Abstract

La présente invention se rapporte à un siphon de sol auto-obturant comprenant: un corps d'évacuation (1) monté dans un tuyau d'évacuation de l'égout ou dans un siphon de sol classique en forme de cloche, et un élément d'obturation élastique (13) monté mobile dans l'orifice de sortie d'eau du corps d'évacuation (1). Ce dernier se présente sous la forme d'un cylindre circulaire creux et comprend une enveloppe (11). Un élément d'ouverture/de fermeture est monté sur la paroi interne de ladite enveloppe du corps d'évacuation, un ressort de torsion (136) étant monté dans ledit élément d'ouverture/de fermeture (12) en vue d'ouvrir et de refermer l'élément d'obturation élastique (13). Ce dernier est déplacé vers le bas par le poids des eaux usées pour ouvrir la partie d'obturation et les eaux usées s'écoulent dans le tuyau d'évacuation, après quoi la partie d'obturation est fermée par le ressort de torsion (136) de manière à éviter les eaux usées à l'état barotrope, les odeurs nauséabondes, les gaz toxiques et les nuisibles. Cet appareil est simple, pratique, stable et sûr. Les eaux usées peuvent être librement évacuées et le coût en est réduit.
