A gasket-squeeze construction wherein a warp-limiter member is installed in a bolt hole in which a fastening bolt fits. The warp-limiter member is made less in an amount of flex than confronting surfaces, between which the gasket is disposed and squeezed by the tightening of the fastening bolt. The warp-limiter member serves to make the sealing stress uniform around a combustion gas hole. The warp-limiter member installed in the bolt hole, because of tougher to flex than the confronting surfaces when tightening the fastening bolt, makes uniform the clamping force of the fastening bolt and the compressive stress created around the associated bolt hole, moreover dispersing uniformly the sealing stress throughout around the combustion gas hole such as a cylinder bore, thereby rendering variation in distortion in the sealing joint less to improve the sealing performance.
In a squeezing construction for a gasket, in which the gasket is placed between confronting surfaces of engine components made therein with combustion gas holes and arranged in opposition to each other, and squeezed by tightening a fastening bolt to seal a joint between the confronting surfaces of engine components, the improvement wherein a warp-limiter member is installed in a bolt hole formed in the gasket in which the fastening bolt fits, the warp-limiter member being made tougher to flex than the confronting surfaces of the components, to which the warp-limiter member comes in abutment.
