Claims (6)
- Ventilanordnung zur Druckregelung der Kraftstoffzufuhr bei einer Brennkraftmaschine mit zumindest einer Druckregeleinrichtung und einer durch einen elektromagnetischen Antrieb betätigbaren Absperreinrichtung, dadurch gekennzeichnet, daß ein Gehäuse (19) vorgesehen ist mit zumindest einem Einlaßanschlußstück (11, 25, 26) und zumindest einem Auslaßanschlußstück (12,27,28), die über einen Verbindungskanal (13) fluidisch miteinander verbunden sind, wobei der elektromagnetischer Antrieb (16) mittels eines Ankers (21) auf einen Stößel (15) mit einem Schließelement (14) wirkt, das den Verbindungskanal öffnet oder schließt, und mit zumindest einem Druckfederelement (22, 29,30), das direkt oder indirekt in Schließrichtung auf das Schließelement (14) wirkt.
- Ventilanordnung nach Anspruch 1, dadurch gekennzeichnet, daß die Magnetkraft auf den Anker (21) in Schließrichtung des Schließelementes (14) wirkt, wobei desweiteren eine Druckfeder (22), die sich an einem Gehäuseteil (23) abstützt, in Schließrichtung auf den Anker (21) wirkt.
- Ventilanordnung nach Anspruch 1, dadurch gekennzeichnet, daß die Magnetkraft auf den Anker (21) gegen die Schließrichtung des Schließelementes (14) wirkt, wobei eine erste Druckfeder (29) in Schließrichtung auf den Anker (21) wirkt und eine zweite Druckfeder (30) in Schließrichtung auf den Stößel (15) wirkt und sich beide Druckfedern (29, 30) an Gehäuseteilen (20, 23) abstützen.
- Ventilanordnung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß das Gehäuse (19) zwei Einlaßanschlußstücke (25, 26) und zwei Auslaßanschlußstücke (27, 28) aufweist.
- Ventilanordnung nach einem der Ansprüche 2-4, dadurch gekennzeichnet, daß das Gehäuse (19) einen in Schließrichtung bewegbaren Ankerkern (23) aufweist, an dem sich die auf den Anker (21) wirkende Druckfeder (22, 29) abstützt.
- Ventilanordnung nach Anspruch 5, dadurch gekennzeichnet, daß der elektromagnetische Antrieb (14) ein Proportional-Magnetsystem aufweist, wobei der Ankerkern (23) eine elliptische Außenkontur besitzt.
