Abstract
A multilayer metal gasket () for establishing a seal between two mating members, such as between a cylinder head () and an engine block (). The gasket assembly () includes a primary functional layer () having an embossed primary sealing bead (). A primary stopper layer () bridges the convex embossed portion of the primary sealing bead and is fixed relative to the primary functional layer () by welding () or clinching. A secondary functional layer () is paired with the primary functional layer () and inverted relative thereto so that its secondary sealing bead () aligns with the primary sealing bead () and their respective concave depressions open toward one another, with the primary stopper layer () sandwiched therebetween. A compression limiter () may be carried on the functional layer () or alternatively a distance layer (). The assembly () may include a tertiary functional layer () having a tertiary sealing bead () inverted relative to, and aligned directly with, the primary sealing bead ().
