Abstract:
(EN) A stop cock for a liquid container, comprising a substantially annular valve housing, a circular valve rotatably mounted in the valve housing, a handle mounted on an operational shaft for rotating the valve between a closed and open position, a seat mounted in the valve housing and cooperating with the valve in the closed position, characterized in that the handle (21) comprises a recess (28) for rotatably receiving a stop bush (29) that comprises a cam (30) which in the closed position cooperates with an indentation (42) of a top plate (24) arranged on a boss (9) and includes a circular passage for the shaft (7), said stop bush (29) having a unround passage (33) for mounting a correspondingly formed driving shaft (34) of an unlocking lever (35), the handle (21) and the top plate (24) in a plurality of positions.
(FR) Soupape d'arrêt pour récipient à liquide, composée d'une chambre de soupape de forme quasi-annulaire, d'une soupape circulaire fixée de manière à pouvoir pivoter dans ladite chambre, d'une poignée montée sur une tige de commande pour faire pivoter la soupape entre position ouverte et position fermée, et d'un siège fixé dans la chambre de soupape qui fonctionne en association avec la soupape en position fermée. La poignée (21) comporte une cavité (28) qui abrite un manchon d'arrêt (29) muni d'une canne (30) qui, lorsque la soupape est en position fermée, fonctionne de pair avec une entaille (42) creusée dans un couvercle (24) posé sur une bosse (9). Ladite canne comprend en outre un pasage circulaire pour la tige (7), ledit manchon d'arrêt (29) ayant un passage non circulaire pour y installer l'arbre de commande de forme correspondante (34) d'un levier de déblocage (35), la poignée (21) et le couvercle (24), dans une pluralité de positions.
