w Plattenförmiger Filtereinsatz für die Ansaugluft von Brennkraftmaschinen w w Plate-shaped filter insert for the intake air of internal combustion engines w

Gegenstand der Erfindung ist ein plattenförmiger Filtereinsatz für die Ansaugluft von Brennkraftmaschinen, bei welchem die Ränder eines aus einer Filterstoffbahn in Zickzack-Faltung quaderartig gestalteten Filterelements in rechteckige Rahmen aus Kunststoff eingebettet sind.The invention relates to a plate-shaped filter insert for the intake air of internal combustion engines, in which the Edges of a filter element made from a filter material web in zigzag folds, cuboid, in rectangular frames are embedded from plastic.

Derartige Filtereinsätze sind z.B. in einer Ausführungsform bekannt, bei welcher dem Filterelement motorseitig ein metallisches Flammschutzsieb vorgeschaltet und in dem Rahmen des Filtereinsatzes festgehalten ist.Such filter inserts are known, for example, in an embodiment in which the filter element is made of metal on the engine side Flame protection screen is connected upstream and held in the frame of the filter insert.

Die Erfindung hat es sich zur Aufgabe gemacht, einen Filtereinsatz mit erheblich verlängerter Standzeit zu schaffen, wobei gleichzeitig die Anbringung eines Flammschutzsiebes entbehrlich gemacht wird.The invention has set itself the task of a filter insert to create with a considerably longer service life, while at the same time attaching a flame retardant screen is made dispensable.

Der erfindungsgemäße Filtereinsatz kennzeichnet sich dadurch, daß das Filterelement aus einem gegen Flammrückstoß unempfindlichen Filterpapier gefertigt ist, und daß auf seine Lufteintrittsfläche eine Matte aus synthetischem Wirrfaservlies als Vorfilter haftend aufgebracht ist.The filter insert according to the invention is characterized in that the filter element consists of an insensitive to flame recoil Filter paper is made, and that a mat made of synthetic random fiber fleece as on its air inlet surface Pre-filter is applied adhesive.

Bei einer vorzugsweisen Ausgestaltung der Erfindung sind die Ränder der Wirrfaservlies-Matte zusammen mit den entsprechenden Rändern des FiIterelements in den Kunststoffrahmenteil an der Lufteintrittsseite eingebettet.In a preferred embodiment of the invention, the edges of the random fiber fleece mat are together with the corresponding Edges of the filter element in the plastic frame part embedded on the air inlet side.

In der Zeichnung, die einen Teillängsschnitt durch den Filtereinsatz darstellt, bezeichnenIn the drawing, a partial longitudinal section through the filter insert represents, denote

Ziffer 1 den einbaufertigen Filtereinsatz,Number 1 the ready-to-install filter insert,

Ziffer 2 das Filterelement aus gegen Flammrückstoß unempfindlichen, gefälteltem Filterpapier,Number 2 the filter element made of insensitive to flame recoil, pleated filter paper,

Ziffer 3 den Kunststoffrahmenteil an der Lufteintrittsseite des Filtereinsatzes,Number 3 the plastic frame part on the air inlet side of the filter insert,

Ziffer 4 die auf das Filterelement 2 aufgebrachte Vorfiltermatte aus synthetischem Wirrfaservlies, und Numeral 4 is the pre-filter mat made of synthetic random fiber fleece that is applied to the filter element 2, and

Ziffer 5 den motorseitigen Kunststoffrahmenteil.Number 5 is the plastic frame part on the engine side.
