Abstract
Die Erfindung betrifft ein Elektromagnetventil, welches zum Verbinden oder Trennen von Druckmittelkanälen in einem Ventilgehäuse (4) einen mit einem Magnetanker (1) zusammenwirkenden Ventilstößel (2) aufweist, der im Ventilgehäuse (4) auf einen Ventilsitz (6) gerichtet ist, sowie mit einer zur Betätigung des Magnetankers (1) vorgesehenen Magnetspule. Zwischen dem Magnetanker (1) und dem Ventilstößel (2) ist ein aus einem austenitischen Werkstoff bestehendes Distanzstück (3) angeordnet, um einen Magnetfluss vom Magnetanker (1) auf den Ventilstößel (2) zu verhindern, der zur Verschleißminderung bevorzugt aus einem gehärteten, den Magnetfluss leitenden Material besteht.The invention relates to an electromagnetic valve which, for connecting or disconnecting pressure medium ducts in a valve housing (4), has a valve tappet (2) which interacts with a magnet armature (1) and which is directed towards a valve seat (6) in the valve housing (4) and with a magnet coil provided for actuating the armature (1). A spacer (3) made of an austenitic material is arranged between the magnet armature (1) and the valve tappet (2) in order to prevent magnetic flux from the magnet armature (1) to the valve tappet (2). material that conducts the magnetic flux.
Description
Die Erfindung betrifft ein Elektromagnetventil nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an electromagnetic valve according to the preamble of
Aus der
Das oben erwähnte Elektromagnetventil hat jedoch den Nachteil, dass im Falle einer Verwendung eines gehärteten, den Magnetfluss leitenden Ventilstößels zwangsläufig im Sinne eines magnetischen Kurzschlusses ein unerwünschter Magnetfluss vom Magnetanker auf den Ventilstößel entsteht, weshalb zur Vermeidung eines magnetischen Kurzschlusses der Ventilstößel aus einem den Magnetfluss nicht leitenden Material herzustellen ist, was in der Regel zur Verwendung von Werkstoffen führt, die keine hohe und damit dauerhafte Verschleißfestigkeit aufweisen.However, the above-mentioned electromagnetic valve has the disadvantage that if a hardened valve tappet that conducts the magnetic flux is used, an undesired magnetic flux inevitably arises from the magnet armature to the valve tappet in the sense of a magnetic short circuit, which is why the valve tappet does not generate the magnetic flux in order to avoid a magnetic short circuit Conductive material is to be produced, which usually leads to the use of materials that do not have a high and therefore permanent wear resistance.
Ist überdies der Magnetanker mit dem Ventilstößel einteilig und damit zwangsläufig aus dem gleichen magnetischen Werkstoff hergestellt, ergibt sich außer dem erwähnten magnetischen Kurzschluss die Gefahr eines Klemmens der Magnetanker-Ventilstößel-Baugruppe im Ventilgehäuse, sofern nicht auf möglichst kleine und damit aufwendige Fertigungstoleranzen geachtet wird.If, moreover, the magnet armature is integral with the valve tappet and therefore inevitably made of the same magnetic material, there is also the risk of the magnet armature / valve tappet assembly jamming in the valve housing in addition to the aforementioned magnetic short circuit, unless attention is paid to the smallest possible and therefore complex manufacturing tolerances.
Daher ist es die Aufgabe der vorliegenden Erfindung, ein Elektromagnetventil der angegebenen Art derart zu verbessern, dass die vorgenannten Nachteile nicht auftreten.It is therefore the object of the present invention to improve an electromagnetic valve of the specified type in such a way that the aforementioned disadvantages do not occur.
Diese Aufgabe wird erfindungsgemäß für ein Elektromagnetventil der angegebenen Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.According to the invention, this object is achieved for an electromagnetic valve of the specified type with the characterizing features of
Weitere Merkmale und Vorteile der Erfindung gehen im Folgenden aus der Beschreibung mehrerer Ausführungsbeispiele hervor.Further features and advantages of the invention emerge below from the description of several exemplary embodiments.
