Abstract

L’invention a pour objet un système de proctoclyse à clapet de non retour pourvu d’une tige de guidage. Un entonnoir membranaire (4) recouvre la paroi interne cylindrique du purgeur et un corps de clapet (3) est placé entre la membrane (4) et l’orifice d’entrée (1) du système. Le corps de clapet (3) porte une tige de guidage (6) dont l’extrémité libre traverse l’ouverture de l’entonnoir membranaire (5) et est reliée au flotteur creux (7). Le flotteur (7) présente une cavité (8) lestée ou non d’un poids (9). La surface de contact fermée du corps de clapet (3) et de l’entonnoir membranaire (4) est sinueuse ou plane.
