Description

Sicherheitsvorrichtung an Schlauchfiltern, insbesondere für Schmieröl Die vorliegende Erfindung betrifft eine Sicherungsvorrichtung an schraubenförmig in einem Topf angeordneten Schlauchfiltern für.Safety device on bag filters, especially for lubricating oil The present invention relates to a safety device on helical Bag filters arranged in a pot for.

Flüssigkeiten, welche Filter insbesondere dazu dienen sollen, umlaufende Schmieröle von Brennkraftmaschinen von mitgeführten schwebenden Verunreinigungen zu befreien. Sicherungen an Ölfiltern gegen schädliche tZberdrücke sind bereits bekannt. Die Sicherungsvorrichtung gemäß der Erfindung besteht in einer neuen Ausbildung eines auf Überdruck ansprechenden Sicherheitsventils.Liquids, which filters are to be used in particular, circulating Lubricating oils from internal combustion engines to remove suspended impurities that are carried along to free. Fuses on oil filters against harmful excess pressure are already in place known. The safety device according to the invention consists of a new design a safety valve that responds to overpressure.

In einem vollständig geschlossenen Gehäuse aus Blech ist in an sich bekannter Weise ein in Windungen aufgerollter Schlauch untergebracht, der aus einem schraubenförmig gewundenen Metalldraht besteht, um welchen ein oder mehrere Gewebelagen angeordnet sind, so daß innerhalb der Drahtspirale ein langer Kanal gegebenen Querschnitts gebildet wird. Die von Schwebestoffen zu reinigende, in den Behälter ständig eingepreßte Flüssigkeit dringt durch diesen als Filter arbeitenden Sichlauch von außen nach innen, sammelt sich in dem Kanal und kann gereinigt durch eine Abgangsarmatur abgezogen werden. Wenn im Laufe einer längeren Betriebsdauer durch die mitgeführten Schmutzteile eine Verstopfullg der Filtergewebe eintritt, können sich verschiedene Mängel zeigen, so z. B., daß bei Anwendung des Filters zur Reinigung von Schmieröl von Brennkraftmaschinen der Zufluß des ) iSls Zt ! den Lagern zu gering wird und somit eine Störung der Schmierung eintritt oder schließlich auch, daß in dem Filtertopf zu hohe Drücke auftreten, die zu einem Platzen derselben führen. In a completely closed housing made of sheet metal is in itself known way housed a rolled up hose, which consists of a There is a helically wound metal wire, around which one or more layers of fabric are arranged so that a long channel given cross section within the wire spiral is formed. The one that has to be cleaned of suspended matter and is constantly pressed into the container Liquid penetrates from the outside through this filter tube inside, collects in the channel and can be cleaned and removed through an outlet fitting will. If in the course of a longer period of operation due to the debris carried along If the filter fabric becomes clogged, various defects can appear, so z. B. that when using the filter for cleaning lubricating oil of internal combustion engines the influx of the) iSls Zt! the camps is too low and thus a disruption of the Lubrication occurs or, finally, that too high pressures in the filter bowl occur which lead to a bursting of the same.

Um diesen Mangel zu vermeiden, ist gemäß Erfindung die Sicherungsvorrichtung am Filtertopf vorgesehen, die in der Zeichnung im Schnitt wiedergegeben ist. In order to avoid this deficiency, the safety device is according to the invention provided on the filter bowl, which is shown in section in the drawing.

Hierbei ist die Auslaßarmatur b als Sicherheitsventll ausgebildet. Die in das Schlauchende gesteckte Tülle bt ist von der Fassung b2 umgeben, deren Unterteil außen das Gewinde für die Befestigung in einer Gegenmutter trägt und auf der Innenseite mit einigen Aussparungen bs versehen ist, die in Verbindung mit der Tülle bt in den freien Raum des Topfes ausmündende Kanäle bilden. Diese sind nach oben durch den Flansch der Tülle bt abgedeckt, der seinerseits durch eine Feder b4 in der Fassung bb auf den die Tülle bt tragenden Innenrand von b2 gepreßt wird mit einem gewissen Überdruck gegenüber dem normalen Betriebsdruck im Filter. Wird dieser Oberdruck innerhalb des Topfes infolge Verstopfung des Filters überschritten, so hebt das durch Stutzen a eingeführte unfiltrierte Öl den als Ventilkegel wirkenden Flansch ab und dringt durch b3, die Schlitze in dem auf dem Flansch bt stehenden Rohr b6 (Abb. 2 und 3) und an der Feder bo vorbeiströmend in die Ausgangsöffnung von bs ein. Die Beobachtung, daß ungereinigtes 01 aus dem Filtertopf austritt, läßt also erkennen, daß der Öldruck zu hoch ist, d. h. daß das Filter in seiner Wirkung nachgelassen hat und austauschbedürftig ist. Here, the outlet fitting b is designed as a safety valve. The socket bt inserted into the hose end is surrounded by the socket b2, whose The lower part carries the thread for fastening in a lock nut and on the outside the inside is provided with some recesses bs, which in connection with the Spout bt form channels opening into the free space of the pot. These are after covered above by the flange of the grommet bt, which in turn is covered by a spring b4 in the version bb is pressed onto the inner edge of b2 carrying the grommet bt with a certain overpressure compared to the normal operating pressure in the filter. Will this overpressure inside the pot is exceeded due to clogging of the filter, the unfiltered oil introduced through nozzle a lifts the one that acts as a valve cone Flange off and penetrates through b3, the slots in the one standing on the flange bt Tube b6 (Fig. 2 and 3) and flowing past the spring bo into the outlet opening from bs a. The observation that uncleaned oil emerges from the filter bowl can be thus recognize that the oil pressure is too high, d. H. that the filter in its effect has waned and needs to be replaced.

PATENTANSPRUCH: Sicherheitsvorrichtung an schraubenförmig in einem Filtertopf angeordnezen Schlauchfiltern für Flüssigkeiten, insbesondere für das Schmieröl von Brenri kraftmaschinen, dadurch gekennzeichnea, daß in dem Anschlußstück (b2) der Auslaßleitung eine den Anschluß an den Filterschlauch vermittelnde Tülle (171) als federbelasteter Ventilteller ausgebildet ist, der bei einem Überdruck im Filtertopf ungereinigte Flüssigkeit aus diesem entweichen läßt. PATENT CLAIM: Safety device on helical in one Filter bowl arranged bag filters for liquids, especially for that Lubricating oil from Brenri engines, characterized in that in the connector (b2) the outlet line has a grommet providing the connection to the filter hose (171) is designed as a spring-loaded valve disk which, in the event of overpressure lets uncleaned liquid escape from the filter bowl.
