Abstract

Le tiroir se compose d'un carter (1a, 1b) pourvu d'une ouverture (5) de forme circulaire, qui peut etre obturée par une calotte (2) montée de façon pivotante dans le carter et dont une zone marginale dépassant du bord de l'ouverture (5) est rendue étanche par des disques annulaires d'étanchéité (9a, 9b, 9c) qui sont déplaçables au moyen d'un piston annulaire (11); pour obtenir un soulèvement sur des disques annulaires (9a, 9b, 9c) à partir de la calotte (2) avant son pivotement de la position de fermeture dans la position d'ouverture, les disques annulaires d'étanchéité (9a, 9b, 9c) sont liés rigidement au piston annulaire (11) qui est lui-meme entrainé par un cylindre de travail.
