Abstract

Dispositif permettant de diminuer les temps morts de montage et de raccordement en introduisant dans la chambre à essais la pièce à tester montée sur un chariot Avant, pendant et après les essais, le chariot 4 sur lequel est fixée la pièce à tester 5 est porté par des rouleaux 6, 7, 8. Il comporte un système de canalisation 12, un tube de raccordement 16 et des ouvertures 9, 14 pouvant être obturées (bouchon 15). Quand on abaisse le capot 2 sur la platine 3, le dispositif 21 appuie la pièce 5 sur le joint 11 et le tube 17 se raccorde au tube 16. Par la bride 20, on peut établir une dépression dans la chambre 1 et, par le tube 17, introduire un gaz témoin dans la pièce 5. S'il y a fuite, ce gaz est détecté au-delà de la bride 20.
