Abstract

Un dispositif de remplissage pour réservoir de toilettes empêche l'écoulement continuel vers le réservoir, en cas de fuite dudit réservoir, en fournissant une soupape de sûreté hydraulique pour arrêter l'écoulement de l'eau vers le robinet de remplissage, si ledit écoulement se poursuit au- delà de la durée de remplissage prévue. La soupape de sûreté comprend un élément de soupape raccordé à un piston monté dans un cylindre déterminant une première chambre d'un côté du piston, et une seconde chambre, de l'autre côté. Un dispositif venturi dans le conduit d'approvisionnement fournit dans une chambre basse pression du dispositif venturi une pression d'eau inférieure à la pression dans le conduit d'approvisionnement. Ainsi, la différence de pression à travers le piston, causée par la différence de pression entre la pression d'alimentation et la chambre à basse pression produit le déplacement du piston, de la première extrémité vers la seconde extrémité. Un orifice régule le débit de l'eau, de sorte que la durée de déplacement du piston soit supérieure à la durée prévue requise pour remplir le réservoir de toilettes. Un ressort sollicite le piston pour qu'il revienne à la première extrémité, après remplissage du réservoir de toilettes.
