Abstract
A cylinder head sealing arrangement for reciprocating piston engines, especially internal combustion engines. An end of each cylinder liner that faces a cylinder head is provided with a raised collar that includes a centering portion. A preferably metallic combustion chamber seal in the form of a ring having a constant thickness in a starting position is guided with clearance fit. When cylinder head screws are tightened, the ring undergoes a plastic deformation of at least one end face. The ring has an inner surface that is guided relative to the centering portion only via a cylindrical guide region of the ring or the raised collar. The free space between the ring and the centering portion increases continuously proceeding from the guide region so that after plastic deformation the ring rests flat upon the cylinder liner beyond the region of a radius that defines a transition between the liner and the collar.
