Title
(EN) A CIRCULATING FUEL SUPPLY SYSTEM FOR A COMMERCIAL MOTOR VEHICLE
(FR) SYSTÈME D'ALIMENTATION EN CARBURANT CIRCULANT POUR UN VÉHICULE À MOTEUR COMMERCIAL
Abstract
(EN)
A circulating fuel supply system for a commercial motor vehicle comprising a fuel storage tank having a top wall and a bottom wall opposite the top wall. A draw conduit extends into the fuel storage tank from the top wall to the bottom wall. An inlet for fuel is only provided in a lower end of the draw conduit and is spaced above the bottom wall. A first buoyant float body is positioned vertical movably around the first draw conduit for closing or opening the inlet for fuel in dependence of liquid fuel level in the fuel storage tank. The fuel supply system further comprises a return conduit extending into the fuel storage tank from the top wall to the bottom wall, said return conduit has a lower end positioned adjacent the bottom wall of the fuel storage tank, and an outlet for return fuel is included only in an upper end of the return conduit. A second buoyant float body is positioned vertical movably around the return conduit for closing or opening the outlet for return fuel in dependence of liquid fuel level in the fuel storage tank.
(FR)
La présente invention concerne un système d'alimentation en carburant circulant pour un véhicule à moteur commercial comprenant un réservoir de stockage de carburant pourvu d'une paroi supérieure et d'une paroi inférieure opposée à la paroi supérieure. Un conduit d'aspiration s'étend dans le réservoir de stockage de carburant depuis la paroi supérieure jusqu'à la paroi inférieure. Une entrée de carburant est exclusivement disposée dans une extrémité inférieure du conduit d'aspiration et elle est espacée au-dessus de la paroi inférieure. Un premier corps flottant est positionné verticalement de façon mobile autour du premier conduit d'aspiration pour fermer ou ouvrir l'admission de carburant en fonction du niveau de carburant liquide présent dans le réservoir de stockage de carburant. Le système d'alimentation en carburant comprend en outre un conduit de retour s'étendant dans le réservoir de stockage de carburant depuis la paroi supérieure jusqu'à la paroi inférieure. Ledit conduit de retour a une extrémité inférieure adjacente à la paroi inférieure du réservoir de stockage de carburant, et une sortie pour le carburant de retour est exclusivement incluse dans une extrémité supérieure du conduit de retour. Un second corps flottant est positionné verticalement de façon mobile autour du conduit de retour pour fermer ou ouvrir la sortie du carburant de retour en fonction du niveau de carburant liquide dans le réservoir de stockage de carburant.
