M FilterkÖrper " M filter body "
Die Erfindung betrifft einen zylindrischen Filterkörper» der insbesondere für die Filterung von Kraftstoff und in fester Verbindung mit einem inneren Stützelement sowie stirnseitigen Abdeckscheiben zum wechselnden Einsetzen in ein Gehäuse vor« ' gesehen ist» ■ The invention relates to a cylindrical filter body "which is seen in particular for the filtration of fuel, and in fixed connection with an inner support element and the end face cover plates for alternate insertion into a housing in front of"'"■
Bekannte Pilterkörper bestehen aus einer Filterstoff-Bahn» die entsprechend der Wandstärke bzw« dem Durchmesser des zylindrischen Filterkörpers maßlieh festgelegt ist« und deren gerade oder aber auf Gehrung geschnittenen Endkanten durch Verleimen zusammengefügt sind» So ergibt sich ein Filtermantel, der auch mehrschichtig ausgebildet werden kann»Well-known pilter bodies consist of a filter fabric web » which is determined according to the wall thickness or the diameter of the cylindrical filter body and whose straight or mitered end edges are joined together by gluing »This results in a Filter jacket, which can also be designed in multiple layers »
Weiterhin sind Filterkörper bekannt» bei denen eine Filzstoff··Furthermore, filter bodies are known »in which a felt material ··
Bahn auf ein gelochtes Standrohr aufgewickelt und die Endkante des Wickele durch eine schmale Metall-Leiste befestigt ist, die nagelartige Yorsprünge aufweist«Web wound onto a perforated standpipe and the end edge of the wrap fastened by a narrow metal strip is that has nail-like projections "
Bei einer ebenfalls für die Kraftstoff-Filterung vielfach zur Verwendung kommenden Ausführung wird der Filtorkürper von einem FiIss zylinder aus in Üblicher Weise gewalktemWith one also for the fuel filtering many times The filter body will be used in the next version felted in the usual way from a fiIss cylinder

Material gebildet* ,Material formed *,
Es wurde nun herausgefunden» daß das Filzmaterial, dessen Herstellung verhältnismäßig kostenaufwendig ist, den Nachteil hat, daß es aufgrund seines Grundstoffes " Reißwolle '· das Erreichen einer genau festlegbaren und einheitlichen Struktur nicht möglich macht« Es mußten daher verhältnismäßig starke Streuungen bezüglich der Durchlässigkeit des Filterkörpers hingenommen werden» Das Filterergebnia hängt auch sehr von der Qualität des verwendeten Filzes ab, deren Einheitlichkeit zu wünschen übrig läßt.It has now been found 'that the felt material, its Production is relatively expensive, has the disadvantage that it is due to its raw material "wool" · making it impossible to achieve a precisely definable and uniform structure «It had to be proportionate strong variations in the permeability of the filter body are accepted »Das Filterergebnia also depends very much on the quality of the felt used, the uniformity of which leaves a lot to be desired.
Die neuzeitliche Filtertechnik fordert immer wieder eine Verbesserung der Filterwirkung eines Filterkörpers und eine Senkung der Herstellungskosten ♦ Die Erfindung hat es sich zur Aufgabe gemacht* einen Filterkörper zu schaffen, dessen Materialaufbau gegenüber üblichem Filz nicht nur wirtschaftlich durchführbar ist, sondern darüber hinaus auch gewährleistet, daß eine vollkommen einheitliche, die Filterwirkung verbessernde Faserstruktur erreicht wird, bei der, auf ein Vergleichsvolumen bezogen, die Anzahl der sich bei Einhaltung einer sehr gleiohmäßigen, vorherbestimmbaren Faserstärke ergebenden Poren wesentlich größer ist als bei Filzmaterial·The modern filter technology demands again and again one Improvement of the filter effect of a filter body and a reduction in manufacturing costs ♦ The invention has made it their business * to create a filter body, the material structure of which is not only economically feasible compared to conventional felt, but also more It also ensures that a completely uniform fiber structure that improves the filter effect is achieved in which, based on a comparative volume, the number of The pores resulting from the predeterminable fiber strength are considerably larger than with felt material
Der erfindungsgemäße Filterkörper kennzeichnet sich durch seine auf einem Nadel-Vlies viskoser Zellwolle beruhende Struktur, wobei die Faserstärke 1,5 bis 10 Denier beträgt.The filter body according to the invention is characterized by its structure based on a needle-punched fleece of viscous rayon, with a fiber thickness of 1.5 to 10 denier.
Die Muster veranschaulichen ein Ausführungsbeispiel des neuen Filterkörpers,The samples illustrate an embodiment of the new filter body,
