Abstract

La présente invention concerne un joint de type à empilement comprenant une pluralité de plaques qui sont couplées au moyen de calfatages et des saillies empêchant un blocage sont formées sur les calfatages d'au moins une des plaques. Par conséquent, étant donné que les saillies destinées à empêcher un blocage sont formées sur au moins une plaque de la pluralité des plaques, il est possible d'empêcher des joints du type à empilement de se bloquer ou de se caler les uns sur les autres. En conséquence, un travail de montage peut être effectué facilement et il est possible d'empêcher deux joints de type à empilement ou plus de s'interposer entre les surfaces de jonction d'une tête de cylindre et d'un bloc cylindre.
