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.The drawer consists of a casing (1a, 1b) provided with an opening (5) of circular shape, which can be closed by a cap (2) pivotally mounted in the casing and of which a marginal zone protruding from the edge the opening (5) is sealed by annular sealing discs (9a, 9b, 9c) which are displaceable by means of an annular piston (11); to obtain a lifting on annular discs (9a, 9b, 9c) from the cap (2) before its pivoting from the closed position to the open position, the annular sealing discs (9a, 9b, 9c ) are rigidly connected to the annular piston (11) which is itself driven by a working cylinder.
