Abstract
Die Erfindung betrifft ein Elektromagnetventil, dessen zwischen einem Ventilsitz (11) und einem Magnetanker (3) angeordneter Ventilraum (1) über einen den Magnetanker (3) durchdringenden Druckausgleichskanal (4) mit einem Zwischenraum (2) permanent hydraulisch verbunden ist, der vom Magnetanker (3) und einem Magnetkern (12) begrenzt ist, um eine vollständige Entlüftung und hydraulische Befüllung des Zwischenraums (2) zu gewährleisten.The invention relates to a solenoid valve whose valve space (1) arranged between a valve seat (11) and a magnet armature (3) is permanently hydraulically connected to an intermediate space (2) via a pressure equalization channel (4) penetrating the armature (3) (3) and a magnetic core (12) is limited to ensure complete ventilation and hydraulic filling of the gap (2).
Description
Die Erfindung betrifft ein Elektromagnetventil, insbesondere für hydraulische Kraftfahrzeugbremsanlagen, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a solenoid valve, in particular for hydraulic motor vehicle brake systems, according to the preamble of patent claim 1.
Aus der
Das vorgestellte Elektromagnetventil hat somit den Nachteil, dass bei einer ungenügenden Entlüftung des Zwischenraums während einer elektromagnetischen Erregung ein unerwünschtes Anschlaggeräusch des Magnetankers am Magnetkern entsteht.The presented solenoid valve thus has the disadvantage that, with insufficient ventilation of the gap during electromagnetic excitation unwanted impact noise of the magnet armature arises at the magnetic core.
Daher ist es die Aufgabe der vorliegenden Erfindung, ein Elektromagnetventil der angegebenen Art mit möglichst einfachen, funktionsgerechten Mitteln kostengünstig und klein-bauend derart zu verbessern, dass unter Beibehaltung kleinster Lauftoleranzen des Magnetankers im Ventilgehäuse das vorgenannten Ventilschaltgeräusch nicht auftritt.Therefore, it is the object of the present invention, a solenoid valve of the specified type with the simplest possible, functionally appropriate means cost and small-scale to improve such that while maintaining the smallest running tolerances of the armature in the valve housing, the aforementioned valve switching noise does not occur.
Diese Aufgabe wird erfindungsgemäß für das Elektromagnetventil der angegebenen Art durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved according to the invention for the solenoid valve of the type indicated by the features of claim 1.
Weitere Merkmale und Vorteile der Erfindung gehen im Nachfolgenden aus der Beschreibung eines Ausführungsbeispieles hervor.Further features and advantages of the invention will become apparent in the following from the description of an embodiment.
