Abstract

Procédé de détection de fuite d'une pièce creuse comprenant les étapes consistant à sceller ladite pièce creuse (1, 31), à créer une différence de pressions P1 et P2 entre l'intérieur de ladite pièce creuse et un compartiment adjacent (2, 32) ou une enceinte, à mettre un gaz traceur dans l'un parmi la pièce creuse et ledit compartiment ou ladite enceinte, à attendre un temps d'enrichissement T puis à effectuer une étape consistant à transférer via une restriction non sélective ou sélective (6, 7 ; 49) le contenu de ladite pièce creuse ou dudit compartiment ou de ladite enceinte (2, 32) où n'a pas été mis de gaz traceur de façon à concentrer dans un volume en aval de ladite restriction (6, 7 ; 49) le gaz traceur que ledit contenu contient éventuellement, puis à rechercher la présence de gaz traceur dans ledit volume. Installation pour la mise en oeuvre du procédé.
