Abstract

La présente invention concerne un joint de culasse (1) comprenant : une paire de feuilles de base de joint (4, 5) comprenant des trous de chambre de combustion (8) et des nervures de renforcement pleines (4a, 5a) entourant les trous de chambre de combustion (8) ; une feuille intermédiaire (6) disposée entre la paire de feuilles de base de joint ; et une feuille de calage (7) disposée entre la feuille intermédiaire et l'une des feuilles de base de joint. La feuille de calage (7) est positionnée sur les nervures de renforcement pleines, et des premières moitiés de nervure de renforcement (4b, 5b) sont formées sur les feuilles de base de joint en des emplacements de sorte que les premières moitiés de nervure de renforcement (4b, 5b) entourent les nervures de renforcement pleines et ne soient pas positionnées sur la feuille de calage. Un trou d'eau (10) est formé à l'extérieur d'une région entourée des premières moitiés de nervure de renforcement, et en outre les premières moitiés de nervure de renforcement sont disposées à distance les unes des autres en des emplacements proches des trous de chambre de combustion dans un état dans lequel un axe reliant les centres des trous de combustion est disposé entre les premières moitiés de nervure de renforcement. Un liquide de refroidissement ne peut pas s'écouler dans les espaces entre des nervures de renforcement voisines de façon à empêcher la séparation d'un revêtement.
