Abstract

A gasket is provided that is suitable for use in connection with a cylinder head. The gasket includes a first outer plate including a compensating portion, a second outer plate including a compensating portion, and a compensating plate positioned between said first and second outer plates. Preferably, at least one of said first and second outer plates includes a bead positioned outside of, and in close proximity to, said compensation portion of said plate. The compensating plate includes a compensating element and an edge portion. In a preferred embodiment, the area between the compensating portions of said first and second outer plates defines a compensating area and said compensating element is positioned within said compensating area. If desired, the gasket may also include a spacer plate.
