摘要： A head gasket is provided for use in an engine having a cylinder head and a cylinder liner with a side wall defining a combustion chamber, the cylinder liner including a liner flange projecting from the side wall in an outward direction away from the combustion chamber. The head gasket includes a main body layer and a flange layer coupled to the main body layer by a flange wrap portion. The flange wrap portion is sized for axial alignment with the side wall of the cylinder liner, and the flange layer is spaced from the main body layer to define a gap between the main body layer and the flange layer adjacent the flange wrap portion. A core layer is coupled to the main body layer and includes a sealing bead spaced outwardly from the flange wrap portion and sized for axial alignment with the liner flange.

摘要： A metallic gasket including a base plate having a convex metal bead formed, by bending the base plate, between a combustion chamber opening and on the outer periphery portion of the base plate, and a first thickness-increased portion formed thicker than the remaining portions of the base plate to provide a difference in thickness, by which a surface pressure is made to concentrate on the first thickness-increased portion to seal a joint between a cylinder head and a cylinder block when the metallic gasket is disposed between the joint surfaces of the cylinder head and the cylinder block and fastened by clamping bolts. An elastic sealing material is fixed to the convex portion of the metal bead and filled in a concave portion on the reverse side of the base plate to form a rubber bead, and the sealing material is deformed under compression in the through-thickness direction in cooperation with the deformation of the metal bead when the gasket is fastened with clamping bolts. This gasket reduces production cost and preserves a stable sealing performance for extended periods of time.

摘要： Cylinder head gasket with a ring-shaped combustion chamber sealing element comprising a metallic sealing strand and enclosing a combustion chamber through-opening, the combustion chamber sealing element being shaped and held in the cylinder head gasket so that when the gasket is clamped between engine component sealing surfaces, and the engine component sealing surfaces become displaced parallel to the gasket plane and relative to one another during operation of the engine, sealing element sections are tiltable about the longitudinal center axis of the sealing strand; to minimize frictional wear on the engine component sealing surfaces during operation of the engine, the gasket is shaped so that for pressing the combustion chamber sealing element against the engine component sealing surfaces, the combustion chamber sealing element is uncovered at the two main surfaces of the cylinder head gasket and, in cross section perpendicular to the longitudinal center axis of the sealing strand, is of such spherical shape there as to result, at the main surfaces of the cylinder head gasket, in surfaces of the combustion chamber sealing element, which are of convex cross section, and the radius of curvature of which is greater than half the thickness of the combustion chamber sealing element measured perpendicularly to the gasket plane so as to also minimize the danger of indentations occurring in the engine component sealing surfaces.

摘要： A multi-layered cylinder head gasket for positioning between a cylinder head and a cylinder block of an engine includes upper and lower compression layers and a stopper layer. The compression layers and stopper layer all include apertures that mate together to define a peripheral edge. The stopper layer further includes a folded portion and a main body portion. The folded portion has a plurality of waves that contact the main body portion of the stopper layer to form a stopper when folded over. The stopper is positioned at the peripheral edge of the mated aperture. The waves deform under high compression loads generated by the joining of the cylinder head and the cylinder block. The deformation balances the stresses generated by the compression loads around the mated aperture.
