Description

"Mit einem unmittelbar oder mittelbar von einem Standrohr getragenen Filzmantel versehener Filtereinsatz zur Filterung von Kraftstoff o. dglott Das Gebrauchsmuster betrifft einen mit einem unmittelbar oder mittelbar von einem Standrohr getragenen Filzmantel versehenen Filtereinsatz zur Filterung von Kraftstoff o « dgl."With a directly or indirectly supported by a standpipe A filter insert with a felt jacket for filtering fuel or the like. The utility model relates to one with a directly or indirectly supported by a standpipe Felt jacket provided filter insert for filtering fuel or the like.

Bekannt sind Filzkörper, die im Walkverfahren als geschlossene Zylinder hergestellt werden. Durch dieses Verfahren können im Filzkörper unerwünschte Strukturveränderungen erfolgen, und die Herstellung als geschlossener Filzzylinder hat sich außerdem als kostspielig erwiesen.Felt bodies are known which are used in the flexing process as closed cylinders getting produced. This process can result in undesirable structural changes in the felt body take place, and the production as a closed felt cylinder has also proven to be Proven costly.

Deshalb wurde schon vorgeschlagen, den Filzkörper durch Zusammenkleben der Schnittflächen eines aus einer Filzbahn von gewünschter Struktur geschnittenen Materialstückes herzustellen und dabei die senkrechten Schnittflächen radial oder auf Gehrung zusammenzufügen.Therefore it has already been proposed to glue the felt body together of the cut surfaces of a cut from a felt web of the desired structure Manufacture piece of material and thereby the vertical cut surfaces radially or to be mitred together.

Um nun zu verhindern, daß bei Filzkörpern von größerer Wandstärke beim Verformen der Filzbahn Fasern brechen oder aber daß das Gefüge merklich verändert wird, wird gemäß dem Gebrauchsmuster vorgesehen, den Filzmantel aus einer Vielzahl von Lagen zu bilden, die zusammen seine vorgesehene Wandstärke ergeben.In order to prevent that felt bodies of greater wall thickness When the felt web is deformed, fibers break or the structure changes noticeably is provided according to the utility model, the felt cover from a variety to form layers that together give its intended wall thickness.

Hierdurch wird außerdem der Vorteil erzielt, je nach den Betriebsverhältnissen mehrere Lagen verschiedener Struktur vorzusehen. Auch wird erreicht, daß beim Wartungsvorgang nur diejenigen Filzlagen gereinigt bzw. ausgewechselt werden müssen, die tatsächlich völlig verschmutzt sind.This also has the advantage, depending on the operating conditions to provide several layers of different structure. It is also achieved that during the maintenance process only those felt layers need to be cleaned or replaced that actually need to be cleaned are completely dirty.

Es bietet sich ferner Gelegenheit, gegehenenfalls auch außerhalb einer Werkstatt die Wartung vorzunehmen, selbst wenn keine Filzmäntel zum Austauschen zur Hand sind.There is also the opportunity, if necessary also outside of a Workshop to carry out maintenance, even if there are no felt sleeves to replace are at hand.

Nach dem Gebrauchsmuster bildet jede Lage des Filzmantels einen Zylinder, der jeweils mit einem weiteren Filzzylinder zusammensteckbar ist. Für die Filzmäntel kann gleiches oder aber unterschiedliches Material vorgesehen werden.According to the utility model, each layer of the felt jacket forms a cylinder, each of which can be plugged together with another felt cylinder. For the felt coats the same or different material can be provided.

In Ausgestaltung des Gebrauchsmusters kann jede Lage des Filzmantels aus einer Filzstoffbahn von verhältnismäßig geringer Dicke gewickelt werden, wobei das innere Ende der Wicklung an das Standrohr und das äußere Ende an die vorletzte Wickelwindung angeheftet wird. In der Zeichnung sind Ausführungsbeispiele des Gebrauchsmusters dargestellt, und es zeigen Fig. 1 den Längsschnitt durch einen Filtereinsatz, teilweise in Seitenansicht, Fig. 2 einen Querschnitt nach Linie A-B der Fig. 1 bei Ausführung des Filzmantels als Doppelzylinder, Fig. 3 einen Querschnitt nach Linie A-B bei Ausführung des Filzmantels als Wickelkörper, wobei die gewickelte Filzbahn teilweise als volle breite Linie eingezeichnet isto Die einen mittigen Abdichtungsring 1 tragende Abdeckringscheibe 2 nimmt mit ihrem Stegteil 3 ein gelochtes Standrohr 4 auf, das an seinem oberen Ende die zog. durch Verschraubung mit dem Halsteil 5 einer Verschlußschraube 6 verbundene obere Abdeckringscheibe 7 trägt.In an embodiment of the utility model, any layer of the felt jacket are wound from a felt material web of relatively small thickness, wherein the inner end of the coil to the standpipe and the outer end to the penultimate one Wrap is attached. In the drawing are exemplary embodiments of the utility model shown, and Fig. 1 shows the longitudinal section through a filter insert, partially in side view, Fig. 2 shows a cross section along the line A-B of Fig. 1 in execution of the felt jacket as a double cylinder, Fig. 3 shows a cross section along line A-B Execution of the felt jacket as a wound body, with the wound felt web partially is drawn as a full, broad line The one bearing a central sealing ring 1 Cover ring 2 takes with its web part 3 on a perforated standpipe 4, the at its upper end the pulled. by screwing to the neck part 5 of a screw plug 6 connected upper cover ring 7 carries.

Das Standrohr 4 und die obere Abdeckringscheibe 7 sind bei dem Ausführungsbeispiel von einer Gewebehülle 8 überdeckt.The standpipe 4 and the upper cover ring 7 are in the embodiment covered by a fabric cover 8.

An die Verschlußschraube 6 ist eine Scheibe 9 angeheftet, und zwischen dem Außenrand dieser Scheibe und dem Außenrand der unteren Abdeckscheibe 2 wird der Filzmantel 10 gehalten. Der Filzmantel 10 besteht gemäß den Fig. 1 und 2 aus den in Zylinderform gelegten und an ihren Längskanten zusammengefügten Filzplatten 11 und 12 oder aber nach Fig. 3 aus einer in einer Vielzahl von Windungen auf das Standrohr 4 gewickelten Filzbahn 13, wobei deren inneres Ende 14 an das Standrohr und das äußere Ende 15 an die vorletzte Wickelwindung angeheftet, z. B. angeklebt ist. Schutzansprüches 1) Mit einem unmittelbar oder mittelbar von einem Standrohr getragenen Filzmantel versehener Filtereinsatz zur Filterung von Kraftstoff o. dgl., dadurch gekennzeichnet, daß der Filzmantel aus einer Vielzahl von Lagen besteht, die zusammen seine vorgesehene Wandstärke ergebenA disk 9 is attached to the screw plug 6, and between the outer edge of this disc and the outer edge of the lower cover 2 is the felt jacket 10 held. The felt jacket 10 consists of FIGS. 1 and 2 the felt plates laid in a cylinder shape and joined together at their longitudinal edges 11 and 12 or according to FIG. 3 from one in a plurality of turns on the Standpipe 4 wound felt web 13, the inner end 14 of which is attached to the standpipe and the outer end 15 is attached to the penultimate winding turn, e.g. B. glued is. Protection claims 1) With a directly or indirectly from a standpipe worn felt jacket provided filter insert for filtering fuel or the like, characterized in that the felt jacket consists of a plurality of layers, which together result in its intended wall thickness
