Abstract

La chambre d'essai comporte un fond 2 relié à une pompe à vide 6 et à un détecteur de gaz d'essai 8; un capot 4 qui vient se poser sur le fond, avec interposition de garniture d'étanchéité 3, en entourant la pièce à éprouver. Ce capot 4 comporte un fourreau 15 qui vient s'abaisser sur l'ouverture 22 de la pièce à éprouver, mettant ainsi l'intérieur de cette pièce à éprouver en relation avec une source 19 de gaz d'essai et une source 20a de gaz sous pression, différent du gaz d'essai.
