Abstract
Kraftstofffilter mit einem konzentrischen Aufbau und einem zickzackförmig gefalteten Filterelement (10), wobei ein Mittelrohr (11) konzentrisch zu dem Filterelement (10) vorgesehen ist und dieses Mittelrohr (11) eine Rast- oder Schnappverbindung (19) mit einem Gehäuse (17) aufweist, wobei die Rast- oder Schnappverbindung (19) gleichzeitig die Abdichtung des Mittelrohres (11) zu dem Gehäuse (17) bildet und wobei ein weiteres Filterelement als Coalescer (14) vorgesehen ist und sowohl das Coalescer-Element (14) als auch das Filterelement (10) radial durchströmt sind.A fuel filter with a concentric structure and a zigzag folded filter element (10), wherein a central tube (11) concentric with the filter element (10) is provided and this central tube (11) has a latching or snap connection (19) with a housing (17) wherein the latching or snap connection (19) simultaneously forms the seal of the central tube (11) to the housing (17) and wherein a further filter element is provided as a coalescer (14) and both the coalescer element (14) and the filter element (10) are flowed through radially.

Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile zu vermeiden und einen Kraftstofffilter zu schaffen, der bei einem einfachen Aufbau eine zuverlässige Abdichtung zwischen den einzelnen Flüssigkeitsströmen und den einzelnen Flüssigkeitsbereichen gewährleistet. Diese Aufgabe wird durch die Merkmale des unabhängigen Anspruches 1 gelöst.The invention has for its object to avoid the disadvantages mentioned and to provide a fuel filter, which ensures a reliable seal between the individual liquid streams and the individual liquid areas in a simple structure. This object is solved by the features of independent claim 1.
Offenbarung der ErfindungDisclosure of the invention
Der wesentliche Vorteil der Erfindung ist darin zu sehen, dass eine Rast- oder Schnappverbindung einerseits durch die Abdichtung eines Mittelrohres zu einem Filterkopf bildet, andererseits gleichzeitig die Befestigung des gesamten Kraftstofffilters an dem Filterkopf sicherstellt.The main advantage of the invention is the fact that a latching or snap connection on the one hand by the seal of a central tube forms a filter head, on the other hand at the same time ensures the attachment of the entire fuel filter to the filter head.
Eine Weiterbildung der Erfindung sieht vor, ein Innenrohr innerhalb des Mittelrohres vorzusehen. Dieses hat die Aufgabe, Wasser aus einem Wassersammelraum durch den Kraftstofffilter hindurch dem Filterkopf zuzuführen.A development of the invention provides to provide an inner tube within the central tube. This has the task to supply water from a water collection chamber through the fuel filter through the filter head.
Gemäß einer weiteren Ausgestaltung der Erfindung ist ferner eine Dichtung an dem Filterelement angeordnet, die in unmittelbarem Kontakt mit einer Dichtfläche an dem Filterkopf steht und damit die Abdichtung zwischen Reinflüssigkeitsbereich und Rohflüssigkeitsbereich sicherstellt. Innerhalb des Gehäuses wird der Kraftstofffilte in einer bevorzugten Weise durch eine Verschlussrastung fixiert, die am Innenrohr angeordnet ist und dort in Verbindung mit einer Rastvorrichtung am Gehäuse für eine zuverlässige Verbindung sorgt.According to a further embodiment of the invention, a seal is further arranged on the filter element, which is in direct contact with a sealing surface on the filter head and thus ensures the seal between the clean liquid region and raw liquid region. Within the housing, the fuel filter is fixed in a preferred manner by a locking catch, which is arranged on the inner tube and there in conjunction with a locking device on the housing provides a reliable connection.
Diese und weitere Merkmale sind nicht nur in den Ansprüchen, sondern auch in der Beschreibung und den Zeichnungen beschrieben.These and other features are described not only in the claims but also in the description and the drawings.
