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.
