Patent number: 6688606Abstract: The invention refers to gaskets suitable for usage in internal combustion engines. The gaskets according to the invention comprise at least one metal layer, the metal layer having one or several openings in accordance with the number and location of the combustion chambers, and, if present, coolant and lubricant passageways of the internal combustion engine, and a metal ring located around the combustion chamber opening(s), the metal ring being laminated on the metal layer and joined to the latter over a plastic layer. The plastic layer provides the gasket in the region of the metal ring with plastic, plastic/elastic or elastic characteristics. Furthermore the invention refers to a method for manufacturing the gasket according to the invention.Type: GrantFiled: May 4, 2001Date of Patent: February 10, 2004Assignee: Reinz-Dichtungs-GmbH CO.
