Abstract
Einem Flüssigkeitsfilter mit einem Filtergehäuse und einem darin aufgenommenen Filtersack ist über einen Einlassstutzen zu reinigende Flüssigkeit zuführbar, wobei in den Filtersack ein Stützgerüst eingebracht ist. In den Einlassstutzen ist eine Einlasshülse eingesetzt, die Bestandteil des Stützgerüsts ist.A liquid filter with a filter housing and a filter bag accommodated therein can be supplied with liquid to be cleaned via an inlet connection, a support frame being introduced into the filter bag. An inlet sleeve, which is part of the support frame, is inserted into the inlet connector.
Description
Die Erfindung bezieht sich auf einen Flüssigkeitsfilter, insbesondere für Getriebeöl in Kraftfahrzeugen, nach dem Oberbegriff des Anspruches 1.The invention relates to a Liquid filters, especially for transmission oil in motor vehicles, according to the preamble of claim 1.
Ein derartiger Flüssigkeitsfilter ist aus der Druckschrift
Von diesem Stand der Technik ausgehend liegt der Erfindung das Problem zugrunde, einen gattungsgemäßen Flüssigkeitsfilter konstruktiv einfach auszubilden. Es soll insbesondere unter allen Betriebsbedingungen eine genau definierte Position des Filterelementes im Flüssigkeitsfilter gewährleistet sein.Based on this state of the art the invention addresses the problem of a generic liquid filter easy to design. It is meant to be among all Operating conditions a precisely defined position of the filter element in the liquid filter to be guaranteed.
Dieses Problem wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This problem is solved according to the invention with the Features of claim 1 solved. The subclaims give appropriate training on.
Bei dem erfindungsgemäßen Flüssigkeitsfilter
ist in den Einlassstutzen eine Einlasshülse eingesetzt, die einen Bestandteil
des Stützgerüstes im
Filtersack bildet und die Filterwandungen des Filtersackes auf Abstand
zueinander hält.
Der Einlasshülse kommt
somit eine Mehrfachfunktion zu:
Die Einlasshülse sorgt
zum einen für
eine feste Verbindung zwischen Stützgerüst und Filtergehäuse, so dass
das Stützgerüst und auch
der Filtersack in einer definierten Position im Innenraum des Filtergehäuses gehalten
sind. Die Zu- und Abströmung
des zu reinigenden Mediums kann auf diese Weise besser gesteuert
werden.In the case of the liquid filter according to the invention, an inlet sleeve is inserted into the inlet nozzle, which forms part of the supporting structure in the filter bag and keeps the filter walls of the filter bag at a distance from one another. The inlet sleeve therefore has a multiple function:
On the one hand, the inlet sleeve ensures a firm connection between the support structure and the filter housing, so that the support structure and also the filter bag are held in a defined position in the interior of the filter housing. The inflow and outflow of the medium to be cleaned can be better controlled in this way.
Zum anderen wird eine vereinfachte Konstruktion erreicht, da die Einlasshülse zugleich ein Abstandselement des Stützgerüstes bildet. In einer besonders einfachen Ausführung ist die Einlasshülse identisch mit dem Stützgerüst.The other is a simplified one Construction achieved because the inlet sleeve is also a spacer of the scaffold. In a particularly simple version, the inlet sleeve is identical with the scaffolding.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass die Einlasshülse als Klemmhülse ausgebildet ist, welche einen die Hülse unmittelbar umrandenden Filtersackabschnitt an die Gehäusewandung festklemmt. Dieser Klemmbereich zwischen Hülse und Gehäusewandung dichtet die Filterrohseite – im Bereich der Zuströmung zum Filtergehäuse – von der Filterreinseite im Bereich der Abströmung aus dem Filtergehäuse ab. Zur Unterstützung und Verbesserung der Klemmwirkung kann auf der radialen Außenseite der zweckmäßig zylindrischen Einlasshülse ein umlaufender Kragen ausgebildet sein, der auf einem zugeordneten Flansch auf der Innenseite der Gehäusewandung aufliegt, wodurch eine ring förmige Klemmfläche gebildet wird, auf der ein Abschnitt des Filtersackes festgeklemmt werden kann.In an expedient further training, that the inlet sleeve as a clamping sleeve is formed which directly surrounds the sleeve Filter bag section on the housing wall clamps. This clamping area between the sleeve and the housing wall seals the filter raw side - in the area the influx to the filter housing - from the Clean filter side in the area of the outflow from the filter housing. For support and improve the clamping effect on the radial outside the appropriately cylindrical inlet sleeve a circumferential collar can be formed on an associated Flange rests on the inside of the housing wall, whereby a ring shaped clamping surface is formed, on which a portion of the filter bag is clamped can be.
Gemäß einer vorteilhaften Weiterbildung umfasst das Stützgerüst zusätzlich zu der Einlasshülse auch mindestens einen Abstandshalter, der mit der Einlasshülse über eine Verbindungsstrebe verbunden ist. Der zur Einlasshülse beabstandete Abstandshalter hält ebenfalls gegenüberliegende Filterwandseiten des Filtersackes auf Abstand, so dass das Stützgerüst insgesamt zumindest zwei Stellen aufweist, über die der Filtersack offen gehalten wird. In einer vorteilhaften Ausführung können eine Mehrzahl von Abstandshaltern vorgesehen sein, die sich insbesondere in gleichem radialen Abstand um die zentrale Einlasshülse gruppieren.According to an advantageous further development the scaffolding in addition to the inlet sleeve also at least one spacer, which with the inlet sleeve over a Connection strut is connected. The one spaced from the inlet sleeve Spacer holds also opposite Filter wall sides of the filter bag at a distance, so that the support structure as a whole has at least two points over which the filter bag is open is held. In an advantageous embodiment, a plurality of spacers can be provided, in particular at the same radial distance around the central inlet sleeve group.
Zumindest ein Abstandshalter kann ein Magnetelement aufweisen, wodurch metallischer Abrieb in der Flüssigkeit, der durch die Filterwände nicht ausgesondert wird, aus der Flüssigkeit entfernt werden kann. Zweckmäßig ist der magnetische Abstandshalter unmittelbar benachbart zur Abströmöffnung angeordnet, über die das gesamte, gereinigte Medium abströmen muss, so dass auch der gesamte Flüssigkeitsstrom noch einer zusätzlichen magnetischen Reinigung unterzogen wird.At least one spacer can have a magnetic element, whereby metallic abrasion in the Liquid, through the filter walls is not separated out, can be removed from the liquid. Is expedient the magnetic spacer is arranged immediately adjacent to the outflow opening, via the the entire, cleaned medium must flow out, so that the total fluid flow another one undergoes magnetic cleaning.
Der Filtersack besteht vorteilhaft aus einem Filtervlies, das zur Bildung der Tasche bzw. des Sackes zusammengelegt wird, wobei die zusammengelegten Enden des Vlieses vorteilhaft zwischen einer Gehäuseoberschale und einer Gehäuseunterschale des Filtergehäuses eingeklemmt werden. Auf diese Weise kann ein strömungsdicht abgeschlossener Filterinnenraum im Filtersack gebildet werden.The filter bag is advantageous from a filter fleece, which forms the bag or sack is folded, the folded ends of the fleece advantageous between an upper housing shell and a lower housing shell of the filter housing be pinched. In this way, a flow-tight can Filter interior are formed in the filter bag.
