Abstract

L’invention a pour objet un clapet anti-siphon bidirectionnel (11) comprenant un conduit principal (12) équipé d’un organe d’obturation mobile dans une plage de déplacement (PD) qui comprend consécutivement une première plage d’ouverture (P1), une plage de fermeture (P0) et une deuxième plage d’ouverture (P2), pour laisser passer un fluide dans une premier sens lorsque l’organe d’obturation est dans la première plage d’ouverture (P1) et dans un deuxième sens lorsque l’organe d’obturation est dans la deuxième plage d’ouverture (P2), et des moyens de rappel (16) tendant continuellement à ramener l’organe d’obturation à une position médiane située dans la plage de fermeture (P0) de manière à permettre l’ouverture seulement lorsque l’organe d’obturation est soumis à un écart de pression supérieur à une valeur seuil.
