Abstract
Description
Die Erfindung bezieht sich auf eine Ventilanordnung mit wenigstens einem Ventil gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a Valve arrangement with at least one valve according to the preamble of the claim 1.
Eine solche Ventilanordnung finden in der Mikrosystemtechnik eine Anwendung, wo sie zum Öffnen und Schließen von Kanälen in Mikrosystemen genutzt wird, durch die Gase oder Flüssigkeiten geleitet werden. Das Öffnen oder Schließen von Kanälen übernehmen dabei die einzelnen Ventile.Find such a valve assembly in microsystem technology an application where it can be opened and Conclude of channels is used in microsystems, through which gases or liquids be directed. The opening or closing take over from channels the individual valves.
Es ist bereits ein Mikroventil bekannt, bei dem das Schließen des Ventils mittels Strömung und Differenzdruck erfolgt, wodurch eine Kugel auf den kreisförmigen Ventilsitz gedrückt und mit Hilfe eines Elektromagneten gehalten wird. Sind die beiden Bedingungen Strömung und/oder Differenzdruck nicht gegeben, so stellt sich ein nicht definierter Zustand der Kugel ein. Ein sicheres Schließen des Ventils wird dann nicht mehr gewährleistet. Der Elektromagnet, der die Kugel auf dem Ventilsitz hält, muss dabei ständig an einer elektrischen Spannungsquelle angeschlossen sein, so dass hierdurch viel Energie verbraucht wird. Sind in ein solches Mikrosystem eine Vielzahl von Ventilen integriert, so ist eine entsprechende Anzahl von Elektromagneten erforderlich, für die viel Platz benötigt wird, wodurch die Einrichtung unnötig vergrößert wird.A microvalve is already known where the closing of the valve by means of flow and differential pressure takes place, creating a ball on the circular valve seat depressed and is held with the help of an electromagnet. Are the two Current conditions and / or differential pressure is not given, it does not occur defined state of the ball. A safe closing of the The valve is then no longer guaranteed. The electromagnet that holds the ball on the valve seat must doing it all the time be connected to an electrical voltage source so that this consumes a lot of energy. Are in such a microsystem integrated a large number of valves, so is a corresponding one Number of electromagnets required for which a lot of space is required making the setup unnecessary is enlarged.
Der Erfindung liegt die Aufgabe zugrunde, eine Ventilanordnung aufzuzeigen, die geringere bauliche Abmessungen aufweist, kostengünstig hergestellt und Energie sparend betrieben werden kann.The invention has for its object a Valve arrangement to show the smaller structural dimensions has, inexpensive can be manufactured and operated in an energy-saving manner.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This task is due to the characteristics of claim 1 solved.
Weitere erfinderische Merkmale sind in den abhängigen Ansprüchen gekennzeichnet.Other inventive features are in the dependent claims characterized.
Die Erfindung wird nachfolgend an Hand von schematischen Zeichnungen näher erläutert.The invention will follow Hand explained in more detail by schematic drawings.
