Description
Claims (5)
einem Magnetventil (64b, 100, 110), das zwischen beiden Strömungsverbindungen angeordnet ist, wobei das Steuerventil bei geschlossenem Magnetventil eine Strömung von der ersten Strömungsverbindung (66a) in die zweite Strömungsverbindung (50d) verhindert, wenn der Strömungsmitteldruck in der ersten Strömungsverbindung (66a) höher ist als in der zweiten Strömungsverbindung (50d), jedoch ein Durchströmen von Bremsfluid erlaubt, wenn der Strömungsmitteldruck in der ersten Strömungsverbindung (66a) niedriger ist als der Druck in der zweiten Strömungsverbindung (50d), und mit
einem Anker (100) aus ferromagnetischem Material, der bei Betätigung einer Magnetspule (64b) axial verschiebbar ist und an seinem einen Ende eine Ventilkugel (108) aufweist,
einem Einsatz (110) mit einem zentralen, axial verlaufenden Kanal (110c, 110d), der die erste und zweite Strömungsverbindung (66a, 50d) miteinander verbindet und mit seinem einen Ende an einen Ventilsitz (110a) angrenzt, der mit der Ventilkugel (108) zusammenwirkt, um den Kanal (110c, 110d) zu schließen, wobei der Anker (100) koaxial zu dem Kanal (110c, 110d) verläuft und außerhalb des Kanals angeordnet ist,
einem Dichtring (111), der in einer umlaufenden Nut des Einsatzes (110) angeordnet ist,
einem an einem Ende offenen Gehäusehohlraum (54), in den der Einsatz (110) mit dem Dichtring (111) eingesetzt ist und der einen den Einsatz umgebenden Ringwandabschnitt (54e) aufweist, der mit dem Dichtring (111) zusammenwirkt,
wobei der Dichtring (111) bei Beaufschlagung mit Bremsdruck ein Durchströmen von Bremsfluid zwischen dem Einsatz (110) und dem Ringwandabschnitt (54e) in der einen Richtung vom größeren hin zum kleineren Druckniveau verhindert, während in der entgegengesetzten Richtung Bremsfluid an dem Dichtring (111) überströmen kann, wenn der größere Druck auf der entgegengesetzten Seite anliegt.
