Abstract

Device for sealing a combustion chamber of a combustion engine, which combustion chamber is bounded by a cylinder liner, preferably replaceable and is surrounded by a cylinder block, a piston and a cylinder head. A disc-shaped sealing element is pressed in between the cylinder liner and the cylinder head, where either the liner or the cylinder head is provided with an annular protruding portion and the other one of them with a corresponding recess into which the sealing element is pressed. The protruding portion has a greater radial width than the recess.
