Abstract

L'invention a pour objet un compteur de gaz (1) à membranes à entra*nement de distribution rotatif comprenant plusieurs chambres de mesure, et un élément de distribution (2) monté rotatif sur la surface supérieure d'un couvercle de distribution dans lequel sont ménagées plusieurs ouvertures qui sont reliées chacune à une chambre de mesure, l'élément de distribution (2) permettant au gaz d'entrer et de sortir alternativement des chambres de mesure au cours de son mouvement de rotation, que le compteur (1) comprenant en outre au moins un élément anti-retour (8) solidaire, via une zone de solidarisation (11), d'une structure support (7) fixe disposée au-dessus de l'élément de distribution (2), chaque élément anti-retour (8) coopérant avec des moyens bloquants (9, 16) de l'élément de distribution (2), de façon à autoriser la rotation de l'élément de distribution (2) dans un sens, dit sens de fonctionnement, et à bloquer l'élément de distribution (2) lors de sa rotation en sens inverse, chaque élément anti-retour (8) étant en outre apte à prendre appui sur l'élément de distribution (2) lors de sa rotation en sens inverse, de façon à empêcher un soulèvement de l'élément de distribution (2) sous l'action de la pression du gaz.
