Abstract

A filter arrangement is described, having an upright filter with a filter housing and filter insert for cleaning lubricating oil, in particular in an internal combustion engine, and having a filter base, in which there are located a used oil channel, which opens out into a collection chamber directly below the filter insert, a clean oil channel and a drainage channel which leads downwards away from the collection chamber and in which a spring-loaded shut-off valve is arranged which is influenced by the oil pressure in the collection chamber, and which blocks the connection of the collection chamber to the drainage channel under normal operation and opens it when the filter insert has been removed. In order to remove the lubricating oil during a filter change before the filter insert has been taken out of the collection chamber and thus to prevent escape into the surroundings, the system oil pressure in the collection chamber holds the shut-off valve in the closed position which blocks the connection between the collection chamber and the drainage channel and, in the case of a pressureless collection chamber, the spring holds the shut-off valve in the open position which opens the connection.

Description

Die Erfindung bezieht sich auf eine Filteranordnung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a filter arrangement according to the preamble of claim 1.

Eine derartige Filteranordnung ist aus der DE-OS 34 22 482 bekannt. Bei dieser bekannten Filteranordnung hat das aufwendig gebaute Absperrventil u.a. die Auf­ gabe, bei einem Filterwechsel das Entleeren des Inneren des Filtergehäuses über den Ablaßkanal zu ermöglichen. Dabei wird das Absperrventil jedoch erst durch das Hochheben des Filtereinsatzes geöffnet, das im Sammel­ raum und dem gegebenenfalls zu diesem hin geöffneten Inneren des Filtergehäuses befindliche Öl kann erst während der Herausnahme des Filtereinsatzes in den Ab­ laßkanal abfließen, so daß die Gefahr besteht, daß beim Filterwechsel Öl ins Freie gelangt.Such a filter arrangement is from DE-OS 34 22 482 known. In this known filter arrangement has the elaborately built shut-off valve the on if you change the filter, emptying the inside of the filter housing via the drain channel. However, the shut-off valve is only activated by the Lift up the filter insert that is in the collection room and the one that may be open towards it Oil inside the filter housing can only while removing the filter insert in the Ab drain channel, so that there is a risk that the Filter change oil escapes into the open.

Der Erfindung liegt die Aufgabe zugrunde, eine Filter­ anordnung der eingangs genannten Art mit einem einfach aufgebauten Absperrventil mit sicherer Funktion anzugeben, bei der der Sammelraum und das gegebenenfalls mit diesem verbundenen Innere des Filtergehäuses von Öl entleert werden, ohne daß eine Entfernung des Filtereinsatzes notwendig ist. The invention has for its object a filter arrangement of the type mentioned with a simple to set up the shut-off valve with safe function, where the collection room and if necessary with this connected interior of the filter housing emptied of oil without removing the filter insert necessary is.  

Die Aufgabe ist erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale gelöst.The object is according to the invention in the license plate of claim 1 specified features solved.

Bei der erfindungsgemäß ausgebildeten Filteranordnung öffnet das Absperrventil nach Abbau des Systemöldrucks im Sammelraum die Verbindung zum Ablaßkanal, so daß das Öl aus dem Sammelraum und dem Inneren des Filtergehäuses, sofern es nicht zum Sammelraum hin durch eine Rücklauf­ sperre verschlossen ist, rasch ablaufen kann. Damit kann beim Abschrauben einer sog. Filterpatrone, die als Bau­ einheit von Filtergehäuse und Filtereinsatz auf den Filtersockel aufgeschraubt ist, kein Öl aus dem Sammel­ raum ins Freie gelangen. Aber auch bei einer getrennten Ausführung von Filtergehäuse und Filtereinsatz werden der Sammelraum bereits vor dem Entfernen des Filterein­ satzes und das Innere des Filtergehäuses vor oder während des Entfernens des Filtereinsatzes mit ein­ fachen Mitteln entleert, so daß keine größeren Ölmengen mit der Herausnahme des Filtereinsatzes ins Freie ge­ langen können.In the filter arrangement designed according to the invention opens the shut-off valve after reducing the system oil pressure in the collecting room the connection to the drainage channel, so that the Oil from the collecting chamber and the interior of the filter housing, provided it does not return to the collection room through a return lock is locked, can expire quickly. So that can when unscrewing a so-called filter cartridge, which as a construction unit of filter housing and filter insert on the Filter base is screwed on, no oil from the collector get out into the open. But also with a separate one Execution of filter housing and filter insert the collecting area before removing the filter set and the interior of the filter housing in front or during the removal of the filter insert emptied several times, so that no large amounts of oil ge with the removal of the filter insert outdoors can be long.

Im Patentanspruch 2 sind verschiedene gut geeignete Arten des Absperrventils angegeben.In claim 2, various are well suited Types of shut-off valve specified.

Das im Patentanspruch 3 angegebene Absperrventil stellt eine besonders einfach aufgebaute, die Funktionen sicher erfüllende und große Durchlaßquerschnitte ermöglichende Ausführungsform dar.The shut-off valve specified in claim 3 provides a particularly simple structure that functions safely fulfilling and large passage cross sections Embodiment.

Im folgenden wird die Erfindung anhand zweier in der Zeichnung dargestellter Ausführungsbeispiele näher erläutert. The invention is based on two in the Drawing illustrated embodiments closer explained.  

Dabei zeigt:It shows:

Fig. 1 eine Filteranordnung mit einem als Baueinheit ausgeführten Filter und einem Absperrventil sowie Fig. 1 shows a filter arrangement with a filter designed as a unit and a shut-off valve and

Fig. 2 eine Filteranordnung mit getrenntem Filter­ gehäuse und Filtereinsatz mit dem Absperr­ ventil der Fig. 1 in einem Teilausschnitt in größerem Maßstab. Fig. 2 shows a filter assembly with a separate filter housing and filter insert with the shut-off valve of Fig. 1 in a partial section on a larger scale.

Bei der Filteranordnung der Fig. 1, beispielsweise zur Reinigung des Schmieröls einer nicht dargestellten Brenn­ kraftmaschine, ist das als Baueinheit von Filtergehäuse 1 und Filtereinsatz 2, also als Filterpatrone ausgeführte Filter 3 mittels eines Gewindes 4 schräg stehend auf einen Filtersockel 5 aufgeschraubt. In diesem sind ein Zufuhrkanal 6 für Schmutzöl, der in einen Ringkanal 7 mündet, ein Rücklaufkanal 8 für Reinöl und ein vom Ringkanal 7 ausgehender Ablaßkanal 9 angeordnet. Die Abdichtung zwischen dem Filter 3 und dem Filtersockel 5 erfolgt durch einen radial außerhalb des Ringkanals 7 eingesetzten Dichtring 10. Das bei Betrieb der Brenn­ kraftmaschine unter einem Systemdruck stehende Schmutz­ öl wird vom Ringkanal 7 über eine Rücklaufsperre 11 in einen Schmutzölraum 12 im Inneren des Filtergehäuses 1 gedrückt, von dem es durch den Filtereinsatz 2 in einen Reinölraum 13 und von diesem durch einen zentralen, das Gewinde 4 tragenden Stutzen 14 des Filtersockels 5 in den Rücklaufkanal 8 fließt. In the filter arrangement of FIG. 1, for example combustion engine for cleaning the lubricating oil of an internal, not shown, is the threaded as a unit from the filter housing 1 and filter element 2, so as the filter cartridge filters performed 3 obliquely by means of a thread 4 standing on a filter base 5. In this, a feed channel 6 for dirty oil, which opens into an annular channel 7 , a return channel 8 for pure oil and a discharge channel 9 starting from the annular channel 7 are arranged. The seal between the filter 3 and the filter base 5 is provided by a sealing ring 10 inserted radially outside the ring channel 7 . The dirty oil during operation of the internal combustion engine under a system pressure is pressed from the ring channel 7 via a backstop 11 into a dirty oil chamber 12 inside the filter housing 1 , from which it passes through the filter insert 2 into a clean oil chamber 13 and from this through a central one Thread 4 supporting socket 14 of the filter base 5 flows into the return channel 8 .

Der gesamte Raum zwischen dem Zufuhrkanal 6 und der Rück­ laufsperre 11 einschließlich dem Ringkanal 7 bildet einen Sammelraum 15. Von diesem geht in seinem tiefstgelegenen Bereich der Ablaßkanal 9 aus, an dessen Anfang ein Ab­ sperrventil 16 eingebaut ist, dessen Aufbau und Funktions­ weise im Zusammenhang mit Fig. 2 beschrieben wird.The entire space between the feed channel 6 and the backstop 11 including the ring channel 7 forms a collecting space 15th From this goes in its lowest area of the drain channel 9 , at the beginning of which a shut-off valve 16 is installed, the structure and function of which is described in connection with FIG. 2.

Bei der Filteranordnung der Fig. 2 sind Filtersockel 5 und Filtergehäuse 1 einstückig ausgeführt, wobei letzteres durch einen nicht dargestellten Deckel nach oben ab­ schließbar ist. Beim Filterwechsel wird lediglich der Filtereinsatz 2 nach oben herausgezogen. Der Schmutz­ ölraum 12 und der Sammelraum 15 können durch die am unteren Ende des Filtereinsatzes 2 befestigte Rücklauf­ sperre 11 voneinander getrennt sein, bei ihrem Fehlen kann nicht nur der Sammelraum 15, sondern auch das ge­ samte Innere des Filtergehäuses 1 bei geöffnetem Ab­ sperrventil 16 leerlaufen.In the filter arrangement of FIG. 2, filter base 5 and filter housing 1 are made in one piece, the latter being closable from above by a cover, not shown. When changing the filter, only the filter insert 2 is pulled out upwards. The dirty oil chamber 12 and the collecting chamber 15 can be separated from each other by the return lock 11 attached to the lower end of the filter insert 2 , in the absence of which not only the collecting chamber 15 , but also the entire interior of the filter housing 1 can be idle with the shut-off valve 16 open .

Das Absperrventil 16 der Fig. 2 ist als federbelastetes Tellerventil ausgebildet, das mit einem Schaft 17 in einem Abschnitt des Ablaßkanals 9 geführt ist und beim Aufsitzen seines Ventiltellers 19 auf einen Ventilsitz 20 des Ab­ laßkanals 9 diesen gegen den Sammelraum 15 schließt. Eine an einer Schulter 18 sich abstützende und am Ventil­ teller 19 angreifende Feder 21 sucht das Absperrventil 16 in Offenstellung zu halten, wobei am oberen Rand des Ventiltellers 19 befestigte Abstandhalter 22 durch Anlage an einem im Ablaßkanal 9 befestigten Ring 23 den Hub des Absperrventils 16 nach oben begrenzen. Bei ge­ öffnetem Absperrventil 16 kann das im Sammelraum 15 und bei fehlender Rücklaufsperre 11 das gesamte im Inneren des Filtergehäuses 1 befindliche Öl durch die Lücken zwischen den Abstandhaltern 22, um den Ventilteller 19 herum und durch nutenförmige Ausnehmungen 24 im Schaft 17 in den Ablaßkanal 9 abfließen. Bei sich aufbauendem Öl­ systemdruck im Sammelraum 15 wird durch diesen der Ventil­ teller 19 gegen die Kraft der Feder 21 auf den Ventil­ sitz 20 gedrückt und damit der Ablaßkanal 9 gesperrt, so daß das Öl durch den Filtereinsatz 2 in den Rücklauf­ kanal 8 fließen muß. Bei sich abbauendem Druck im Sammel­ raum 15 nach dem Stillsetzen der Brennkraftmaschine hebt die Feder 21 den Ventilteller 19 vom Ventilsitz 20 ab und das Absperrventil 16 ist wieder geöffnet.The shut-off valve 16 of FIG. 2 is designed as a spring-loaded poppet valve, which is guided with a shaft 17 in a section of the drain channel 9 and when the valve disk 19 is seated on a valve seat 20 from the outlet channel 9, this closes against the collecting space 15 . A on a shoulder 18 supported and on the valve plate 19 engaging spring 21 tries to keep the shut-off valve 16 in the open position, with spacers 22 attached to the upper edge of the valve plate 19 by abutment on a ring 23 fastened in the drain channel 9 to the stroke of the shut-off valve 16 limit above. When the shut-off valve 16 is open, the entire oil located in the interior of the filter housing 1 can flow through the gaps between the spacers 22 , around the valve plate 19 and through groove-shaped recesses 24 in the shaft 17 into the drain channel 9 in the collecting chamber 15 and in the absence of a backstop 11 . When the oil system pressure builds up in the collecting chamber 15 , the valve plate 19 is pressed against the force of the spring 21 on the valve seat 20 by this valve and thus the drain channel 9 is blocked, so that the oil must flow through the filter insert 2 into the return channel 8 . When the pressure in the collecting space 15 decreases after the internal combustion engine has stopped, the spring 21 lifts the valve plate 19 from the valve seat 20 and the shut-off valve 16 is opened again.
