Patent ID: 8596645

Claim:
A first housing portion having a first wall member that defines a first internal cavity, a first inner surface, a first outer surface and a first end face that extends between the first inner surface and the first outer surface, the internal cavity adapted to be filled with a pressurized fluid; a second housing portion having a second wall member that defines a second internal cavity, a second inner surface, a second outer surface and a second end face that extends between the second inner surface and the second outer surface; a gasket disposed axially between the first and second housing portions and sealingly engaging the first and second end faces, the gasket including a plurality of gasket bosses and at least one projecting portion that is located between two adjacent ones of the plurality of gasket bosses, each of the gasket bosses being adapted for receiving a threaded fastener there through; at least one recess formed in the first end face and not intersecting either of the first inner surface and the second inner surface; and a plurality of threaded fasteners that generate a clamping force that is transmitted through the first housing portion, the gasket and the second housing portion; wherein the at least one projecting portion extends into the at least one recess to limit laterally outward movement of the gasket between the first and second end faces relative to the first and second housing portions, and wherein the at least one projecting portion is preformed prior to any compression of any portion of the gasket between the first and second housing portions; and wherein the gasket defines first and second sealing surfaces that abut the first and second end faces, respectively, and wherein the at least one projecting portion extends axially from the first sealing surface by a predetermined distance that is greater than zero when the gasket is in an initially formed, uncompressed state.
