A sphincter valve has a membrane (10) formed with at least one slit (12) defined by petals, which membrane (10) adopts a convex dished configuration when the valve is closed and inverts into a concave configuration when the valve is opened. In the invention, an abutment member (16) is movable relative to the membrane (10) for opening the valve by making direct contact with the petals to open the slit between the petals.
La présente invention concerne une vanne antireflux qui comporte une membrane (10) formée avec au moins une fente (12) définie par des pétales. Ladite membrane (10) adopte une configuration de disque convexe lorsque la vanne est fermée et s'inverse en une configuration concave lorsque la vanne est ouverte. Dans l'invention, un élément de butée (16) est mobile par rapport à la membrane (10) pour ouvrir la vanne en établissant un contact direct avec les pétales afin d'ouvrir la fente entre les pétales.
