Abstract
Description
Die vorliegende Erfindung befasst sich mit einem Filter für Flüssigkeiten, bevorzugt Kraftstoffe oder Öle, die unter hohem Druck durch eine im Filter befindliche Filterpatrone gedrückt werden.The present invention is concerned yourself with a filter for Liquids, preferably fuels or oils, under high pressure through a filter cartridge in the filter depressed become.
Aufgabenstellung war eine einfache und preiswerte Lösung zu entwickeln, wobei konstruktiv weitestgehend der Einsatz von Kunststoffen trotz des hohen Druckes im Inneren des Filters zu ermöglichen war. Der untere Teil des Filters sollte möglichst weiterhin aus Metall sein, um robuste Behandlung beim Befestigen an dem Motor bzw. sonstigem Aggregat sicherzustellen.The task was an easy one and inexpensive solution to develop, constructively largely using plastics was possible despite the high pressure inside the filter. The lower part of the filter should continue to be made of metal if possible to be robust handling when attached to the engine or other Ensure the unit.
Bekannte Ausführungen eines derartigen Filters weisen einen sehr großen unteren Filterteil aus Metall auf, der die Patrone nahezu vollständig aufnimmt. Lediglich der kleine obere Teil des Filters, auch Deckel genannt, wurde bisher manchmal aus Kunststoff gefertigt.Known designs of such a filter exhibit a very large lower filter part made of metal, which almost completely receives the cartridge. Only the small upper part of the filter, also called the lid, has sometimes been made of plastic.
Durch die vorgenannte bekannte Konstruktion kann der Deckel des Filters geöffnet werden, ohne dass nennenswert Flüssigkeit ausläuft. Wird die Teilung des Filtergehäuses aus einem Bereich oberhalb der Patrone in einen Bereich darunter konstruktiv verschoben, so würde beim Trennen der beiden Gehäusehälften sofort die oberhalb der Trennstelle befindliche Flüssigkeit auslaufen.By the aforementioned known construction the filter cover can be opened be without any appreciable fluid expires. Will the division of the filter housing from an area above the cartridge to an area below constructively postponed, so would when separating the two housing halves immediately the liquid above the separation point will leak out.
Die erfindungsgemäße Konstruktion erlaubt es, das obere Gehäuseteil so auszuführen, dass es die gesamte Patrone übergreift und weiterhin aus Kostengründen aus Kunststoff zu fertigen ist. Ein Austreten von Flüssigkeit beim Wechsel der Filterpatrone wird verhindert, indem beim Öffnen des Filtergehäuses ein automatisches Ablaufen des Filterinhaltes und damit keine Verschmutzung des Filterumfeldes bei Entnahme der Filterpatrone sichergestellt wird. Erfindungsgemäß wird die Flüssigkeit durch die Rücklaufleitung abgeführt. Die gestellte Aufgabe wird dadurch gelöst, dass das Filtergehäuse aus einem oberen und einem unteren Teil besteht, die sich beim Öffnen gezielt voneinander wegbewegen, wobei bevorzugt jeweils eine normalerweise durch eine Dichtung verschlossene Verbindung zum Rücklauf und eine weitere zur Außenluft freigegeben, d.h. geöffnet werden. Eine weitere Dichtung verhindert das Auslaufen von Flüssigkeit bzw. eine Verschmutzung der Filterumgebung beim öffnen des Filters zum Wechsel der Patrone.The construction according to the invention allows the upper housing part to do so that it covers the entire cartridge and still for cost reasons is to be made of plastic. Leakage of fluid when changing the filter cartridge is prevented by opening the filter housing an automatic drain of the filter content and therefore no contamination of the filter area is ensured when the filter cartridge is removed. According to the liquid through the return line dissipated. The task is solved in that the filter housing an upper and a lower part, which is targeted when opening move away from each other, preferably one each normally sealed connection to the return and a more to the outside air released, i.e. be opened. Another seal prevents liquid from leaking or contamination of the filter environment when opening the filter to change the Cartridge.
