Description

  

   <Desc/Clms Page number 1> 
 



  Zu einer Baueinheit vereinigtes Haupt- und Nebenstromfilter 
Die Erfindung betrifft ein zu einer Baueinheit vereinigtes Haupt- und Nebenstromfilter für Schmier- ölfilterung bei konzentrischer Anordnung von zwei zylindrischen, radial durchströmten Filterkörper, die von mit Abstand voneinander angeordneten gelochten Standrohren und an ihren Enden von für beide Fil- terkörper gemeinsamen Abdeckscheiben begrenzt sind. 



   Gegenüber bekannten Filtereinrichtungen dieser Art geht die Erfindung davon aus, ein Haupt-und Ne- benstromfilter zu einem Aggregat für zeitlich begrenzte bzw. einmalige Benützung zusammenzufassen, das in raumsparender Weise in einfache Gehäuse einsetzbar ist und dessen Montage und Demontage beim
Wartungsdienst auch von ungeschulten Kräften durchgeführt werden kann. 



   Die bisher bekannten Stufenfilter mit voneinander trennbaren Einsätzen sind umständlich in der Gestaltung und daher teuer in der Herstellung. Ferner können sie sich als störanfällig erweisen. 



   Diese Nachteile und Unvollkommenheiten werden nach der Erfindung dadurch wirksam behoben, dass die Abdeckscheiben bei ihrer unlösbar formschlüssigen Verbindung mit den gelochten Standrohren den, eine Teilung in Haupt- und Nebenstrom ermöglichenden Hohlraum zwischen den Filterkörpern festlegende, nach innen gerichtete nutenartige Einprägungen aufweisen und mindestens eine der Abdeckscheiben   1m   Bereiche der Einprägungen mit   Durchflussöffnungen versehen   ist, und dass in bekannter Weise der äussere Filterkörper als grossflächiger, z. B. sternförmiger Vorfilter, der innere Filterkörper dagegen als kompakter, tiefenwirksamer Feinfilter ausgebildet ist. 



   In der Zeichnung ist ein Filter als Ausführungsbeispiel des Gegenstandes der Erfindung in einer Hälfte

  Main and bypass flow filters combined into one unit
The invention relates to a main flow and bypass flow filter combined into one structural unit for lubricating oil filtering with a concentric arrangement of two cylindrical, radially flowed through filter bodies which are delimited by spaced apart perforated standpipes and at their ends by cover disks common to both filter bodies.



   Compared to known filter devices of this type, the invention assumes that a main flow and secondary flow filter are combined to form a unit for time-limited or one-time use, which can be used in a space-saving manner in simple housings and its assembly and disassembly during
Maintenance service can also be carried out by untrained personnel.



   The previously known step filters with inserts which can be separated from one another are cumbersome to design and therefore expensive to manufacture. Furthermore, they can prove to be prone to failure.



   These disadvantages and imperfections are effectively remedied according to the invention in that the cover disks, in their non-detachable form-fitting connection with the perforated standpipes, have inwardly directed groove-like embossings and at least one of the cavities between the filter bodies, which enable a division into main and secondary flow Cover disks 1m areas of the embossing are provided with flow openings, and that in a known manner the outer filter body as a large area, e.g. B. star-shaped pre-filter, the inner filter body, however, is designed as a compact, deep-acting fine filter.



   In the drawing, a filter as an embodiment of the subject matter of the invention is in one half
