Abstract
Anordnung (1) zur Bevorratung eines gefrierfähigen Fluids (15), insbesondere eines Reduktionsmittels zur Nachbehandlung von Abgasen einer Brennkraftmaschine, mit einem Vorratsbehälter (3) für das Fluid, dadurch gekennzeichnet, daß eine Venturi-Anordnung (20, 200, 210) innerhalb des Vorratsbehälters (3) vorgesehen ist, so daß durch Beaufschlagung der Venturi-Anordnung (20, 200, 210) mit dem Fluid (15) Fluid aus dem Vorratsbehälter über mindestens eine Venturi-Ansaugöffnung (34, 340, 341) angesaugt und innerhalb des Vorratsbehälters umgewälzt (24) werden kann.Arrangement (1) for storing a freezable fluid (15), in particular a reducing agent for after-treatment of exhaust gases of an internal combustion engine, with a reservoir (3) for the fluid, characterized in that a Venturi arrangement (20, 200, 210) within the Reservoir (3) is provided, so that sucked by applying the Venturi arrangement (20, 200, 210) with the fluid (15) fluid from the reservoir via at least one Venturi suction port (34, 340, 341) and within the reservoir can be circulated (24).
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Anordnung zur Bevorratung eines gefrierfähigen Fluids nach der Gattung des unabhängigen Anspruchs.The invention is based on an arrangement for storing a freezable fluid according to the preamble of the independent claim.

Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße Anordnung zur Bevorratung eines gefrierfähigen Fluids mit den kennzeichnenden Merkmalen des unabhängigen Anspruchs hat demgegenüber den Vorteil einer verbesserten Durchmischung des Fluids. Als weiterer besonderer Vorteil ist anzusehen, daß eine verbesserte Wärmeverteilung erreicht wird. Dies ist insbesondere dann von Vorteil, wenn bei Inbetriebnahme der Tankanordnung das Fluid jedenfalls teilweise eingefroren ist und erst durch eine Heizanordnung verflüssigt werden muß. Die von der Heizanordnung bereitgestellte Wärme kann durch die erfindungsgemäße Anordnung durch Umwälzen einer bereits vorhandenen flüssigen Phase des Fluids besser im Tank verteilt werden, um schnell ein großvolumiges Auftauen des Fluids zu gewährleisten, ohne großflächige bzw. großvolumige Heizelemente vorsehen zu müssen, die einerseits kostenaufwendig sind und andererseits unter Umständen an individuelle Tankformen angepaßt werden müssen.The inventive arrangement for storing a freezable fluid with the characterizing features of the independent claim has the advantage of improved mixing of the fluid. Another particular advantage is to be considered that an improved heat distribution is achieved. This is particularly advantageous when the fluid is at least partially frozen during commissioning of the tank assembly and must first be liquefied by a heating arrangement. The heat provided by the heating arrangement can be better distributed by the inventive arrangement by circulating an existing liquid phase of the fluid in the tank to quickly ensure a large-scale thawing of the fluid without having to provide large-scale or large-volume heating elements, which are expensive on the one hand and on the other hand may need to be adapted to individual tank shapes.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im unabhängigen Anspruch angegebenen Anordnung zur Bevorratung möglich.The measures listed in the dependent claims advantageous refinements and improvements of the independent claim arrangement for storage are possible.

Beschreibung der AusführungsbeispieleDescription of the embodiments
Bei der beschriebenen hydraulischen Konfiguration kann die Pumpe kontinuierlich betrieben werden, auch wenn das Dosiermodul die Auslaßleitung verschlossen läßt. Vom Dosiermodul nicht benötigte Fluidmengen werden in den Tank zurückgefördert. Der erforderliche Einspritzdruck am Dosiermodul in den Abgastrakt hinein wird durch Aufstauung des Rücklaufs mit Hilfe des Drosselelements
Alternativ kann sich, ohne Änderung des hydraulischen Prinzips, ein Fluid-Versorgungsmodul bzw. Fördermodul, welches die Pumpe und die Rücklaufleitung samt Drosselement in einem integrierten Aufbau enthalten kann, auch innerhalb des Vorratsbehälters befinden, d.h. vollständig unterhalb des Fluidspiegels angeordnet sein. Dabei kann das Versorgungsmodul in einem Bodenbereich
Eine nicht näher dargestellte Heizung, die auch in dem genannten Fluid-Versorgungsmodul integriert sein kann, dient zur Verflüssigung gefrorenen Fluids.A heater, not shown, which may also be integrated in said fluid supply module, serves for the liquefaction of frozen fluid.
Idealerweise ist der Druckverlust der Düse
