Description
Die Steuerung der Leistungszufuhr erfolgt über einen Pulsweitenmodulator, d. h. es liegt keine Pumpenabschaltung vor.
ein erfindungsgemäßen Brennstoffversorgungssystem,
eine Ausbildung des Druckschalters aus Fig. 1.
Claims (2)
- Brennstoffversorgungssystem für Brennkraftmaschinen, gebildet aus Brennstoffpumpe (1), Druckschalter (4) und Verteilerleiste/Anschlüssen für Einspritzventile, wobei der Druckschalter (4) die Leistungszufuhr zur Brennstoffpumpe (1) in Abhängigkeit vom Pumpendruck steuert und stromab des Druckschalters (4) zusätzlich ein Reduzierdruckregler (5) eingesetzt ist, dessen Reduzierdruck niedriger als der vom Druckschalter (4) geregelte Druck ist,
dadurch gekennzeichnet,
daß der Druckschalter (4) mit einem Speichervolumen (12) ausgestattet ist, das durch eine Membrane/einen Kolben (11) begrenzt ist, die/der im Zusammenhang mit einer Stange (10) mit zwei Anschlagflächen (16, 17) eine Öffnung von Schaltkontakten (8) bei großem gespeicherten Brennstoffvolumen und deren Schließung bei kleinem bewirkt. - System nach Anspruch 1,
dadurch gekennzeichnet,
daß das Speichervolumen (12) bei abgestellter Brennkraftmaschine durch ein Brennstoffabschaltventil (19) verschlossen ist.
