Abstract

In order to achieve an enlargement of the filter surface area in exchangeable lubricant filters with virtually the same space requirement, the filter element is constructed with the filter pot surrounding it being no longer circular cylindrical but rectangular.

Description

Die Erfindung bezieht sich auf eine Vorrichtung der im Oberbegriff des ersten Anspruchs angegebenen Art.The invention relates to a device in Preamble of the first claim specified type.

Aus der DE-AS 20 11 041 ist ein derartiges Schmier­ stoffilter bekannt. Hierbei wird akkordeonartig gefal­ tetes Filtermaterial verwendet, welches über die gesamte Breite des Filtertopfes verläuft. Der Anfang und das Ende des Filtermaterials sind mit dem Filtertopf dicht verbunden. Dadurch entstehen seitlich neben dem Filter­ material Ein- und Auslaßkammern für das zu filternde Schmiermittel.Such a lubrication is known from DE-AS 20 11 041 known fabric filter. This is done accordion-like tetes filter material used, which over the entire The width of the filter bowl runs. The beginning and that The end of the filter material are tight with the filter bowl connected. This creates the side of the filter material inlet and outlet chambers for the material to be filtered Lubricant.

Bei Brennkraftmaschinen werden üblicherweise Schmieröl­ filter verwendet, die durch Faltung hergestellt werden und deren Anfang und Ende miteinander verbunden werden, so daß ein Endlosfilter entsteht. Diese haben üblicher­ weise eine kreiszylindrische Form. Ein derartiges Filter beschreibt beispielsweise die DE-PS 36 25 764.Internal combustion engines usually use lubricating oil filters are used, which are produced by convolution and the beginning and end of which are connected, so that an endless filter is created. These are more common wise a circular cylindrical shape. Such a filter describes for example DE-PS 36 25 764.

Aufgabe der vorliegenden Erfindung ist es, unter Aus­ nutzung der gegebenen Raumverhältnisse eine Vergrößerung der Filterfläche vorzusehen.The object of the present invention is under use of the given space conditions an enlargement the filter surface.

Diese Aufgabe wird erfindungsgemäß durch die kennzeich­ nenden Merkmale des ersten Anspruchs gelöst. Dadurch, daß keine kreiszylindrischen Filterelemente und Filter­ töpfe mehr verwendet werden sondern viereckige, wird bei nur unwesentlicher Vergrößerung der Grundfläche eine doch erhebliche Vergrößerung der Filterfläche erreicht. Durch die Verwendung einer entsprechend angepaßten Filterkerze können die üblichen Anordnungen der Ein- und Auslaßöffnungen sowie die Durchströmungsrichtung des Schmierstoffilters beibehalten werden. Die weiterhin vorgesehenen Längsrippen auf der Filtertopfinnenseite dienen dazu, ein Ausbauchen des Filterelementes zu verhindern, welches aufgrund der geänderten Filter­ geometrie eher eintritt.This object is inventively characterized by nenden features of the first claim solved. Thereby, that no circular cylindrical filter elements and filters  Pots are used more than square ones, is used for only insignificant enlargement of the base area but achieved a substantial increase in the filter area. By using an appropriately adapted Filter candle can the usual arrangements of the one and Outlet openings and the flow direction of the Lubricant filter are maintained. The continue provided longitudinal ribs on the inside of the filter bowl serve to bulge the filter element prevent which due to the changed filter geometry rather occurs.

Die Weiterbildung nach Anspruch 2 dient zur Stützung des Filterelementes. Eine derartige Anordnung ist bei kreiszylindrischen Filterkerzen allgemein üblich.The development according to claim 2 serves to support the Filter element. Such an arrangement is in circular cylindrical filter cartridges common.

Im folgenden wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels näher dargestellt.In the following, the invention is based on a preferred Embodiment shown in more detail.

Es stellen dar:They represent:

Fig. 1 einen Querschnitt durch das erfindungsgemäß aufgebaute Schmierstoffilter; Fig. 1 is a cross sectional view of the present invention constructed Schmierstoffilter;

Fig. 2 einen Querschnitt durch das Schmierstoffilter nach Fig. 1. FIG. 2 shows a cross section through the lubricant filter according to FIG. 1.

Fig. 1 zeigt einen Querschnitt durch ein Schmierstoffil­ ter 1, welches zum Reinigen von Schmieröl einer Brenn­ kraftmaschine geeignet ist. Das Schmierstoffilter 1 besteht aus einem einseitig offenen Filtertopf 2, der in seinem unteren Bereich einen Flansch 3 zum Befestigen an dem Gehäuse der nicht näher dargestellten Brennkraft­ maschine aufweist. In dem Filtertopf 2 ist ein Filter­ element 4 eingesetzt. Dieses besteht aus gefaltetem Filtermaterial, dessen Faltstellen mit 5 und 6 bezeich­ net sind. Verschlossen wird der Filtertopf 2 von einem Deckel 7, welcher von einer zentralen Schraube 8 gehal­ ten wird. Das Filterelement 4 weist zur Stützung an der Faltkante 6 ein umlaufendes Lochblech 9 auf. Der Aufbau des Filterelementes 4 entspricht dem üblicher Filter­ kerzen mit der Ausnahme, daß sein Querschnitt nicht kreiszylindrisch sondern viereckig ist. Fig. 1 shows a cross section through a lubricant ter 1 , which is suitable for cleaning lubricating oil of an internal combustion engine. The lubricant filter 1 consists of a filter cup 2 open on one side, which has a flange 3 in its lower region for fastening to the housing of the internal combustion engine, not shown. In the filter bowl 2 , a filter element 4 is used. This consists of pleated filter material, the folds of which are denoted by 5 and 6 . The filter bowl 2 is closed by a cover 7 which is held by a central screw 8 . The filter element 4 has a circumferential perforated plate 9 on the folded edge 6 for support. The structure of the filter element 4 corresponds to the usual filter candles with the exception that its cross-section is not circular cylindrical but square.

Sichtbar wird dies in Fig. 2, die einen Schnitt anhand der Schnittlinie II-II in Fig. 1 zeigt. Wie aus Fig. 2 unschwer zu erkennen ist, ist durch die Verwendung eines viereckigen Filterelementes mit gerundeten Kanten eine wesentliche Vergrößerung der Filterfläche ohne wesent­ liche Vergrößung der Grundfläche des Filterelementes 4 gegeben.This is visible in FIG. 2, which shows a section on the basis of the section line II-II in FIG. 1. As can easily be seen from FIG. 2, the use of a square filter element with rounded edges gives the filter area a substantial increase without enlarging the base area of the filter element 4 .

Um das Filterelement 4 in dieser Form zu halten, sind auf der Innenseite 10 des Filtertopfes 2 Stützrippen 11 angeordnet. Dargestellt sind in Fig. 2 nur zwei Stütz­ rippen. Selbstverständlich sind diese Stützrippen 11 auf jeder Seite angeordnet. Ihre Anzahl richtet sich nach der Seitenlänge der geraden Seiten des Filtertopfes und damit des Filterelementes.In order to keep the filter element 4 in this shape, 2 support ribs 11 are arranged on the inside 10 of the filter bowl. Only two support ribs are shown in Fig. 2. Of course, these support ribs 11 are arranged on each side. Their number depends on the side length of the straight sides of the filter bowl and thus of the filter element.

Das Filterelement 4 kann in üblicher Weise durch Öffnen des Deckels 7 herausgenommen und gegen ein neues Fil­ terelement bei Verschmutzung gewechselt werden.The filter element 4 can be removed in the usual way by opening the lid 7 and replaced with a new fil terelement when dirty.
