Abstract

Crank case venting filters are generally composed of a perforated housing having a filter material arranged therein. Oil separated off drains off on the inner wall of the perforated housing. It is disadvantageous that gases flowing in the wake constantly entrain draining oil in the filter material, as a result of which the filter separation efficiency is markedly decreased. According to the invention, it is proposed to assign a collar, directed into the housing, to each inflow orifice, as a result of which a separation of the path of the draining oil from the flow path of the entering gases is created. Entrainment of oil by leakage gases flowing in the wake is avoided. Filter for separating out atomized liquids from a flowing gaseous medium. <IMAGE>

Description

Die Erfindung betrifft einen Filter zum Ausscheiden verne­ belter Flüssigkeiten aus einem strömenden, gasförmigen Medium, insbesondere zum Ausscheiden von Öl aus den Ent­ lüftungsgasen des Kurbelgehäuses einer Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a filter for excretion verne belter liquids from a flowing, gaseous Medium, especially for the separation of oil from the Ent ventilation gases of the crankcase of an internal combustion engine according to the preamble of claim 1.

Beim Betrieb von Kolbenmaschinen gelangen Leckgase in das Kurbelgehäuse, die in die freie Atmosphäre abgelassen werden oder in das Luftansaugrohr der Kolbenmaschine zu­ rückgeführt werden. Auf seinem Weg durch das Kurbelgehäuse reißt der Leckgasstrom den hier befindlichen Schmierölne­ bel mit sich, wodurch sich die Notwendigkeit ergibt, den Ölnebel nach Austritt aus dem Kurbelgehäuse aus dem Leck­ gasstrom zu entfernen.When operating piston machines, leakage gases get into the Crankcase that drained into the free atmosphere or into the air intake pipe of the piston machine be returned. On its way through the crankcase the leakage gas stream tears the lubricating oils located here with itself, which gives rise to the need for Oil mist after leakage from the crankcase remove gas flow.

Aus der DE-OS 27 19 600 ist ein Filter zum Ausscheiden von Öl aus den Entlüftungsgasen (Leckgase) des Kurbelgehäuses einer Brennkraftmaschine bekannt. Die Entlüftungsgase strömen über die Eintrittsöffnungen in das mit Filtermate­ rial gefüllte Gehäuse des Filters, wobei das durch das Filtermaterial zurückgehaltene Öl an der Innenwandung nach unten abläuft. Bei einer derartigen Ausführungsform hat es sich als nachteilig erwiesen, daß in den Filter nachströ­ mendes Leckgas das auf der Innenwandung herabfließende Öl wieder in das Filtermaterial mitreißt, wodurch der Aus­ scheidungsgrad des Filters vermindert ist.From DE-OS 27 19 600 is a filter for eliminating Oil from the ventilation gases (leak gases) from the crankcase an internal combustion engine known. The vent gases flow through the inlet openings into the filter mate rial-filled housing of the filter, which by the Filter material retained oil on the inner wall expires below. In such an embodiment it has  proved to be disadvantageous that flow into the filter leakage gas the oil flowing down on the inner wall back into the filter material, causing the out degree of separation of the filter is reduced.

Der Erfindung liegt die Aufgabe zugrunde, einen Filter nach dem Oberbegriff des Anspruchs 1 derart weiterzubil­ den, daß ein Mitreißen des bereits abgeschiedenen, flüssi­ gen Mediums durch nachströmende Gase verhindert ist.The invention has for its object a filter to continue to educate according to the preamble of claim 1 that the entrainment of the already separated, liquid medium is prevented by inflowing gases.

Die Aufgabe wird nach den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The task is performed according to the characteristic features of the Claim 1 solved.

Durch die Anordnung von in das Gehäuse des Filters gerich­ teter Kragen um jede Eintrittsöffnung erfolgt eine Tren­ nung des an der Wandung herablaufenden Öls vom Strömungs­ weg einströmender Gase. Das Öl läuft im "Windschatten" der Kragen von einströmenden Gasen ungehindert an der Wandung des Gehäuses zur Sammelstelle hinab.By arranging in the filter housing The collar around each entry opening has a door Oil from the flow flowing down the wall away flowing gases. The oil runs in the "slipstream" of the Incoming gas collar on the wall unhindered the housing down to the collection point.

Vorteilhaft weist jede Eintrittsöffnung einen Kragen auf, der insbesondere beim Stanzen der Eintrittsöffnungen ge­ bildet ist.Each inlet opening advantageously has a collar, the ge especially when punching the inlet openings forms is.

Weitere Merkmale der Erfindung ergeben sich aus der Be­ schreibung und der Zeichnung, in der das im folgenden beschriebene Ausführungsbeispiel der Erfindung dargestellt ist.Further features of the invention result from the Be spelling and the drawing in which the following Described embodiment of the invention is.

Es zeigt:It shows:

Fig. 1 Eine Ansicht eines teilgeschnittenen Filters, Fig. 1 is a view of a partially cut filter,

Fig. 2 eine vergrößerte Innenansicht einer Eintrittsöffnung des Filters, Fig. 2 is an enlarged interior view of an inlet opening of the filter,

Fig. 3 eine Ansicht von innen auf die Gehäusewandung des Filters. Fig. 3 is a view from the inside of the housing wall of the filter.

Der in Fig. 1 dargestellte Filter besteht aus einem be­ cherförmigen Gehäuse 1, dessen Wandung zum Boden hin ko­ nisch verjüngt verläuft und an ihrer tiefsten Stelle eine Abflußleitung 10 aufweist. Die Wandung des Gehäuses weist eine Vielzahl von Eintrittsöffnungen 4 auf, die in umlau­ fenden Reihen angeordnet sind. Die Eintrittsöffnungen 4 der einen Reihe sind zu den Eintrittsöffnungen 4 benach­ barter Reihen versetzt angeordnet.The filter shown in Fig. 1 consists of a be cher-shaped housing 1 , the wall of the bottom tapered ko nically and has a drain line 10 at its lowest point. The wall of the housing has a plurality of inlet openings 4 , which are arranged in umlau fenden rows. The inlet openings 4 of the one row are arranged offset to the inlet openings 4 adjacent rows.

Jede Eintrittsöffnung 4 weist einen in das Innere des Gehäuses 1 gerichteten Kragen 5 auf, der vorzugsweise beim Stanzen der Eintrittsöffnungen mit ausgebildet wird. Auf diese Weise ergibt sich ein strömungsgünstiger Übergang von der Wandung 3 zum Kragen 5.Each inlet opening 4 has a collar 5 directed into the interior of the housing 1 , which is preferably formed when the inlet openings are punched. In this way, there is a streamlined transition from wall 3 to collar 5 .

Das Gehäuse 1 ist mit Filtermaterial 2 gefüllt. Das Fil­ termaterial kann ein Metall- oder Kunststoffgestrick sein; es können auch einzelne Partikel oder Teilchen aus Glas oder Glasfaser als Aufschüttung vorgesehen werden.The housing 1 is filled with filter material 2 . The Fil termaterial can be a metal or plastic knitted fabric; individual particles or particles made of glass or glass fiber can also be provided as a fill.

Das in Pfeilrichtung 6 durch die Eintrittsöffnungen 4 einströmende Gas, insbesondere die Entlüftungsgase des Kurbelgehäuses einer Brennkraftmaschine treten nach Durch­ strömen des Filtermaterials 2 in Pfeilrichtung 9 aus dem Filter wieder aus. Das zurückgehaltene Öl läuft auf der Innenseite der Wandung 3 zur Abflußleitung 10 und tropft in Tropfen 7 oder als Ölstrom ab. The gas flowing in through the inlet openings 4 in the direction of the arrow 6 , in particular the ventilation gases of the crankcase of an internal combustion engine, emerge from the filter again after flowing through the filter material 2 in the direction of the arrow 9 . The retained oil runs on the inside of the wall 3 to the drain line 10 and drips in drops 7 or as an oil stream.

Wie in Fig. 3 vergrößert dargstellt, läuft das ausgeschie­ dene Öl in Richtung der Pfeile 8 um die Kragen 5 herum ab, wobei die Kragen 5 um jede Eintrittsöffnung 4 einen "Wind­ schattenbereich" schaffen, wodurch eine echte Trennung des Strömungswegs der einströmenden Gase vom Abflußweg des Öls geschaffen ist. Ein Mitreißen bereits abgeschiedenen Öls durch einströmende Gase ist vermieden, so daß beim Durch­ strömen des Filtermaterials 2 ein hoher Abscheidungsgrad erreicht wird.As shown in Fig. 3 enlarged, the ejected oil runs in the direction of the arrows 8 around the collar 5 , the collar 5 creating a "wind shadow area" around each inlet opening 4 , whereby a real separation of the flow path of the inflowing gases from Drainage path of the oil is created. An entrainment of already separated oil by inflowing gases is avoided, so that when the filter material 2 flows through, a high degree of separation is achieved.
