ABSTRACT:
A gasket for sealing the joint between the cylinder block and the cylinder head of a wet liner internal combustion engine comprising a pair of outer metal plates (1), a metal spacer plate (2) between the two outer plates and comprised of an essential soft metal layer and hard metal surface layers there being fitted around each cylinder bore opening a metal washer (7) formed on each axial face with circumferential serrations (7a) of V-shaped profile. The thickness of the washer (7) measured over the peaks of the corrugations (7a) is somewhat greater than that of the spacer plate (2) whereas the thickness measured between the troughs of the serrations (7a) is significantly less than that of the spacer plate (2). According to the invention the outer metal plates (1) and central metal plates (2) have their edges spaced away from the individual cylinder bore openings whereas the washer (7) has its radially inner portion formed with the serrations (7a) which extend to the edge of the bore openings, whereas only its radially outer part is accommodated between the two outer metal plates (1).
