Title (EN) CYLINDER HEAD GASKET HAVING A DEGASSING OPENING
(FR) JOINT DE CULASSE PRÉSENTANT UNE OUVERTURE DE DÉGAZAGE
Abstract:
(EN) The invention relates to a cylinder head gasket intended for being inserted between a cylinder casing and a cylinder head of an engine block which is provided with a coolant circulation circuit, including at least one plate (10, 11, 12) crossed by: at least one wide opening, suitable for being aligned with a cylinder bore of a cylinder casing; and at least one small opening, referred to as degassing opening (21), suitable for being aligned with a degassing pipe of said circulation circuit. According to the invention, the cylinder head gasket includes a membrane (30) which seals said degassing opening, with a porosity strictly higher than the porosity of said at least one plate.
(FR) L'invention concerne un joint de culasse à interposer entre un carter- cylindres et une culasse d'un bloc-moteur qui est équipé d'un circuit de circulation d'un liquide de refroidissement, comportant au moins une plaque (10, 11, 12) traversée par: -au moins une large ouverture adaptée à venir en correspondance avec un alésage de cylindre du carter-cylindres, et -au moins une petite ouverture, dite ouverture de dégazage (21), adaptée à venir en correspondance avec un conduit de dégazage dudit circuit de circulation. Selon l'invention, le joint de culasse comporte une membrane (30) qui obture ladite ouverture de dégazage et dont la porosité est strictement supérieure à la porosité de ladite au moins une plaque.
