The invention relates to a gas quenching method of the type that makes use of (i) a quenching cell (V1) which is intended to receive objects to be quenched with a quenching gas and (ii) a buffer capacity (V2) which is designed to contain the quenching gas. The invention is characterised in that following a quenching operation, all or part of the gas contained in the cell (V1) is recycled in the following manner consisting in: obtaining a first intermediate storage balloon (V3) which can receive the quenching gas from the cell; after a quenching operation, performing one or more operations comprising the partial emptying of the contents of the cell (V1) into the first intermediate storage balloon (V3), by means of partial or total pressure balancing between the two volumes of the cell (V1) and the first intermediate storage balloon; transferring the gas stored in the first intermediate storage balloon (V3) to the buffer capacity (V2); and, if necessary, releasing part of the contents of the cell (V1) into the atmosphere.

Un procédé de trempe par gaz, du type où l'on dispose d'une cellule de trempe (V1) destinée à recevoir des objets à tremper à l'aide d'un gaz de trempe, et où l'on dispose d'une capacité tampon (V2) adaptée pour contenir du gaz de trempe, caractérisé en ce que l'on procède, après une opération de trempe, au recyclage de tout ou partie du gaz contenu dans la cellule (V1) de la façon suivante - on dispose d'un premier ballon de stockage intermédiaire (V3) apte à recevoir du gaz de trempe en provenance de la cellule ; on procède, après une opération de trempe, à une ou plusieurs opérations de vidange partielle du contenu de la cellule (V1) dans le premier ballon de stockage intermédiaire (V3) par un équilibrage de pression partiel ou complet entre les deux volumes de la cellule (V1) et du premier ballon de stockage intermédiaire ; - on procède au transfert du gaz stocké dans ledit premier ballon de stockaae intermédiaire (V3) vers la capacité tampon (V2); - on rejète le cas échéant une partie du contenu de la cellule (V1) à l'air libre.
