Abstract

L'invention concerne une unité de transport de carburant composée d'un pot de compensation 1, d'un filtre fin 7 disposé dans ce pot et d'une pompe à jet aspirant 4 pour remplir le pot de compensation 1, le pot de compensation 1 possédant une ouverture 3 dans le fond et cette ouverture 2 étant recouverte par la partie aspirante 5 de la pompe à jet aspirant 4. La pompe à jet aspirant 4 présente un raccord de fluide moteur 18 qui est relié au fond 9 du boîtier 8 du filtre fin de telle manière que le carburant situé dans la partie inférieure du filtre fin 7 passe directement dans le raccord de fluide moteur 18 de la pompe à jet aspirant 4.
