Abstract

La présente invention a pour objet un compteur de liquide, caracterisé en ce qu'il comprend deux paires de chambres à volume variable 3a-3'a-3b-3'b comportant chacune une paroi mobile 2a ou 2b, un clapet d'admission relié à une conduite d'admission et un clapet d'échappement relié à une conduite d'échappement, la conduite d'admission et la conduite d'échappement étant communes à toutes les chambres, les parois mobiles des chambres d'une même paire étant solidaires l'une de l'autre ou confondues, de sorte que lorsque l'une des chambres de la paroi a son volume maximal, l'autre chambre a son volume minimal, et des moyens commandés par l'arrivée en fin de course de la ou des parois mobiles de chaque paire de chambres pour commuter la position des clapets des chambres de l'autre paire de façon qu'a tout moment le clapet d'admission de l'une des chambres de cette autre paire soit fermé alors que son clapet d'échappement est ouvert, et que le clapet d'admission de l'autre chambre de cette même paire soit ouvert alors que son clapet d'échappement est fermé.
