Description
Patentansprüche: 1 Elektrisch leitfähige Filterpatrone bestehend aus einem jeweils gelochten Innen (1)-, Mittel (3)-und Außenrohr (4) mit zwischen diesen Rohren befindlichen Filterschichten und an den Rohrenden angeklebten Patronen-Endscheiben (2), wobei die Rohre (1, 3, 4) und die Endscheiben (2) aus Metall sind und das innere Rohr (1) mit einer der Endscheiben (2) metallisch fest verbunden ist, d a d u r c h g e -kennzeichnet, daß die Rohre(1'3,4) an mindestens einem ihrer Enden von einer zwischen ihnen angeordneten elektrisch leitfähigen in radialer Richtung wirkenden Feder 7) kontaktiert sind. Claims: 1 electrically conductive filter cartridge from a perforated inner (1) -, middle (3) and outer tube (4) with between filter layers located in these tubes and cartridge end caps glued to the tube ends (2), the tubes (1, 3, 4) and the end plates (2) being made of metal and the inner Tube (1) is firmly connected to one of the end disks (2) in a metallic manner, which means that it is c h g e - indicates that the tubes (1'3,4) at at least one of their ends of one between them arranged electrically conductive acting in the radial direction Spring 7) are contacted.
2. Filterpatrone nach Anspruch 1, dadurch gekennzeichnet, daß die Feder (6) nur das Innenrohr (1) und das mittlere Rohr (3) kontaktiert, während das äußere Rohr (4) längsgeschlitzt als radial nach außen federnd ausgebildet ist 3. Filterpatrone nach dem Oberbegriff des Anspruchs 1, dadurch gekennzeichnet, daß das mittlere Rohr (3) in einer der Endscheiben in einer Ringnut (8) eingepreßt ist, während das äußere Rohr (4) längsgeschlitzt als radial nach außen federnd ausgebildet ist. 2. Filter cartridge according to claim 1, characterized in that the Spring (6) only contacts the inner tube (1) and the middle tube (3), while the outer tube (4) is longitudinally slotted and designed to be resilient radially outwards 3. Filter cartridge according to the preamble of claim 1, characterized in that the middle tube (3) is pressed into one of the end plates in an annular groove (8), while the outer tube (4) is longitudinally slotted and designed to be resilient radially outward is.
Die Erfindung betrifft eine elektrisch leitfähige Filterpatrone nach dem Oberbegriff des Patentanspruchs 1. The invention relates to an electrically conductive filter cartridge according to the preamble of claim 1.
Eine derartige Filterpatrone ist z.B. als Ölfeinabscheider bekannt (Prospekt der Firma Purolator 1/80 Ba 3000 mit dem Titel »Baureihe: Ölfeinabscheider; Bauartblatt: 79/000 101). Such a filter cartridge is known, for example, as a fine oil separator (Brochure from Purolator 1/80 Ba 3000 with the title »Series: Fine Oil Separators; Type sheet: 79/000 101).
In bestimmten Einsatzfällen besteht die Forderung, daß eine solche Filterpatrone bezüglich aller ihrer einzelnen aus Metall bestehenden Teile mit absoluter Sicherheit auch unter ungünstigen Betriebsverhältnissen durch elektrischen Kontakt aller Einzelteile untereinander insgesamt elektrisch leitfähig ist. Diese Forderung ist bei der bekannten Ausgestaltung der gattungsgemäßen Filterpatrone nicht immer mit hinreichender Sicherheit erfüllt. Denn eine feste metallische Verbindung ist nur zwischen einer Endscheibe und dem Innenrohr gegeben. Alle übrigen Teile sind in der Regel nur miteinander verklebt Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, durch konstruktiv einfache Mittel eine sichere elektrische Kontakt-Verbindung zwischen den einzelnen Rohren und den Endscheiben herzustellen. In certain applications there is a requirement that such Filter cartridge with respect to all of its individual parts made of metal with absolute Safety even under unfavorable operating conditions thanks to electrical contact of all individual parts is electrically conductive to one another. This requirement is not always in the known configuration of the generic filter cartridge met with sufficient certainty. Because there is a solid metallic connection given only between an end plate and the inner tube. All remaining parts are usually only glued together. Starting from this, the invention is the The object is based on a safe electrical contact connection by structurally simple means between the individual tubes and the end plates.
Gelöst wird diese Aufgabe in erster Linie durch eine Ausbildung der Filterpatrone nach dem kennzeichnenden Merkmal des Anspruchs 1. This task is primarily solved by training the Filter cartridge according to the characterizing feature of claim 1.
Eine abgewandelte Ausgestaltung dieser Maßnahme gibt Anspruch 2 wieder. A modified embodiment of this measure is claim 2 again.
Eine alternative, jedoch von den gleichen Grundüberlegungen ausgehende, Lösung gibt Anspruch 3 wieder. An alternative, but based on the same basic considerations, Solution is claim 3 again.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt Es zeigt F i g. 1 den Ausschnitt eines Längsschnittes durch die Filterpatrone in einem Endscheibenbereich, F i g. 2 und 3 alternative Lösungen in gleicher Darstellungsweise wie in Fig. 1. Embodiments of the invention are shown in the drawing It shows F i g. 1 shows the detail of a longitudinal section through the filter cartridge in an end disk area, FIG. 2 and 3 alternative solutions in the same way of representation as in Fig. 1.
Bei allen Ausführungsbeispielen ist das Innenrohr 1 metallisch fest mit der Endscheibe 2 verbunden. Das mittlere Rohr 3 und das Außenrohr 4 sind mit der Endscheibe 3 bei den Ausführungsbeispielen nach Fig. l und 2 lediglich durch eine Klebeschicht 5 fest verbunden. Bei dem Ausführungsbeispiel nach F i g. 1 erfolgt die kontaktierende Verbindung zwischen den einzelnen Rohren 1, 3 und 4 durch eine Feder 6. Diese Feder 6 ist ein mäanderförmig geformter Metallstreifen. Die Mäanderform kann dabei so gewählt sein, daß die Feder 6 bei der Montage auf das mittlere Rohr 3 federnd aufgesetzt werden kann. In all of the exemplary embodiments, the inner tube 1 is solidly metallic connected to the end plate 2. The middle tube 3 and the outer tube 4 are with the end plate 3 in the exemplary embodiments according to FIGS. 1 and 2 only through an adhesive layer 5 firmly connected. In the embodiment according to FIG. 1 takes place the contacting connection between the individual tubes 1, 3 and 4 by a Spring 6. This spring 6 is a meandering metal strip. The meander shape can be chosen so that the spring 6 during assembly on the middle tube 3 can be put on resiliently.
Bei dem Ausführungsbeispiel nach F i g. 2 ist eine Feder 7 metallisch fest mit dem Rohr 1 verbunden. Der Kontakt zwischen dem äußeren Rohr 4 und der Endscheibe 2 wird dadurch erreicht, daß das Rohr 4 geschlitzt ausgebildet ist und eine radial nach außen gerichtete Federspannung aufweist. Dadurch liegt das äußere Rohr 4 mit sicherem metallischen Kontakt an dem äußeren Rand der Endscheibe 2 an. In the embodiment according to FIG. 2, a spring 7 is metallic firmly connected to pipe 1. The contact between the outer tube 4 and the end plate 2 is achieved in that the tube 4 is slotted and one is radial having outwardly directed spring tension. As a result, the outer tube 4 is with it secure metallic contact on the outer edge of the end plate 2.
Bei der Ausführungsform nach F i g. 3 ist in der Endscheibe 2 eine Ringnut 8 vorgesehen zur Aufnahme des mittleren Rohres 3. Die sichere Kontaktierung zwischen dem Rohr 3 und der Endscheibe 2 erfolgt durch ein nach der Montage erfolgendes zumindest punktweises Andrücken der Seitenflanken der Ringnut 8 an das Rohr 3. In the embodiment according to FIG. 3 is in the end plate 2 a Annular groove 8 provided for receiving the central tube 3. Safe contact between the tube 3 and the end plate 2 is carried out by a post-assembly At least pointwise pressing of the side flanks of the annular groove 8 onto the tube 3.
Die Kontaktierung des Rohres 4 mit der Endscheibe 2 wird hierbei in gleicher Weise erzielt wie bei der Ausführungsform nach F i g. 2.The contact between the pipe 4 and the end plate 2 is shown in FIG achieved in the same way as in the embodiment according to FIG. 2.
