Abstract

Dispositif comportant un flotteur en forme d'oeuf. L'appareil 10 comporte un flotteur 18 situé dans un boîtier 12 fermé par un couvercle 36. Le flotteur est guidé en haut par une tige 24 traversant l'ouverture d'entrée 14 et en bas par une tige 30 passant dans le canal 32 de liaison avec la sortie 16. Le flotteur 18 porte un appendice hémisphérique 26 qui coopère avec un arrondi du boîtier 12 pour ouvrir et fermer le canal 32. Quand le flotteur monte en présence de liquide, le collet conique 22 peut fermer l'ouverture 14.
