Abstract
Die Kraftstoffversorgungseinrichtung weist ein elektromotorisch angetriebenes Förderaggregat (14) auf, durch das Kraftstoff aus einem Vorratsbehälter (12) zur Brennkaftmaschine (10) gefördert wird. In das Förderaggregat (14) sind ein Druckbegrenzungsventil (26) und ein Rückschlagventil (22) integriert. Stromabwärts des Förderaggregats (14) ist ein Kraftstoffilter (32) angeordnet und stromabwärts des Kraftstoffilters (32) ist ein Drucksensor (34) angeordnet. Der Drucksensor (34) ist mit einer Steuereinrichtung (36) verbunden, durch die der Betrieb des Förderaggregats (14) derart gesteuert wird, daß der Kraftstoffdruck zumindest annähernd gleich einem Solldruck ist. Stromabwärts des Drucksensors (34) ist ein gedrosselter Ablauf (42) vorgesehen, der durch eine Ventileinrichtung (40) druckabhängig derart gesteuert wird, daß der Ablauf (42) bei Überschreiten eines etwas unterhalb des Solldrucks liegenden Kraftstoffdrucks öffnet. An den Ablauf (42) ist wenigstens eine Saugstrahlpumpe (29) angeschlossen. The fuel supply device has a delivery unit (14) driven by an electric motor, through which fuel is delivered from a storage container (12) to the internal combustion engine (10). A pressure limiting valve (26) and a check valve (22) are integrated in the delivery unit (14). A fuel filter (32) is arranged downstream of the delivery unit (14) and a pressure sensor (34) is arranged downstream of the fuel filter (32). The pressure sensor (34) is connected to a control device (36) by means of which the operation of the delivery unit (14) is controlled in such a way that the fuel pressure is at least approximately equal to a target pressure. A throttled outlet (42) is provided downstream of the pressure sensor (34) and is controlled in a pressure-dependent manner by a valve device (40) in such a way that the outlet (42) opens when a fuel pressure slightly below the target pressure is exceeded. At least one suction jet pump (29) is connected to the outlet (42).
