are arranged, so that they enclose all passages. All elements are connected to each other, and thereby form one-piece sealing layers. USE/ADVANTAGE - Multilayer metal seal for IC engine is improved so that it increases contact pressure on combustion chamber edge.
