Abstract

L'invention concerne un réservoir de carburant (160, 160') d'un véhicule (100). Le réservoir de carburant (160, 160') comprend une chambre (157, 157') de carburant conçue pour contenir du carburant. Le réservoir de carburant (160, 160') comprend également une première paroi (161, 161') enfermant au moins une partie de la chambre (157, 157') de carburant. La première paroi (161, 161') comprend une ouverture (159, 159') de réservoir de carburant définissant un premier axe (X-X', X''-X'''). Le réservoir de carburant (160, 160') comprend en outre une unité de remplissage (175, 175') de carburant s'étendant de l'ouverture (159, 159') de réservoir de carburant de la première paroi (161, 161') dans la chambre (157, 157') de carburant. Au moins une partie de l'unité de remplissage (175, 175') de carburant définit un second axe (Y-Y', Y''-Y'''). Le second axe (Y-Y', Y''-Y''') coupe le premier axe (X-X', X''-X''') à un angle (α, α 1).
