Abstract

L'invention concerne des systèmes de ravitaillement en eau de divers réceptacles, en particulier, d'un réservoir de wagon passagers. Le dispositif de fermeture comprend un corps (1) pouvant se raccorder à un tuyau de remplissage d'eau, une soupape (5) raccordée à un flotteur (17), et un système de signalisation indiquant que le niveau d'eau nécessaire est atteint. Le dispositif de l'invention est caractérisé en ce que le corps comporte des orifices (13) communiquant avec sa cavité, et en ce que la soupape (5) est placée dans le corps de façon à pouvoir se déplacer entre les sièges d'appui et de butée. Afin d'éviter la pression de l'écoulement d'eau sur le flotteur (17) et sur ses éléments de raccordement, le flotteur (17) est raccordé à la partie supérieure de la tige de soupape, ladite tige étant conçue de sorte que l'eau puisse passer à travers celle-ci et se diriger vers le système de signalisation. En variante, afin d'assurer la stabilité de fonctionnement de la soupape, le flotteur (17) est relié à la tige de soupape par un mécanisme à levier.
