Abstract
Description
Die Erfindung bezieht sich auf ein Ventil gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a Valve according to the generic term of claim 1.
Ein solches Ventil findet in der Mikrosystemtechnik eine Anwendung, wo es zum Öffnen und Schließen von Mikrokanälen genutzt wird, durch die Gase oder Flüssigkeiten geleitet werden.Such a valve takes place in the Microsystem technology an application where it is used to open and close microchannels is used through which gases or liquids are passed.
Solche Mikrokanäle sind beispielsweise innerhalb von Trägerelementen ausgebildet, die zur Aufnahme von Analysegeräten, Messeinrichtungen, Sensoren und Vorratsbehältern genutzt werden. Da diese Bauelemente sehr kleine Abmessungen aufweisen, sind sie oftmals schwer zu handhaben. Aus diesem Grund werden sie in solche Trägerelemente integriert. Die Kanäle eines solchen Trägerelements können ein ganzes Kanalsystem bilden. Innerhalb eines solchen Kanalsystems kann ein strömendes Medium beispielsweise auf mehre Kanäle umgelenkt werden, ein Kanal kann für den Durchlass eines strömenden Medium geöffnet und ein anderer Kanal geschlossen oder mehrere strömende Medien können gemeinsam in einen Kanal eingeleitet werden. Die bis jetzt in einem solchen Kanalsystem verwendeten Ventile ermöglichen das Öffnen, Schließen und Verbinden von Kanälen oftmals nicht so zuverlässig, wie das für die Analysen und Messungen und erforderlich ist, die mit den Bauelementen der Mikrotechnik durchgeführt werden.Such microchannels are, for example, within of carrier elements trained to accommodate analyzers, measuring devices, sensors and storage containers be used. Since these components have very small dimensions, they are often difficult to handle. Because of this, they will integrated in such support elements. The canals of such a support member can form entire channel system. Within such a channel system can be a pouring Medium can be diverted to multiple channels, for example, one channel can for the passage of a flowing Medium opened and another channel closed or several flowing media can together be introduced into a channel. So far in one Valve system used allow opening, closing and Connect channels often not so reliable, like that for the analyzes and measurements and is necessary with the components of microtechnology become.
Der Erfindung liegt die Aufgabe zugrunde, ein Ventil aufzuzeigen, das sehr fest schließt, dessen Ansprechzeiten an die Reaktionszeiten der Mikrotechnik angepasst sind, und das auf einfache Weise in das Kanalsystem vom Bauelementen der Mikrotechnik integriert werden kann.The invention is based on the object Show valve that closes very tightly, its response times the response times are adapted to the microtechnology, and that on simple way in the channel system from components of microtechnology can be integrated.
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.
