ABSTRACT:
A gasket assembly including a metal core member having spaced parallel first and second faces with an annular cylinder bore opening therein. The core member includes an offset portion extending about the periphery of the opening. The offset portion has a first surface raised above one face of the core member and a second surface recessed below the other face of the core member. The offset portion is integrally formed with the remainder of the core member and is connected thereto through sections which have shear stresses therein. In one embodiment a U-shaped shell member is disposed about the core member and the offset portion therein and layers of compressible paper-like material are disposed on opposite sides of the core member extending from the U-shaped shell member. In another embodiment an annular skirt is integral with and extends perpendicularly from one leg of the U-shaped shell member. The shear stresses in the core member at the extremities of the offset portion provide compressive strengths heretofore unobtainable.
