Description
Die Erfindung betrifft einen ringförmigen, radial durchströmbaren Gas-Filtereinsatz nach dem Oberbegriff des Patentanspruchs 1 sowie ein teilbares Filtergehäuse mit einem derartigen Filtereinsatz.The Invention relates to an annular, radially flowed through Gas filter insert according to the preamble of patent claim 1 and a divisible filter housing with such a filter cartridge.
Das der Erfindung zugrunde liegende Problem besteht darin, ein relativ flaches Filter zu schaffen, das bei einer großen Filtrationsfläche möglichst wenig Bauraum einnimmt und bei dem insbesondere die Zu- und Abfuhr des zu filternden Gases durch in einer Ebene eng benachbart liegende Öffnungen erfolgen kann.The The problem underlying the invention is a relative To create a flat filter, as little as possible in a large filtration area Bauraum occupies and in particular the supply and discharge of gas to be filtered by in a plane closely adjacent openings can be done.
Gelöst wird dieses Problem in erster Linie durch einen gattungsgemäßen Filtereinsatz mit den kennzeichnenden Merkmalen des Patentanspruchs 1.Is solved this problem primarily by a generic filter cartridge with the characterizing features of claim 1.
Zweckmäßige und vorteilhafte Ausgestaltungen einschließlich eines zur Aufnahme des erfindungsgemäßen Filtereinsatzes geeigneten Gehäuses sind Gegenstand der Unteransprüche.Appropriate and advantageous embodiments including one for receiving the filter insert according to the invention suitable housing are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, bei einem ringförmigen Filtereinsatz erstmalig die Gaszu- bzw. Abfuhr aus dem zentralen Innenraum nicht axial durch die Stirnseiten des Einsatzes vorzunehmen, sondern durch eine den Ringfilterkörper radial durchdringende Öffnung. Um ein flaches, bauraummäßig insbesondere in dem Motorraum eines Kraftfahrzeuges gut unterbringbares Filter zu erhalten, kann der Ringfilterkörper in Achsrichtung mit einer geringen Höhe ausgebildet sein. Eine große Filterfläche lässt sich bei einem solchen Filter durch eine Ausbildung des Ringfilterkörpers aus zick-zack-förmig gefaltetem Bahnenmaterial erreichen.The The invention is based on the general idea of an annular filter insert For the first time the gas supply and discharge from the central interior not axially through the end faces of the insert, but through a the ring filter body radially penetrating opening. To a flat, space-saving in particular in the engine compartment of a motor vehicle well accommodated filter To obtain the ring filter body in the axial direction with a low altitude be educated. A big filter area let yourself in such a filter by a design of the ring filter body of zig-zag folded Reach web material.
Für eine gute Austauschbarkeit in einem Gehäuse, das durch Abheben eines Deckels geöffnet werden kann, kann der Ringfiltereinsatz auf einen Ein- oder Auslaßstutzen des Gehäuses über die radial durch den Filterkörper hindurchgehende Öffnung einfach dicht aufgesteckt werden. Ein Rein- und Rohraum bildet sich in dem geschlossenen Filtergehäuse durch ein Zusammenspiel stirnseitig an dem Filtereinsatz vorgesehener, umlaufender Dichtungen und zugeordneter Dichtflächen an den gegeneinander teilbaren Filtergehäuseinnenflächen aus.For a good Interchangeability in a housing, which can be opened by lifting a lid, the Ring filter insert on an inlet or outlet port of the housing over the radially through the filter body through opening easily be attached tightly. A clean and raw space is formed in the closed filter housing through an interaction frontally provided on the filter cartridge, circumferential seals and associated sealing surfaces on the mutually divisible Filter housing internal surfaces.
Der ringförmige Filtereinsatz kann unterschiedlichste Ringformen, das heißt insbesondere nicht achssymmetrische Formen annehmen. Besonders geeignet ist eine U-förmige Ausbildung, bei der die radiale Durchgangsöffnung im Bereich zwischen den nach außen auslaufenden U-Schenkeln vorgesehen ist. Wichtig ist, dass einerseits ein Ringabschnitt über minde stens etwa 180° gebogen ist und dass andererseits zwischen den Enden des filternden Filtermaterials praktisch lediglich ein Abstand verbleibt, der für die Aufnahme der Durchgangs-Öffnung und deren Anbringung innerhalb eines Verbindungselementes erforderlich ist.Of the annular Filter insert can a variety of ring shapes, that is, especially not assume axisymmetric shapes. Particularly suitable is a U-shaped training, at the radial passage opening in the area between the outside expiring U-legs is provided. It is important that on the one hand a ring section over at least 180 ° bent and on the other hand, between the ends of the filtering filter material practically remains only a distance that for receiving the passage opening and their attachment is required within a connecting element.
Die Stirnseiten des Innenraumes des erfindungsgemäßen Ringfiltereinsatzes können auch ein- oder beidseitig geschlossen ausgeführt sein, wobei die Verschlußbereiche ebenfalls Filtriereigenschaften aufweisen können. Bei stirnseitig von beiden Seiten geschlossenem Filtereinsatz entfällt eine stirnseitige Dichtung gegenüber dem einen Filtereinsatz aufnehmenden Gehäuse. Zu dichten ist dann lediglich die Verbindung zwischen der radialen Durchgangsöffnung des Filterkörpers und eines zur Zu- bzw. Abfuhr von Gas aus dem Filterinnenraum nach außen erforderlichen Anschlusses.The End faces of the interior of the ring filter insert according to the invention can also be executed closed on one or both sides, the closure areas may also have filtration properties. At the front of both Side closed filter insert eliminates a frontal seal across from the housing receiving a filter cartridge. To dense is then only the connection between the radial passage opening of the filter body and one for the supply and removal of gas from the filter interior to the outside required Connection.
Ein erfindungsgemäßer Filtereinsatz kann aus zick-zack-förmig gefaltetem Endlosbahnenmaterial hergestellt werden. Es ist lediglich gefaltetes Bahnenmaterial in einer vorbestimmten Länge abzulängen und in eine Ringform, die speziell eine U-Form sein kann, zu biegen. In dem Bereich, in dem die freien Enden des derart gebogenen Bahnenmaterials aneinandergrenzen, ist ein Verbindungselement mit einer darin vorgesehenen Durchgangsöffnung zur dichten Verbindung der beiden Filterbahnenden anzubringen. Die dichte Verbindung kann in einer besonders zweckmäßigen Weise durch ein einfaches dichtes Einstecken der Filterbahnenden in Schlitze an dem Verbindungselement erfolgen. Derart erzeugbare dichte Ver bindungen sind an sich bekannt, weshalb auf die Erfahrungen bei diesen bekannten Ausführungen zurückgegriffen werden kann.One Filter insert according to the invention can be folded from zig-zag Continuous sheet material can be produced. It's just folded Cut sheet material in a predetermined length and in a ring shape, which may be a U shape in particular, to bend. In the area, in which adjoin the free ends of the thus bent sheet material, is a connecting element with a passage opening provided therein for dense Attach connection of the two filter web ends. The dense connection can in a particularly convenient way by a simple tight insertion of the filter web ends in slots take the connection element. Densable compounds which can be produced in this way are known per se, which is why the experience in these known designs resorted can be.
Bei einem von radial außen nach innen durchströmten Ringfiltereinsatz innerhalb eines Filtergehäuses kann der äußere Strömungsweg volumenmäßig derart ausgelegt werden, dass über die gesamte Strömungslänge eine etwa gleiche Strömungsgeschwindigkeit erzielbar ist.at one from radially outside flowed through inside Ring filter insert within a filter housing, the outer flow path in volume terms be designed that over the entire flow length one about the same flow speed is achievable.
Ein besonders vorteilhaftes Ausführungsbeispiel ist in der Zeichnung dargestellt.One particularly advantageous embodiment is shown in the drawing.
