 bis zur Schwelle 10 hochgesaugt, von wo aus sie über die gleichzeitig als Luftspeicher dienende Fallei- tung 11 in den Filterraum 5 gelangt. 



   Besonders empfiehlt es sich, die Zuführungsleitung 1 so in den Aufnahmeraum 2 münden zulassen, dass eine gedachte Verbindung der Einmündungen von Überbrückungsleitung und Zuführungsleitung eine möglichst kleine horizontale Komponente aufweist und somit die über die   Zufilhrungsleitung   eintreten- den Luftblasen der   Überbrückungsleitung   8 zugeführt werden. 



   Sehr zweckmässig ist auch, wenn die Einmündung der Zuführungsleitung 1 in den Aufnahmeraum 2 nicht direkt neben der Mündung der Steigleitung 9 vorgesehen ist, damit nicht bei Saugbetrieb der Brenn- stoff noch vor Füllung des Aufnahmeraumes 2 sofort in die Steigleitung 9 gesaugt wird. Nachdem aus
Platzgründen jedoch die Steig-und Zuführungsleitung unmittelbar nebeneinander liegen, wird deshalb., wie auch in der Zeichnung dargestellt, vorgeschlagen, die Zuführungsleitung 1 noch etwas in den Auf- nahmeraum hineinragen zu lassen. 



   Selbstverständlich ist die Erfindung nicht auf das dargestellte Ausführungsbeispiel beschränkt, sondern kann unter Anwendung der mit ihr gegebenen Lehre in verschiedenster Weise abgewandelt werden. 



   PATENTANSPRÜCHE : 
1. Vorrichtung zum Filtern von Flüssigkeiten, insbesondere Brennstoffen, bei der die Flüssigkeit aus einem Aufnahmeraum durch ein gegenüber diesem höher gelegenes Filter in einen hinter dem Filter liegenden Filterraum gefördert wird und eine das Filter überbrückende Leitung vorgesehen ist, dadurch gekennzeichnet, dass die das Filter (6) überbrückende Leitung (8) über eine Schwelle (10) geführt ist, welche höher als die obere Begrenzung des hinter dem Filter befindlichen Filterraumes (5) liegt, wobei der Schwellenwiderstand im normalen Betrieb grösser als der Filterwiderstand ist.

 <Desc / Clms Page number 2>

 It is sucked up to the threshold 10, from where it reaches the filter space 5 via the trap 11, which also serves as an air reservoir.



   It is particularly advisable to allow the supply line 1 to open into the receiving space 2 in such a way that an imaginary connection of the junctions of the bridging line and the supply line has a horizontal component that is as small as possible and thus the air bubbles entering via the supply line are fed to the bridging line 8.



   It is also very useful if the confluence of the supply line 1 in the receiving space 2 is not provided directly next to the mouth of the riser 9 so that the fuel is not sucked into the riser 9 immediately before the receiving space 2 is filled. After out
For reasons of space, however, the riser and supply line are directly adjacent to one another, it is therefore proposed, as also shown in the drawing, that the supply line 1 protrude somewhat into the receiving space.



   Of course, the invention is not limited to the illustrated embodiment, but can be modified in various ways using the teaching given with it.



   PATENT CLAIMS:
1. A device for filtering liquids, in particular fuels, in which the liquid is conveyed from a receiving space through a filter located higher than this into a filter space located behind the filter and a line bridging the filter is provided, characterized in that the filter (6) bridging line (8) is passed over a threshold (10) which is higher than the upper limit of the filter space (5) located behind the filter, the threshold resistance being greater than the filter resistance in normal operation.

Claims (1)

2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass in die Überbrückungsleitung (8) ein Raum (11) eingeschaltet ist, der mindestens das 1, 5fache, vorzugsweise mehr als das 3fache Volumen der vom Brennstoffaufnahmeraum (2) zur Schwelle (10) geführten Steigleitung (9) besitzt. 2. Device according to claim 1, characterized in that in the bypass line (8) a space (11) is switched on, which is at least 1.5 times, preferably more than 3 times the volume of the fuel receiving space (2) to the threshold (10) Has riser (9). 3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, dass der in die Überbrückungsleitung (8) eingeschaltete Raum (11) aus einem von der Schwelle (10) zum Filterraum (5) führendenleitungsteil besteht, dessen Durchmesser gegenüber dem Durchmesser der Steigleitung (9) grösser ist. 3. Apparatus according to claim 2, characterized in that the space (11) switched into the bridging line (8) consists of a line part leading from the threshold (10) to the filter space (5), the diameter of which is greater than the diameter of the riser line (9) is. 4. Vorrichtung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass der Filterraum (5) ringförmig ist und die Überbrückungsleitung (8) einerseits in diesen ringförmigen Raum und anderseits in den Brennstoffaufnahmeraum (2) mündet. 4. Device according to one of the preceding claims, characterized in that the filter space (5) is annular and the bridging line (8) opens on the one hand in this annular space and on the other hand in the fuel receiving space (2). 5. Vorrichtung nach Anspruch 4, dadurch gekennzeichnet, dass der Filterraum (5) und die Überbrükkungsleitung (8) in einem deckeiförmigen Teil (4) ausgespart sind, der zugleich eine Wand des Aufnahmeraumes (2) bildet. 5. Apparatus according to claim 4, characterized in that the filter space (5) and the bridging line (8) are recessed in a cover-shaped part (4) which at the same time forms a wall of the receiving space (2). 6. Vorrichtung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die Brenn- stoffzuführungsleitung (1) des Aufnahmeraumes (2) in diesen hineinragt. 6. Device according to one of the preceding claims, characterized in that the fuel supply line (1) of the receiving space (2) protrudes into this.
