Abstract

Dispositif de contrôle des émissions de vapeurs de carburant, comportant : - un filtre absorbant (10) ; - un circuit de purge (15) comportant : une pompe (11) munie d’une entrée d’aspiration (21) et d’une sortie de refoulement (27) ; une conduite amont (16) ; une conduite aval (17). La pompe (11) comporte une chambre d’aspiration (20) dans laquelle débouche l’entrée d’aspiration (21). La conduite amont (16) est reliée par l’une de ses extrémités au filtre absorbant (10) et débouche par l’autre de ses extrémités dans la chambre d’aspiration (20). La conduite aval (17) comporte une double paroi tubulaire (23, 24) définissant deux canaux (25, 26) séparés. Figure pour l’abrégé : Fig. 1
