ABSTRACT:
A steel laminate gasket of the invention is designed to be installed in an internal combustion engine having at least one hole to be sealed. The gasket comprises first and third plates having beads around the hole, and a second plate situated between the first and third plates. The second plate does not extend adjacent to the hole. When the gasket is assembled, edge portions of the first and third plates directly face against each other, but the second plate terminates at a portion between or outside the beads. The gasket may provide moderate surface pressure at a portion slightly away from the hole to be sealed to prevent deformation of the engine parts. High surface pressure may be formed near the hole to be sealed.
