    Schmierölfilter,   insbesondere für Brennkraftmaschinen 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 
B. sternförmigen, stirnseitige.tallischen Abdeckscheibe 16 aufgenommen wird. 



   Die Abdeckringscheibe 11 ist mit ihrem zu einer Lippenring-Dichtung 110 gestalteten Innenrand auf 
 EMI2.1 
 verschiebbar gelagert. Die Abdeckringscheibedeckels 3 anliegt. 



   In eine Ausstanzung an der unteren Abdeckscheibe 16 ist eine Blattfeder 17 eingesetzt. Diese Blatt- feder erstreckt sich bis zum Boden 80 des Gehäuses 8 und drückt den Filtereinsatz 13 gegen den Gehäuse- deckel 3, wobei sich der Dichtungs-Ringwulst 14 fest an die Flanschstirnfläche 15 des Gehäusedeckels 3 anlegt. 



   Das Standrohr 10. der Filterkörper 9 und die Äbdeckringscheiben 11 und 16, sowie die Blattfeder 17 bilden eine untrennbare Einheit. 



   Sobald der Druck des durch eine Durchflussöffnung 5 des Gehäusedeckels 3 dringenden Schmieröles die Federkraft der Blattfeder 17 übersteigt, verschiebt sich der Filtereinsatz 13 auf dem Halsansatz 5 und der Dichtungs-Ringwulst 14 hebt sich von der Flanschstirnfläche 15 ab, so dass das Schmieröl dein Filtereinsatz 13 zufliessen und über den hohlen Halsansatz 6 abfliessen kann. 



   Das vom Gehäusedeckel 3, dem Filtereinsatz 13 und der Blattfeder 17 gebildete Ventil   schliesst sich   beim Nachlassen bzw. Entfallen des vom Motorlauf abhängigen Schmierölfliessdruckes.

 EMI1.1
 

 <Desc / Clms Page number 2>

 
B. star-shaped, stirnseiten.tallischen cover plate 16 is added.



   The cover ring disk 11 is open with its inner edge designed to form a lip ring seal 110
 EMI2.1
 movably mounted. The cover ring disc cover 3 rests.



   A leaf spring 17 is inserted into a cutout on the lower cover plate 16. This leaf spring extends to the bottom 80 of the housing 8 and presses the filter insert 13 against the housing cover 3, the annular sealing bead 14 resting firmly against the flange face 15 of the housing cover 3.



   The standpipe 10. the filter body 9 and the cover ring disks 11 and 16, as well as the leaf spring 17 form an inseparable unit.



   As soon as the pressure of the lubricating oil penetrating through a flow opening 5 of the housing cover 3 exceeds the spring force of the leaf spring 17, the filter insert 13 moves on the neck 5 and the sealing ring bead 14 lifts off the flange face 15, so that the lubricating oil reaches your filter insert 13 can flow in and drain through the hollow neck 6.



   The valve formed by the housing cover 3, the filter insert 13 and the leaf spring 17 closes when the lubricating oil flow pressure, which is dependent on the running of the engine, decreases or disappears.

Claims

PATENT CLAIM: Lubricating oil filter, especially for internal combustion engines, with a replaceable filter insert, which consists of a z. B. star-shaped, end-face covers having filter body, which is centered in a cup-shaped filter housing with the inner edge of its upper cover ring disc on a housing cover provided with axial passage openings, and the lower cover disc is supported by a spring against the housing base, characterized in that the in known way as the upper embedding of the filter body (9) serving, Ausplas:

Ischem material existing cover ring disk (11) of the filter insert 13 is designed on its inner edge to form a lip ring seal (110) that can slide on a neck (6) of the flange-like housing cover (3) and near its outer edge a lip ring seal (110) against the flange face (15) of the housing cover has sealing ring bead (14) lying against it, and that a leaf spring (17) supported against the bottom (80) of the filter housing (8) is attached to the lower cover disk (16).
