The present invention relates to a multi-layered steel gasket, for example a cylinder head gasket, having at least one through-opening, for example for a combustion chamber of an internal combustion engine, in which at least three active metallic gasket layers are disposed one above the other; beads being formed in at least two gasket layers around the through-opening(s); and a first bead-shaped, plastically deformable deformation limiter being disposed in a spacer sheet, which is disposed between these two gasket layers, on a side adjacent to the beads.
La présente invention concerne un joint en acier multicouche, par exemple un joint de culasse, comportant au moins une ouverture de passage (7, 7'), par exemple pour la chambre de combustion d'un moteur à combustion interne. Le joint selon l'invention comporte au moins trois couches d'étanchéité métalliques actives superposées (2, 2', 2''). Au moins deux couches d'étanchéité (2, 2'') comportent des collets (3, 3'') autour de la ou des ouvertures de passage. Par ailleurs, une tôle d'espacement (6) logée entre ces deux couches d'étanchéité comporte un premier limitateur de déformation (4) à déformation plastique, en forme de collet, sur un côté adjacent aux collets.
