Eine zielgerichtete Steuerung der Teilmassenströme durch das innere und äußere Filterelement ist nicht vorgesehen, was die Gefahr birgt, dass die Filterelemente auf Grund ihrer unterschiedlich großen Anströmflächen sich nicht gleichmäßig mit Schmutzpartikeln zusetzen. Vielmehr wird auf Grund der kleineren Anströmseite das innere Filterelement sich zuerst zusetzen, so dass der gesamte Massenstrom durch das außen liegende Filterelement strömen muss und auch dieses Filterelement durch die erhöhte Schmutzbelastung in kurzer Zeit an Filtrationsleistung einbüßt.A Targeted control of the partial mass flows through the inner and outer filter element is not provided, which carries the risk that the filter elements due to their different sizes Flow surfaces are not uniform Add with dirt particles. Rather, due to the smaller The inflow side, the inner filter element first, so that the entire mass flow through the outside Filter element must flow and also this filter element due to the increased dirt load in a short time to filtration performance loses.

Offenbarung der ErfindungDisclosure of the invention
Der Erfindung liegt die Aufgabe zu Grunde, einen Flüssigkeitsfilter zu schaffen, bei dem in effektiver Weise dispersiv enthaltene Wassertröpfchen in einem Fluid abgeschieden werden können.Of the Invention is based on the object, a liquid filter to effectively disperse contained water droplets can be deposited in a fluid.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.These Task is according to the invention with the features of claim 1 solved. The subclaims give appropriate training.
Der erfindungsgemäße Flüssigkeitsfilter weist in einem Filtergehäuse ein Coalescer-Element sowie ein strömungstechnisch nachgeschaltetes Hauptfilterelement auf, wobei das Coalescer-Element zum Zusammenführen bzw. Anlagern größerer Wassertröpfchen des dispersiv in der zu reinigenden Flüssigkeit enthaltenen Wassers dient. Coalescer-Element und Hauptfilterelement sind jeweils ringförmig ausgebildet und konzentrisch ineinander gesetzt, dergestalt, dass das außen liegende Element das radial innen liegende Element umschließt. Zwischen den beiden Elementen ist ein Ringspalt gebildet, außerdem weisen beide Elemente die gleiche radiale Durchströmungsrichtung auf.Of the has inventive liquid filter in a filter housing, a coalescer element and a fluidically downstream main filter element on, wherein the coalescing element for merging or Investing larger water droplets of the dispersively contained in the liquid to be purified Water serves. Coalescer element and main filter element are respectively annular and concentric with each other, such that the outer element is the radial one inside element encloses. Between the two Elements is an annular gap formed, also have both Elements on the same radial flow direction.
Diese Ausbildung des Flüssigkeitsfilters, bei dem es sich vorzugsweise um einen Kraftstofffilter für Brennkraftmaschinen, beispielsweise um einen Dieselkraftstofffilter handelt, weist den Vorteil einer einheitlichen Durchströmungsrichtung für Coalescer-Element und Hauptfilterelement auf, so dass es im Unterschied zum Stand der Technik nicht erforderlich ist, die Strömungsrichtung nach dem Durchlaufen des Coalescer-Elementes zu ändern, wodurch Strömungsverluste bzw. Druckverluste vermieden werden. Ein weiterer Vorteil liegt darin, dass der Ringspalt zum Ableiten der größeren, im Coalescer-Element angelagerten Wassertröpfchen dient. Bereits im Coalescer-Element werden größere Wassertröpfchen erzeugt, die spätestens an der Reinseite des Hauptfilterelementes abgeschieden werden und in Richtung des Bodens des Ringspaltes strömen, von wo aus das gesammelte Wasser abgeleitet werden kann. Dies hat zur Folge, dass der das Hauptfilterelement passierende Fluidstrom einen erheblich geringeren Wasseranteil aufweist bzw. ggf. sogar vollständig frei von Wasser ist, wodurch der Reinheitsgrad des Fluids erhöht und beispielsweise im Falle eines Kraftstofffilters die Verbrennung in der Brennkraftmaschine verbessert wird. Außerdem können Schmutzpartikel aus dem Fluid im Hauptfilterelement besser ausfiltriert werden, so dass auch der Wirkungsgrad im Hauptfilterelement verbessert wird.This design of the liquid filter, which is preferably a fuel filter for internal combustion engines, for example a diesel fuel filter, has the advantage of a uniform flow direction for coalescing element and main filter element, so that it is not required in contrast to the prior art, the Change flow direction after passing through the coalescing element, whereby flow losses or pressure losses are avoided. Another advantage is that the annular gap serves to drain off the larger water droplets deposited in the coalescing element. Already in the coalescing element larger water droplets are generated, which are deposited at the latest on the clean side of the main filter element and flow in the direction of the bottom of the annular gap, from where the collected water can be derived. As a result, the fluid flow passing through the main filter element has a considerably lower water content or may even be completely free of water, whereby the degree of purity of the fluid is increased and, for example, in the case of a fuel filter, the combustion in the internal combustion engine is improved. In addition, dirt particles from the fluid in Hauptfilterele be filtered out better, so that the efficiency in the main filter element is improved.
Gemäß einer vorteilhaften Weiterbildung ist vorgesehen, dass das Coalescer-Element radial außen liegt und das Hauptfilterelement radial innen, so dass das Hauptfilterelement ringförmig von dem Coalescer-Element eingeschlossen ist. In diesem Fall ist die Durchströmungsrichtung radial von außen nach innen. Diese Ausführung hat den Vorteil, dass die radial außen liegende Seite des Hauptfilterelementes die Rohseite bildet und im Filtermaterial in Radialrichtung von außen nach innen gesehen größere Schmutzpartikel, welche in der zu reinigenden Flüssigkeit enthalten sind, vorzugsweise im radial weiter außen liegenden Bereich aus filtriert werden. Mit zunehmender Annäherung an die die Reinseite bildende radiale Innenseite des Hauptfilterelementes nimmt die Schmutzbelastung im Fluidstrom insgesamt ab und können feinere Schmutzpartikel im Filtermaterial ausfiltriert werden.According to one advantageous development is provided that the coalescer element radially outward and the main filter element radially inward, such that the main filter element is annular from the coalescing element is included. In this case, the flow direction radially from outside to inside. This execution has the advantage that the radially outer side of the Main filter element forms the raw side and in the filter material in the radial direction larger from outside to inside Dirt particles, which in the liquid to be cleaned are included, preferably in the radially outer Be filtered out of range. With increasing approach to which the clean side forming radial inside of the main filter element takes the dirt load in the fluid flow from and can finer dirt particles are filtered out in the filter material.
Im Coalescer-Element wird radial von außen nach innen eine zunehmende Anlagerung der Wassertröpfchen erzielt, so dass die größten Wassertröpfchen an der radialen Innenseite des Coalescer-Elementes zu finden sind, die zugleich den Ringspalt begrenzt. Somit werden die größten Wassertröpfchen automatisch im Ringspalt abgesondert und können über diesen abgeleitet werden.in the Coalescer element becomes radially from outside to inside one increased accumulation of water droplets, so that the largest water droplets at the radial Inside the coalescer element are found at the same time limited to the annular gap. Thus, the largest Water droplets automatically separated in the annular gap and can be derived from this.
Im Ringspalt befindet sich zweckmäßigerweise zumindest eine Ablassöffnung, vorzugsweise im Boden des Ringspaltes, zum Ableiten des abgeschiedenen Wassers. Die Ablassöffnung ist vorteilhafterweise in eine stirnseitige Endscheibe eingebracht, die bevorzugt sowohl die Stirnseite des Coalescer-Elementes als auch die Stirnseite des Hauptfilterelementes abdeckt. Hierbei kann es zweckmäßig sein, einteilig mit der bevorzugt aus Kunststoff gefertigten Endscheibe Ablassstutzen auszubilden, die mit der Ablassöffnung in den Ringspalt münden und die zweckmäßigerweise auf der dem Ringspalt abgewandten Seite in eine zugeordnete Gegenkontur im Gehäuse des Flüssigkeitsfilters eingreifen.in the Annular gap is expediently at least a discharge opening, preferably in the bottom of the annular gap, for draining the separated water. The drain opening is advantageously introduced into a front-side end plate, which prefers both the end face of the coalescer element as also covers the front side of the main filter element. Here can it be expedient, in one piece with the preferred Made of plastic end plate drain plug, which open into the annular gap with the discharge opening and the expediently on the annular gap opposite side in an associated counter-contour in the housing engage the liquid filter.
Die Ablassöffnung – und dementsprechend auch der Ablassstutzen – kann entweder als begrenzte Öffnung, beispielsweise als kreisrunde Öffnung ausgebildet sein oder als Öffnung mit begrenztem Querschnitt mit einer anderweitigen Querschnittsgeometrie, beispielsweise eine rechteckige Öffnung. Möglich ist aber auch gemäß einer alternativen Ausführung eine ringförmig ausgebildete Ablassöffnung, die sich entweder über den gesamten Umfang des Ringspaltes oder über ein begrenztes Winkelsegment erstreckt. Im Falle einzelner Ablassöffnungen können mehrere derartiger Ablassöffnungen über den Umfang verteilt vorgesehen sein. Auch im Falle von ringförmigen, sich über ein begrenztes Winkelsegment erstreckenden Ablassöffnungen können ggf. mehrere derartiger Ablassöffnungen eingebracht sein. Der bzw. die Ablassstutzen sind an die Querschnittsgeometrie der Ablassöffnung angepasst.The Discharge opening - and accordingly also the drain port - can either formed as a limited opening, for example as a circular opening or as an opening with a limited cross-section with a otherwise cross-sectional geometry, such as a rectangular opening. But it is also possible according to an alternative Execution of an annular discharge opening, extending either over the entire circumference of the annular gap or extends over a limited angle segment. In the event of individual discharge openings can several such Provided drain openings distributed over the circumference be. Also in the case of annular, over a limited angular segment extending vent openings If necessary, several such discharge openings be introduced. The drainage nozzle (s) are to the cross-sectional geometry adapted to the drain opening.
