ELASTIC SEALING MEMBER RADIALLY INWARDLY OF PRIMARY SEALING BEAD

摘要

A gasket assembly having a secondary elastic sealing bead positioned radially inwardly of the primary sealing bead. The secondary sealing bead extends circumferentially about the aperture and radially inwardly of the primary sealing bead. A stopper layer is disposed adjacent at least a portion of the gasket layer and extends radially from the outboard region to the inboard edge to radially overlap the secondary sealing bead and the primary sealing bead. The secondary sealing bead has an “S-type” structure and provides increased gasket resiliency adjacent the inboard edge.

1. A gasket assembly comprising;
at least one gasket layer having an inboard edge circumscribing at least one aperture and an outboard region radially spaced from said aperture, at least one primary sealing bead disposed along said gasket layer between said inboard edge and said outboard region wherein said primary sealing bead extends circumferentially about said aperture and radially along a first radial length, at least one secondary sealing bead disposed along said gasket layer between said primary sealing bead and said inboard edge wherein said secondary sealing bead extends along a second radial length, said secondary sealing bead having an “S-type” curved shape, wherein said secondary sealing bead provides resiliency of said gasket layer adjacent said inboard edge.
