Description
Die Erfindung betrifft eine Filtervorrichtung mit einer Filtereinheit und einer Pumpeneinheit, die das zu filtrierende Fluid über die Filtereinheit führt und die in Einbaulage unterhalb der Filtereinheit an dieser angeordnet ist, wobei die Filtereinheit ein Filterelement mit einem in einem Filtergehäuse angeordneten Filtermaterial aufweist, das für eine Durchströmung des zu filtrierenden Fluids von außen nach innen sich an einem Stützteil abstützt, dessen Inneres fluidführend an die Pumpeneinheit angeschlossen ist und das außenumfangsseitig von einem hülsenartigen Umfassungsmantel umgeben i st.The invention relates to a filter device a filter unit and a pump unit that the to be filtered Fluid over the filter unit leads and arranged in the installed position below the filter unit is, wherein the filter unit is a filter element with a in one filter housing arranged filter material, which for a flow of fluids to be filtered from the outside inward on a support member supported, its interior is fluid is connected to the pump unit and the outside circumference from a sleeve-like Surrounding jacket surround i st.
Dahingehende Filtervorrichtungen
werden von der Anmelderin unter der technischen Bezeichnung "OffLine Filter" und unter der Markenbezeichnung "OLF-Compact Hydraulic
Line" gemäß ihrem Prospekt
Nr. DEF
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Filtervorrichtung der eingangs genannten Art dahingehend weiter zu verbessern, daß mit wenigen Bauteilen in kostengünstiger Weise eine selbständige Entlüftung erreicht ist und daß es nicht ungewollt zu schädigenden Luftpolstern innerhalb der Filtervorrichtung kommen kann. Eine dahingehende Aufgabe löst eine Filtervorrichtung mit den Merkmalen des Patentanspruches 1 in seiner Gesamtheit.Based on this state of the art the invention has for its object a filter device of the beginning mentioned type to further improve that with a few Components in less expensive Way an independent vent is achieved and that it not accidentally damaged Air cushions can come inside the filter device. A pertinent one Solves task a filter device with the features of claim 1 In its entirety.
Dadurch, daß gemäß dem kennzeichnenden Teil des Patentanspruches 1, daß am oberen, der Pumpeneinheit gegenüberliegenden Ende der Filtereinheit der Umfassungsmantel mit einem vorgebbaren Abstand früher endet oder derart mit großflächigen Durchlaßstellen versehen ist, daß zumindest das während der Filtration auftretende Luftvolumen aus dem Filterelement verdrängt ist, kann das derart die Pumpeneinheit schädigende Luftpolster nicht mehr in diese gelangen und den schädlichen "Rückwärts"-Lauf der Saug- oder Förderpumpe verursachen. Der Umfassungsmantel in der Art einer Hülse übernimmt über den genannten Abstand bzw. die großflächigen Durchlaßstellen die Funktion des ansonsten separat innerhalb der Vorrichtung vorhandenen Steigrohres, wobei die erfindungsgemäße Lösung gegenüber dem Einbau eines zusätzlichen Steigrohres den Vorteil hat, daß man kein Herstellkosten verursachendes, zusätzliches Bauteil benötigt, das darüber hinaus Einbauraum benötigt und zu konstruktiv groß aufbauenden Filtervorrichtungen führt. Des weiteren kann der Umfassungsmantel dazu dienen, das empfindliche Filtermaterial vor Beschädigungen, insbesondere bei der Handhabung außerhalb der Filtervorrichtung, zu schützen.In that, according to the characteristic part of claim 1 that on upper, opposite the pump unit End of the filter unit, the surrounding jacket with a predeterminable Distance earlier ends or so with large passages is provided that at least that during the Air volume occurring in the filter element is displaced, can no longer damage the air cushion damaging the pump unit get into it and the harmful "backward" run of the suction or feed pump cause. The surrounding jacket in the manner of a sleeve takes over the mentioned distance or the large-area passage points the function of what is otherwise separate within the device Riser pipe, the solution according to the invention compared to the installation of an additional riser pipe has the advantage that no additional component which causes production costs, which about that Installation space is also required and too constructively large Filter devices leads. Furthermore, the surrounding jacket can serve to protect the sensitive Filter material from damage, especially when handling outside the filter device, to protect.
Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Filtervorrichtung ist der Umfassungsmantel an sich mit einer Perforation für den Durchlaß des zu filtrierenden Fluids versehen, wobei die großflächigen Durchlaßstellen aus Durchlaßkreisen gebildet sind, deren einzelner Durchmesser mehrfach größer gewählt ist als eine einzelne Perforationsstelle des Umfassungsmantels. Der dahingehende Umfassungsmantel läßt sich insbesondere aus einem Streckmetallmantel günstig erhalten, der in verkürzter Baulänge den gewünschten Durchlaß für das Luftpolster bildet oder in den Durchlaßstellen mit vergrößerter Durchlaßquerschnittsstelle einbringbar ist.In a preferred embodiment the filter device according to the invention is the surrounding jacket itself with a perforation for the passage of the provided filtering fluids, the large-area passage points from pass circles are formed, the individual diameter of which is selected to be several times larger as a single perforation point of the surrounding jacket. The this enclosing jacket can be Inexpensive, especially from an expanded metal jacket, which has a shorter overall length desired Passage for the air cushion forms or in the passage points with enlarged passage cross-section can be introduced.
Neben der gezeigten Möglichkeit der Ausbildung für den Umfassungsmantel ist alternativ bei einer anderen Ausführungsform vorgesehen, den Umfassungsmantel bis auf die Stellen des Durchlasses an seinem einen Ende undurchlässig zu gestalten, so daß der Fluiddurchtritt für das zu filtrierende Fluid und das Verdrängen der Umgebungsluft an einer Seite des Filterelementes stattfinden.In addition to the option shown training for the surrounding jacket is alternatively in another embodiment provided, the surrounding jacket to the places of the passage impermeable at one end to shape so that the Fluid passage for the fluid to be filtered and the displacement of the ambient air in one Side of the filter element.
Bei einer weiteren bevorzugten Ausführungsform der erfindungsgemäßen Filtervorrichtung verlaufen die kreisförmigen Durchlaßstellen in zwei übereinander angeordneten Reihen im Bereich des einen freien Endes des Filterelementes innerhalb des Umfassungsmantels, wobei die Durchlaßstellen der einen Reihe um zumindest einen Teil der jeweiligen Durchlaßstelle der anderen Reihe radial zu dieser versetzt angeordnet ist. Auf diese Art und Weise kann bevorzugt über die untere Reihe an Durchlaßstellen der Fluideintritt erfolgen, sofern der Umgebungsmantel ansonsten undurchlässig gestaltet sein sollte und über die zuoberst liegende Reihe kann der Entlüftungsvorgang auch unter Bildung eines Luftpolsters in diesem Bereich vonstatten gehen.In a further preferred embodiment of the filter device according to the invention, the circular passage points run in two rows arranged one above the other in the area of the a free end of the filter element within the surrounding jacket, the passage points of the one row being offset radially to at least part of the respective passage point of the other row. In this way, the fluid entry can preferably take place via the lower row at passage points, provided the surrounding jacket should otherwise be made impermeable, and the venting process can also take place via the row located at the top, with the formation of an air cushion in this area.
Bei einer weiteren bevorzugten Ausführungsform der erfindungsgemäßen Filtervorrichtung ist das Filterelement als Austauschbauteil ausgebildet und weist an seinen beiden Enden jeweils eine Endkappe auf, die über ein Klebstoffbett mit den jeweils zugeordneten Enden von Stützrohr, Filtermaterial und Umfangsmantel fest verbunden ist. Hierdurch ergibt sich eine kompakt aufbauende Gesamtfiltereinheit mit einer guten Austauschmöglichkeit für ein verbrauchtes Filterelement gegen ein Neu-Filterelement.In a further preferred embodiment the filter device according to the invention the filter element is designed as an exchange component and instructs its two ends each have an end cap that over a Adhesive bed with the respectively assigned ends of the support tube, Filter material and peripheral jacket is firmly connected. This gives a compact overall filter unit with a good one exchange possibility for a used one Filter element against a new filter element.
Weitere vorteilhafte Ausführungsformen sind Gegenstand der sonstigen Unteransprüche.Further advantageous embodiments are the subject of other subclaims.
