Title (DE) FÖRDERVORRICHTUNG FÜR DEN KRAFTSTOFF EINER VERBRENNUNGS-KRAFTMASCHINE
(EN) DELIVERY DEVICE FOR THE FUEL OF AN INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF DE TRANSPORT DU CARBURANT D'UN MOTEUR À COMBUSTION INTERNE
Abstract:
(DE) Eine Fördervorrichtung für den Kraftstoff einer Verbrennungs-Kraftmaschine, mit einem Kraftstofftank (4), aus dem zumindest eine Kraftstoffpumpe (14, 18) über eine Kraftstoff-Zulaufleitung (10) und mindestens einen Kraftstofffilter (12, 16) Kraftstoff an einen Kraftstoffabnehmer (2) fördert, der über eine Kraftstoff-Rücklaufleitung (20) mit dem Kraftstofftank (4) verbunden ist, ist dadurch gekennzeichnet, dass zwischen der Zulaufleitung (10) und der Rücklaufleitung (20) eine Steuereinrichtung (24) geschaltet ist, die bei Unterschreiten einer vorgebbaren Schwellentemperatur im Kraftstofftank (4) und bei einem vorgebbaren Schwellendruck in der Rücklaufleitung (20) eine kraftstoffführende Verbindung (80) zwischen der Rücklauf-(20) und der Zulaufleitung (10) herstellt.
(EN) The invention relates to a delivery device for the fuel of an internal combustion engine, having a fuel tank (4), from which at least one fuel pump (14, 18) conveys fuel to a fuel consumer (2) via a fuel supply line (10) and via at least one fuel filter (12, 16), said fuel consumer (2) being connected to the fuel tank (4) via a fuel return line (20), characterized in that a control apparatus (24) is connected between the supply line (10) and the return line (20), which, upon the temperature in the fuel tank (4) falling below a definable threshold and at a definable threshold pressure in the return line (20), establishes a fuel-delivering connection (80) between the return line (20) and the supply line (10).
(FR) L'invention concerne un dispositif de transport du carburant d'un moteur à combustion interne, comprenant un réservoir de carburant (4) à partir duquel au moins une pompe à carburant (14, 18) délivre du carburant par une conduite d'alimentation en carburant (10) et au moins un filtre à carburant (12, 16) à un collecteur de carburant (2), qui est relié au réservoir de carburant (4) par une conduite de retour de carburant (20), caractérisé en ce qu'un dispositif de commande (24) est connecté entre la conduite d'alimentation (10) et la conduite de retour (20), lequel dispositif de commande (24) établit une connexion de transport de carburant (80) entre la conduite de retour (20) et la conduite d'alimentation (10) lorsque la température du réservoir de carburant (4) descend en dessous d'une température seuil prédéterminée et lorsque la pression dans la conduite de retour (20) passe en dessous d'une pression seuil pouvant être prédéfinie.
