Description

Die Erfindung betrifft ein Ölfilter zum Reinigen von Schmieröl nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an oil filter for cleaning Lubricating oil according to the preamble of patent claim 1.

Ein solches Schmierölfilter ist beispielsweise aus DE 34 09 219 A1 bekannt.Such a lubricating oil filter is for example from DE 34 09 219 A1 known.

Gegenüber diesem bekannten Filter besteht die Aufgabe der Erfindung darin, den Verschluß des mit dem Roh­ raum des Filtergehäuses verbindbaren Ableitungskana­ les konstruktiv zu vereinfachen und gleichzeitig eine einfache und sichere Handhabung des Ölfilters beim Wechseln des Ölfilter-Einsatzes zu gewährleisten.The task is compared to this known filter the invention in the closure of the with the raw Space of the filter housing connectable drainage canals to simplify the design and at the same time simple and safe handling of the oil filter Ensure changing the oil filter insert.

Gelöst wird diese Aufgabe durch eine Ausgestaltung des gattungsgemäßen Filters nach den kennzeichnenden Merkmalen des Patentanspruchs 1.This task is solved by a configuration of the generic filter according to the characteristic Features of claim 1.

Mit der Ausführung nach Anspruch 2 soll ein automati­ sches Öffnen des zusätzlichen Ableitungskanales am unteren Ende des Filtergehäuses erreicht werden.With the embodiment according to claim 2 is an automati opening of the additional discharge duct on lower end of the filter housing can be reached.

Bei dem bekannten Ölfilter nach DE-GM 87 14 656 ist der Verschluß des mit dem Rohraum des Filtergehäuses verbindbare Ableitungskanales durch zwei zu dessen Funktion erforderliche Federn recht kompliziert und damit wesentlich kostenaufwendiger als nach der Erfindung aufgebaut. Außerdem fehlen Positioniermittel zum lagegerechten Einbau des Ölfiltereinsatzes beim Ersteinbau sowie beim Filterwechsel.In the known oil filter according to DE-GM 87 14 656 the closure of the with the tube space of the filter housing connectable discharge channel through two to its Function required springs quite complicated and  thus much more expensive than according to the invention built up. Positioning means are also missing for the correct installation of the oil filter insert in the Initial installation and when changing the filter.

Weitere zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand des Anspruchs 3.Further expedient refinements of the invention are the subject of claim 3.

Ein Ausführungsbeispiel ist in der Zeichnung darge­ stellt. Es zeigen An embodiment is shown in the drawing poses. Show it  

Fig. 1 einen Längsschnitt durch ein Öl­ filtergehäuse, Fig. 1 a longitudinal section through the filter housing, an oil,

Fig. 2 einen Schnitt durch das Filterge­ häuse nach Linie II-II. Fig. 2 shows a section through the Filterge housing along line II-II.

In ein Ölfiltergehäuse 1 ist ein ringförmiger Filter­ einsatz 2 eingesetzt. Der Filtereinsatz 2 trennt das Filtergehäuse in einen Rohraum 3 und einen Reinraum 4. Entsprechend den eingetragenen Pfeilen wird der Rohraum 3 mit Öl versorgt, das durch den Einsatz ra­ dial hindurchströmt und den Reinraum 4 gemäß den dor­ tigen Pfeilen verläßt.In an oil filter housing 1 , an annular filter insert 2 is used. The filter insert 2 separates the filter housing into a tube space 3 and a clean room 4 . According to the arrows entered, the raw space 3 is supplied with oil which flows through the insert ra dial and leaves the clean room 4 in accordance with the arrows there.

Zur Trennung zwischen Reinraum 4 und Rohraum 3 ist eine untere Endscheibe 5 des Filtereinsatzes mit einem zentralen Rohr 6 verbunden, das in einen zylindri­ schen Kanal des Filtergehäuses hineinragt, gegen den es mit Hilfe eines radialen Dichtringes 7 gedichtet ist.To separate the clean room 4 and tube space 3 , a lower end plate 5 of the filter insert is connected to a central tube 6 which projects into a cylindrical channel of the filter housing, against which it is sealed with the aid of a radial sealing ring 7 .

Am oberen Ende des Ringfiltereinsatzes 2 ist an eine dortige Endscheibe 8 ein Bypassventil 9 angeformt bzw. an dieser angeordnet.At the upper end of the ring filter insert 2 , a bypass valve 9 is molded onto an end disk 8 there or is arranged thereon.

Ein aus dem Rohraum 3 des Filtergehäuses 1 getrennt herausführender Abflußkanal 10 ist durch einen an die untere Endscheibe 5 des Ringfilterelementes 2 ange­ formten Zapfen 11, der mit einer Radialdichtung 12 versehen ist, dicht verschlossen. A from the tube 3 of the filter housing 1 leading outflow channel 10 is sealed by a to the lower end plate 5 of the ring filter element 2 molded pin 11 , which is provided with a radial seal 12 , sealed.

Damit beim Einsetzen des Ringfilterelementes 2 der Zapfen 11 in die Öffnung des Abflußkanales 10 gezielt eindringen kann, sind das Filtergehäuse 1 einerseits und der ringförmige Filtereinsatz 2 andererseits mit axial ineinandergreifenden aufeinander abgestimmten Nut- und Federmitteln 13 versehen.So that when inserting the ring filter element 2 the pin 11 can penetrate into the opening of the drain channel 10 , the filter housing 1 on the one hand and the annular filter insert 2 on the other hand are provided with axially interlocking, coordinated tongue and groove means 13 .

Verschlossen wird das Filtergehäuse mit einem auf­ schraubbaren Deckel 14. Über einen Schnappverschluß 15 ist in Umfangsrichtung drehbar jedoch axial fi­ xiert der Ringfiltereinsatz 2 an dem Deckel 14 befe­ stigt. Auf diese Weise wird beim Abschrauben des Deckels 14 der Ringfiltereinsatz derart axial nach oben verschoben, daß die Öffnung des Abflußkanales 10 durch den Zapfen 11 freigegeben wird.The filter housing is closed with a screw-on cover 14 . About a snap lock 15 is rotatable in the circumferential direction but axially fi xed the ring filter insert 2 on the cover 14 BEFE Stigt. In this way, when the cover 14 is unscrewed, the ring filter insert is displaced axially upward in such a way that the opening of the drainage channel 10 is released by the pin 11 .
