Abstract

L'invention concerne objet un ensemble filtre pour automobiles au GPL, ayant d'une fonction antiretour. Généralement, il est possible d'éliminer des impuretés dans le GPL, mais due au nombre élevé de pièces, il existent des problèmes de coûts de fabrication élevés et de procédé de fabrication est compliqué, puisque le clapet antiretour empêchant le retour du GPL et le filtre permettant d'éliminer les impuretés sont fabriqués séparément. Pour remédier aux problèmes susmentionnés, la présente invention concerne un ensemble filtre pour automobiles au GPL qui comporte une fonction antiretour. Cet ensemble comprend un filtre, qui filtre des impuretés contenues dans le GPL et qui est formé en une seule pièce avec un clapet antiretour intégré, empêchant le retour du GPL. Cette fonction permet de simplifier le procédé de fabrication en réduisant le nombre de pièces, et ainsi réaliser une économie des coûts.
