Abstract

La présente invention a pour objet un dispositif d'évaporation (13) des vapeurs d'un carburant stocké dans un réservoir (12) de véhicule automobile. Le dispositif d'évaporation (13) comprend un circuit de dérivation (138) et une vanne de dérivation (139) configurée pour évoluer entre une position dite « d'absorption », dans laquelle la vanne de dérivation (139) permet la circulation des gaz entre le réservoir (12) et un filtre absorbant (131) et une position dite « de détection de fuite », dans laquelle la vanne de dérivation (139) permet la circulation des gaz entre un circuit de purge (133) et le réservoir (12) via le circuit de dérivation (138).
