Abstract
Sitzventil, insbesondere für ein elektromagnetisch betätigtes Sitzventil in einem Kraftfahrzeug-Radschlupfregelsystem, in dessen Ventilgehäuse ein als Ventilschließglied wirksamer Ventilstößel beweglich geführt ist, der mittels einer Zentrierhülse auf einen Ventilsitzkörper gerichtet ist, dadurch gekennzeichnet, daß die Zentrierhülse (10) gelenkig am Ventilsitzkörper (8) befestigt ist.Seat valve, in particular for an electromagnetically actuated seat valve in a motor vehicle wheel slip control system, in the valve housing of which a valve tappet, which acts as a valve closing member and which is directed by means of a centering sleeve onto a valve seat body, is movably guided, characterized in that the centering sleeve (10) is articulated on the valve seat body (8 ) is attached.
Description
Die Erfindung betrifft ein Sitzventil, insbesondere ein elektromagnetisch betätigtes Sitzventil in einem Kraftfahrzeug-Radschlupfregelsystem, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a seat valve, in particular an electromagnetically actuated seat valve in a motor vehicle wheel slip control system, according to the preamble of patent claim 1.
Aus der
Das zwischen dem Ventilstößel und der Zentrierhülse erforderliche kleinste Radialspiel wird durch die Exzentrizität der Dichtkante am Ventilstößel gegenüber dem Außendurchmesser des Hohlzylinders als auch durch die Exzentrizität der Zentrierbohrung in der Zentrierhülse gegenüber der Befestigung der Zentrierhülse am Außendurchmesser des Hohlzylinders beeinflußt. Hierdurch ergibt sich die Notwendigkeit und der Nachteil, daß das zur Selbstzentrierung des Ventilstößels erforderliche minimale Radialspiel in der Regel groß zu wählen ist. Mit zunehmenden Radialspiel in der Zentrierhülse nimmt aber das Ventilgeräusch zu, das auf der am Magnetanker wirksamen Querkraft beruht, die während einer elektromagnetischen Erregung zu unerwünschtem Ankerversatz und damit zu unerwünschtem Körperschall führt.The minimum radial clearance required between the valve stem and the centering sleeve is influenced by the eccentricity of the sealing edge on the valve stem relative to the outer diameter of the hollow cylinder as well as by the eccentricity of the center hole in the centering sleeve relative to the attachment of the centering on the outer diameter of the hollow cylinder. This results in the necessity and the disadvantage that the required for self-centering of the valve stem minimum radial clearance is usually large. However, as the radial play in the centering sleeve increases, the valve noise increases, which is based on the lateral force acting on the magnet armature, which leads to undesired armature offset and thus to undesired structure-borne noise during electromagnetic excitation.
Daher ist es die Aufgabe der vorliegenden Erfindung, ein Sitzventil der gattungsbildenden Art unter Beibehaltung eines möglichst einfachen Aufbaus derart zu verbessern, daß vorgenannte Nachteile vermieden werden, wozu das minimale Radialspiel in der Zentrierhülse zu verkleinern ist.Therefore, it is the object of the present invention to improve a seat valve of the generic type while maintaining the simplest possible structure such that the aforementioned disadvantages are avoided, including the minimum radial clearance in the centering sleeve is to be reduced.
Diese Aufgabe wird erfindungsgemäß für ein Sitzventil der angegebenen Art mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved for a seat valve of the type indicated with the features of claim 1.
Weitere Merkmale und Vorteile der Erfindung werden im Nachfolgenden anhand der Beschreibung eines Ausführungsbeispiels erläutert.Further features and advantages of the invention will be explained below with reference to the description of an embodiment.
