Abstract

Said device comprises a housing in which three or more filters are mounted stepwise one behind another or one above another, apart from the passage of air through the filter the excess air being deflected on impinging against the filters and directed via free passages to the air shaft of the car and being cleaned. An additional, thin filter disc is provided both at the beginning and end of the device. The arrangement makes it possible for the air to be well filtered with the device being as small as possible. The filters can easily be exchanged via a lid provided on the device.

Description

Die Erfindung betrifft ein Gerät für den Luftschacht von Autos, zum Filtern der einströmenden Luft.The invention relates to a device for the air shaft of Cars, to filter the incoming air.

Es sind Filter bekannt, welche in den Luftschacht von Autos eingebaut sind. Diese haben den Nachteil, daß sie sehr stark und in ziemlicher Größe gehalten sein müsssen, um die Luft einigermaßen einwandfrei zu filtern. Auch wird der Luftdurchgang damit zu sehr gebremst und ungewollt vermindert.Filters are known which are in the air shaft of Cars are built in. These have the disadvantage that they must be very strong and fairly large, to filter the air reasonably well. Also will the passage of air is too slow and unwanted reduced.

Aufgabe der Erfindung ist nun, diesen Nachteil zu beseit­ igen. Dies wird dadurch erreicht, daß die Luft über mehrere Kleinfilter geleitet wird, wobei ein Teil der Luft durch die Filter gelangt und ein Teil durch Anprall an die Fil­ ter und anschließender Umleitung über einen freien Durch­ gang, mehrmals Reinigung erfährt, bei kleinsten Filter­ ausmaßen.The object of the invention is now to eliminate this disadvantage own. This is achieved in that the air over several Small filter is passed, some of the air through the filter arrives and a part by impact with the fil  ter and subsequent redirection via a free through corridor, undergoes cleaning several times, with the smallest filter measure.

Zu diesem Zweck ist ein Filtergehäuse vorgesehen, indem drei oder mehr Filter stufenweise übereinander bzw. hin­ tereinander angeordnet sind in geringer Stärke, die den Durchgang der Luft in gewissem Umfang gestatten und gleich­ zeitig die Umleitung des verbleibenden Luftstromes über freie Öffnungen der Filter und des Gehäuses ermöglichen. Dadurch wird die bestmögliche Filterung erreicht, bei kaum gebremstem Luftdurchgang und bei möglichst geringer Größe des Gerätes und damit der Filter.For this purpose, a filter housing is provided by three or more filters step by step or one above the other are arranged one behind the other in low strength, which the Allow air to pass to a certain extent and equal early redirection of the remaining airflow allow free openings of the filters and the housing. This ensures the best possible filtering, with hardly any reduced air passage and the smallest possible size of the device and thus the filter.

Die Zeichnung veranschaulicht das Gerät in beispiels­ weiser Ausführung. Es zeigen:The drawing illustrates the device in example wise execution. Show it:

Fig. 1 einen Längsschnitt, Fig. 1 a longitudinal section,

Fig. 2 einen Querschnitt des Gerätes. Fig. 2 shows a cross section of the device.

Das Gerät besteht aus dem halbzylindrischen oder ähn­ lichen Gehäuse 1, 2, das an der Ober- bzw. Vorderseite einen Deckel 12 hat, der an Scharnieren 13 befestigt und mittels einer Klemmfeder öffenbar und verschließbar ist. Am vorderen Ende des Gehäuses, sowie am hinteren Ende ist je ein dünner Filter 10 bzw. 11 angeordnet, die ein­ schiebbar sind. In gewissem Abstand von denselben sind drei, wenn nötig auch mehrere Filter 8 angebracht, die ebenfalls leicht in das Gehäuse einschiebbar sind und zwischen Ringen 5, 6, 7 ruhen. Die Filter sind treppen­ förmig übereinander oder hintereinander angeordnet und haben jeweils einen freien Durchgang 9, der jeweils um 180 Grad versetzt zum vorhergehenden Durchgang ist. Die Luft strömt durch den dünnen Filter 10 ein, prallt gegen die Fläche des ersten Filters 8 den sie teilweise durchdringt, während ein Teil, zur Verhütung der Stauung abgeleitet wird über den Durchgang 9 und dabei auf den zweiten Filter 8 aufprallt, wo sich dasselbe, wie auch beim folgenden dritten Filter 8 wiederholt. Zuletzt ge­ langt die Gesamtluft durch den dünnen Filter 11 in den Luftschacht des Autos. Zu diesem Zweck ist am Ge­ häuse 1, 2 ein Flansch 3 vorgesehen, der auch als Luft­ zuführer zum Luftschacht des Autos ausgebildet sein kann und zur Befestigung des Gehäuses am Auto dient. Eine Dichtung 4 dient zur Abdichtung zwischen Flansch 3 und Luftzuführer.The device consists of the semi-cylindrical or similar union 1 , 2 , which has a cover 12 on the top or front, which is attached to hinges 13 and can be opened and closed by means of a clamping spring. At the front end of the housing, as well as at the rear end, a thin filter 10 or 11 is arranged, which can be pushed. At a certain distance from the same three, if necessary, several filters 8 are attached, which can also be easily inserted into the housing and rest between rings 5 , 6 , 7 . The filters are arranged in a step-like manner one above the other or one behind the other and each have a free passage 9 , which is in each case offset by 180 degrees to the previous passage. The air flows in through the thin filter 10 , impacts the surface of the first filter 8 which it partially penetrates, while a part, to prevent congestion, is discharged via the passage 9 and thereby impinges on the second filter 8 , where the same as in the following third filter 8 repeated. Finally, the total air reaches through the thin filter 11 in the air duct of the car. For this purpose, a flange 3 is provided on the housing 1 , 2 , which can also be designed as an air supply to the air duct of the car and is used to fasten the housing to the car. A seal 4 serves to seal between the flange 3 and the air supply.

Das Gerät hat trotz geringem Querschnitt hohe Filter­ wirkung, durch die stufenweise Anordnung der Filter.Despite its small cross-section, the device has high filters effect, through the gradual arrangement of the filters.
