Abstract

Das Druckregelventil dient zur Regelung des Druckes in einem Kraftstoffspeicher und weist einen Ventilkörper auf, in dem in einer Bohrung (26) ein kolbenförmiges Ventilglied (28) gegen die Kraft einer Schließfeder (36) axial verschiebbar angeordnet ist. Das Ventilglied (28) bildet einen Anker eines Elektromagneten, der zur Unterstützung der Schließkraft der Schließfeder bestrombar ist. Das Ventilglied (28) wirkt auf ein Schließelement, das durch die Kraft der Schließfeder und die magnetische Kraft gegen einen Ventilsitz gepresst wird und das andererseits vom Druck im Kraftstoffspeicher beaufschlagt ist. Das Ventilglied (28) weist zwei in axialer Richtung zueinander versetzt angeordnete Führungsabschnitte (54) auf, die als kurze Zylinderabschnitte ausgebildet sind und einen Durchmessen aufweisen, der nur wenig kleiner ist als der Durchmesser der Bohrung (26). Über seine Führungsabschnitte (54) ist das Ventilglied (28) in der Bohrung (26) mit definierter Anlage verschiebbar geführt.
