A gasket has a first active layer with a bead. A first spacer layer is located below the first active layer. An intermediate layer is provided with a wave portion. The intermediate layer is located below the first spacer layer. A bottom spacer layer is located beneath the intermediate layer. The bottom spacer may have a bead.

Gasket with engine liner accomodation

An embodiment provides a MLS gasket that includes a metal layer having an external periphery, an upper surface generally defining a first plane, and a lower surface generally defining a second plane. The first and second planes define a layer thickness therebetween. At least one cylinder aperture is formed in the metal layer. The metal layer includes a stopper portion formed adjacent at least a portion of the external periphery. The stopper portion is formed such that at least a portion of the stopper portion extends above the first plane. At least a portion of the stopper portion extends below the second plane. An average thickness of the stopper portion is less than the layer thickness. The gasket also includes a first sealing layer adjacent the metal layer. The first sealing layer includes a first bead portion. Compression of the first bead portion is selectively limited by the stopper portion.

MLS gasket compression limiter

A gasket having a layer including at least one combustion opening and a wave area located on the layer is disclosed. The wave area includes a first wave and a second wave. The first wave is proximate the combustion opening. A flat portion near the second wave includes a first end and a second end. A full bead is located next to the second end of the flat portion whereby a lower surface of the flat portion is above the lower projecting surfaces of the wave area.

Optimized wave bead with full bead design

A seal of an annular shape comprising a top bead and a side bead that are tilted inwardly at predetermined angles. The top bead and side bead are integrally formed such that a force exerted on the side bead allows the side bead to cooperate with the top bead to properly seal an intake pipe within a cylinder head.
