Gasket assembly
The gasket assembly includes a gasket layer and a separately formed shim layer. The shim layer and gasket layer are formed with at least one media-conveying opening that correspond to media-conveying passages communicating between first and second members to be clamped together and sealed by the gasket at the joint between members. The shim layer has an adhesive layer applied to its back surface 36 to enable the shim layer 14 to be adhered to original clamping face of the one of the first or second members in order to build up the surface or to cover up damage on the clamping face that could impair proper sealing with the gasket.
1 . A gasket shim for use with a static gasket comprising:
a metal layer having opposite upper and lower clamping surface and at least one opening through said layer;
said layer having a thickness no greater than about 0.005 inches; and
an adhesive applied to one of said upper and lower surfaces.
2 . The shim of claim 1 wherein said layer includes a plurality of openings at least one of which is a media-conveying opening.
3 . The shim of claim 1 said adhesive is thinner than said metal layer.
4 . The shim of claim 1 wherein said metal layer has a general gasket, shape corresponding to that of the static gasket for which it is to be used.
5 . A gasket assembly, comprising a static gasket having at least one media-conveying opening;
at least one shim layer formed separately from said static gasket having a first clamping surface engaging said static gasket and a second opposite surface and at least one media-conveying opening aligned with said at least one media conveying opening of said static gasket; and
an adhesive layer applied to said opposite surface.
6 . The assembly of claim 6 wherein said shim layer includes a plurality of openings.
7 . The assembly of claim 5 wherein said adhesive is spaced from said static gasket.
8 . A method of sealing a gap between opposing clamping surfaces of two members to be sealed, comprising;
adhering a shim layer to at least one of the clamping surfaces;
positioning a gasket over at least one shim layer and clamping the members together.
10 . The method of claim 8 including limiting the thickness of the shim layer to 0.005 inches or less.
11 . The method of 8 including aligning media-conveying openings of the shim layer and gasket with associated openings of the members to be sealed.
12 . The method of claim 8 including adhering a shim layer to the other clamping surface such that the gasket layer is positioned and clamped between the two shim layers adhered to the clamping surfaces of the two members to be sealed.
