Abstract
Description
Die Erfindung betrifft ein Ventil mit einem Ventilgehäuse, in dem ein Ventilglied axial bewegbar angeordnet ist, mit wenigstens zwei Permanentmagnetanordnungen zum Halten des Ventilglieds durch Magnetkraft wenigstens in zwei entgegengesetzten, als Anschlagstellungen ausgebildeten Haltestellungen und mit Mitteln zum Bewegen des Ventilglieds gegen die magnetische Haltekraft aus den Haltestellungen heraus.The invention relates to a valve with a valve housing in which a valve member is arranged axially movable, with at least two permanent magnet arrangements for holding the valve member by magnetic force at least in two opposite, formed as stop positions holding positions and means for moving the valve member against the magnetic holding force from the Holds out.
Bei einem derartigen, aus der
Eine Aufgabe der vorliegenden Erfindung besteht darin, ein Ventil der eingangs genannten Gattung so zu verbessern, dass das Ventilglied auch bei eventuellen Erschütterungen an der jeweiligen Anschlagstellung gehalten wird.An object of the present invention is to improve a valve of the type mentioned so that the valve member is held even in case of possible shocks to the respective stop position.
Diese Aufgabe wird erfindungsgemäß durch ein Ventil mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a valve with the features of claim 1.
Durch die erfindungsgemäße Ausgestaltung und Positionierung der Permanentmagnetanordnungen wird in vorteilhafter Weise erreicht, dass sich bei einem eventuellen Wegbewegen des Ventilglieds aus einer Haltestellung, insbesondere aus einer der beiden Anschlagstellungen, beispielsweise durch Erschütterungen oder durch einen Schlag, die magnetische Rückstellkraft bei zunehmender Entfernung von der jeweiligen Haltestellung erhöht, so dass eine sichere und automatische Rückführung zur jeweiligen Haltestellung gewährleistet ist und keine Gefahr besteht, dass das Ventilglied unkontrolliert in eine andere Haltestellung gelangt. Ein weiterer Vorteil besteht darin, dass sich die gehäusefeste Permanentmagnetanordnung nicht im Bereich der Anschlagstellungen befindet, so dass sie nicht gegen den Auftreffimpuls des Ventilglieds geschützt werden muss bzw. dass entsprechende Beschädigungen verhindert werden.The inventive design and positioning of the permanent magnet arrangements is achieved in an advantageous manner that in a possible moving away of the valve member from a holding position, in particular from one of the two stop positions, for example, by vibration or shock, the magnetic restoring force with increasing distance from the respective Increased holding position, so that a safe and automatic return to the respective holding position is guaranteed and there is no risk that the valve member enters uncontrolled in another holding position. Another advantage is that the housing-fixed permanent magnet arrangement is not in the region of the stop positions, so that it does not have to be protected against the impingement pulse of the valve member and that corresponding damage can be prevented.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen Ventils möglich.The measures listed in the dependent claims advantageous refinements and improvements of the claim 1 valve are possible.
Zur Bildung wenigstens einer weiteren zwischen den beiden Anschlagstellungen liegenden Haltestellung besteht die erste oder zweite Permanentmagnetanordnung in vorteilhafter Weise aus zwei in axialer Richtung voneinander beabstandeten gleichsinnig axial polarisierten Teilmagnetanordnungen, wobei die jeweils andere Permanentmagnetanordnung in dieser weiteren Haltestellung eine axiale Mittelstellung zwischen diesen beiden Teilmagnetanordnungen einnimmt. Auf diese Weise lassen sich bei geringem Aufwand beliebige weitere Haltestellungen erzeugen.In order to form at least one further holding position lying between the two stop positions, the first or second permanent magnet arrangement consists advantageously of two axially spaced, axially polarized partial magnet arrangements spaced apart in the axial direction, the other permanent magnet arrangement assuming an axial center position between these two partial magnet arrangements in this further holding position. In this way, any other stops can be generated with little effort.
Die Erfindung eignet sich besonders bei einer Ausbildung des Ventils als vorgesteuertes Impulsventil.The invention is particularly suitable for a design of the valve as a pilot operated pulse valve.
In einer bevorzugten Ausführung weisen die erste Permanentmagnetanordnung oder deren Teilmagnetanordnungen wenigstens einen die Bewegungsbahn des Ventilglieds umgreifenden Ringmagneten auf, der einstückig ausgebildet ist oder aus mehreren aneinander stoßenden oder beabstandeten Teilmagneten besteht. Hierdurch kann das Ventilglied beliebige Winkellagen einnehmen.In a preferred embodiment, the first permanent magnet arrangement or its partial magnet arrangements have at least one ring magnet encompassing the path of movement of the valve member, which is formed in one piece or consists of a plurality of abutting or spaced partial magnets. As a result, the valve member can assume any angular positions.
Die zweite im Ventilglied enthaltene Permanentmagnetanordnung weist bevorzugt wenigstens einen Ring- oder Scheibenmagneten auf, wobei auch hier der Ringmagnet einstückig ausgebildet ist oder aus mehreren aneinander stoßenden oder beabstandeten Teilmagneten besteht. Dabei können auch mehrere Ring- oder Scheibenmagnete in axialer Richtung nebeneinander oder durch Magnetleitstücke voneinander beabstandet angeordnet sein, um beispielsweise die Magnetkraft zu erhöhen, ohne zu großvolumige Magnete einsetzen zu müssen.The second permanent magnet arrangement contained in the valve member preferably has at least one annular or disc magnet, whereby here too the annular magnet is formed in one piece or consists of a plurality of abutting or spaced partial magnets. In this case, a plurality of ring or disc magnets in the axial direction next to each other or by Magnetleitstücke spaced from each other to be, for example, to increase the magnetic force without having to use bulky magnets.
In einer bevorzugten Ausgestaltung der Erfindung ist das Ventil als Schieberventil und das Ventilglied als Ventilschieber ausgebildet, wobei die Mittel zum Bewegen des Ventilglieds als fluidische oder elektromechanische Impulsantriebe ausgebildet sind. Kurze Impulse genügen dabei, um das Ventilglied jeweils aus seiner aktuellen Haltestellung heraus zur nächsten Haltestellung zu bewegen. Durch das Ventilglied in den Haltestellungen werden Ventilöffnungen verschlossen und/oder geöffnet.In a preferred embodiment of the invention, the valve is designed as a slide valve and the valve member as a valve slide, wherein the means for moving the valve member are formed as fluidic or electromechanical pulse drives. Short impulses suffice to move the valve member from its current holding position to the next holding position. Valve openings are closed and / or opened by the valve member in the holding positions.
Das Ventil ist zweckmäßigerweise als Mehrstellungsventil ausgebildet, beispielsweise als Zweistellungs- oder Dreistellungsventil. Ausführungen als 3/2- oder 5/2- oder 5/3-Wegeventile sind dabei besonders bevorzugt.The valve is expediently designed as a multi-position valve, for example as a two-position or three-position valve. Versions as 3 / 2- or 5 / 2- or 5/3-way valves are particularly preferred.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen:Embodiments of the invention are illustrated in the drawings and explained in more detail in the following description. Show it:
