Abstract

A multilayer static cylinder head gasket has at least one metal functional layer and a metal distance layer having registered openings. The functional layer has a full bead located radially outwardly from and extending about its opening. The opening in the distance layer is formed in a first portion having a first thickness. A second portion of the distance layer extends radially outwardly from the opening and the first portion, wherein the second portion has a second thickness that is less than the first thickness. A compression limiter is formed in at least one of the functional layer or the distance layer. The compression limiter prevents the full bead from being completely flattened, which in turn maintains the full bead in high sealing pressure against the distance layer relative to the remaining portion of the functional layer and also prevents premature fatigue cracks from forming in the full bead.
