초록 ▼

A gasket for sealing the connection between a cylinder head and a valve cover. The gasket has a sheet metal backbone having a main body with spaced stations having holes therethrough for cap screws fastening a valve cover to a cylinder head. A finger-like tab extends inwardly from the stations. Each tab has a cap screw hole at the distal end thereof. The tabs are bent back over the main body so as to be in contact with the spaced stations and with the holes in the tabs and stations in alignment. The backbone has a rubber based material subsequently molded therearound. The result of the folded construction is a double thickness of metal in the areas surrounding the cap screw holes to form positive stops to limit the compression loads applied to the rubber based seal of the gasket by the cap screws when the valve cover is fastened to the cylinder head. The compression loads are thereby limited and the gasket is protected from damage by excessive loads so that effective sealing and long service life is assured.

A gasket assembly for fluid sealing the interfacing surface areas of two components to be joined together under compression loads by fasteners, said gasket assembly having a backbone of metallic material, said backbone including a main body with top and bottom sides disposed primarily in a first plane, the improvement comprising a plurality of stations in said main body spaced from one another and offset from said first plane, a fastener receiving hole formed in each of said stations, tab means integral with said main body and associated with each of said stations and extending therefrom, each of said tab means having an end portion and having a fastener receiving hole near the end portion thereof and having a reverse bend therein so that the end portion of each said tab means closely overlies at least a portion of said associated station of said main body and so that the fastener receiving hole therein is in substantial alignment with the corresponding fastener hole in said station and elastomer sealing means molded on said main body of said backbone to sealingly cover said backbone including said spaced stations and said tab means whereby said tab means and said spaced stations of said main body cooperate to provide stop means for limiting the compression loads applied to said gasket assembly by the fasteners that extend through the holes in the gasket assembly when connecting the two components together while said elastomer sealing means is operative to cover the top and bottom sides of said body and said stations and said tab means to seal the interfacing surfaces of the two components.
