Abstract
A cylinder-head gasket has an elongated compressible heat-resistant sheet having a longitudinally extending succession of circular cylinder holes. Respective U-section sheet-metal rings are gripped over the edges of these holes on the sheet. Respective sections of reinforcement material are engaged between these rings and the sheet in a longitudinally extending central region of the sheet that has a width smaller than the diameter of the cylinder holes. The reinforcement material is different from the sheet metal of the rings and is heat resistant.
