Abstract
(DE)
Die Erfindung betrifft eine Einrichtung zum Fördern von Kraftstoff aus einem Vorratstopf (12) zur Brennkraftmaschine (18) eines Kraftfahrzeuges, mit einem saugseitig mit dem Vorratstopf (12) und druckseitig mit der Brennkraftmaschine (18) verbundenen Förderaggregat (14) und einer Rückführleitung (22), die zu einer nahe einem Tankboden (11) angeordneten Strahlpumpe (24) führt, die den Kraftstoffüberschuß über einen Mischbereich (29) in einen Vorratstopf (12) fördert, aus welchem das Förderaggregat (14) Kraftstoff entnimmt, wobei zwischen dem Vorratstopf (12) und dem Tankboden (11) ein siphonartig ausgebildeter Mischbereich (29) vorgesehen ist, der im Übergangsbereich (31) zum Vorratstopf (12) eine Öffnung (32) aufweist, die mit einem Schließelement (44) verschließbar ist.
(EN)
The invention concerns a device for feeding fuel from a feed reservoir (12) to the combustion engine (18) of an automobile, the device having a feed unit (14) connected on the aspiration side to the feed reservoir (12) and on the delivery side to the engine (18), the device also having a return line (22) which leads to a jet pump (24) which is located near the floor (11) of the fuel tank and which pumps excess fuel through a mixing zone (29) into the reservoir (12) from where the feed unit (14) takes its fuel. The siphon-like mixing zone (29) is located between the reservoir (12) and the tank floor (11) and has, at the point (31) where it leads into the reservoir (12), an aperture (32) which can be closed off by a closure element (44).
(FR)
L'invention concerne un dispositif servant à amener du carburant depuis une réserve (10) jusqu'au moteur à combustion interne (18) d'une automobile, le dispositif comprenant une unité d'alimentation (14) reliée, du côté aspiration, à la réserve (12) et, du côté refoulement, au moteur (18). Ledit dispositif comporte également un conduite de retour (22) qui conduit jusqu'à une pompe à jet (24) qui est située à proximité du fond du réservoir à carburant et qui pompe le carburant en excès pour l'introduire, par l'intermédiaire d'une zone de mélange (29), dans la réserve (12) d'où l'unité d'alimentation (14) prélève le carburant. La zone de mélange (29) conçue comme un siphon est située entre la réserve (12) et le fond (11) du réservoir et elle présente, dans sa zone de transition (31) avec la réserve (12), une ouverture (32) qui peut être fermée par un élément d'obturation (44).
