Description

Luftreiniger. Die Erfindung betrifft einen Luftreiniger für Verbrennungskraftmaschinen, dessen wesentliches Merkmal in einer selbsttätigen Sperrung des Lufteintrittes für den Fall besteht, daß kein Filter eingesetzt ist, um zu verhindern, daß durch Nachlässigkeit oder Vergeßlichkeit der Bedienungsmannschaft der Verbrennungsmotor ohne Filter betrieben wird. Beim Herausnehmen des Filters zwecks Reinigung oder Auswechselung wird die Luftzuführung durch ein federbelastetes Ventil geschlossen, das beim Einsetzen des Filters entgegen der Kraft der Feder geöffnet wird.Air cleaner. The invention relates to an air cleaner for internal combustion engines, its main feature in an automatic blocking of the air inlet for in the event that a filter is not inserted to prevent negligence or forgetfulness of the operator operating the internal combustion engine without a filter will. When removing the filter for cleaning or replacement, the Air supply closed by a spring-loaded valve, which is activated when the Filter is opened against the force of the spring.

Die Vorrichtung ist in zwei Abbildungen dargestellt. In Abb. t ist das Filter, das hier ringförmig als Patrone ausgebildet ist, mit a bezeichnet, b ist ein Kolbenschieber, c eine Fejer,-..d...gine ". Siierstange und e eine Schützhaübe. `Züerirnietzen des Filters wird die Schutzhaüb6 e=,entfernt und das Filter a in seine richtige Lage gebracht. Durch sein eigenes Schwergewicht drückt das Filter die Steuerstange d und damit den Kolbenschieber b herunter. Die Feder wird zusammengedrückt. Durch das Herunterdrücken des Kolbenschiebers werden Schlitze, die im Schieber angebracht sind, frei und ermöglichen ein Durchtreten der Luft. Beim Abnehmen des Filters tritt die Federkraft wieder in Tätigkeit und drückt den Kolbenschieber hoch, sperrt somit den Lufteintritt in den Motor. Die Pfeile geben den Weg der Luft an.The device is shown in two figures. In Fig. T is the filter which is annularly designed here as a cartridge, denoted by a, b is a piston slide, c a Fejer, - .. d ... gine "Siierstange and e is an Schützhaübe` Züerirnietzen of the filter.. The protective hoods e =, removed and the filter a brought into its correct position. By its own weight the filter presses the control rod d and thus the piston valve b down. The spring is compressed. By pressing down the piston valve slots are made in the valve are free and allow air to pass through. When the filter is removed, the spring force comes into action again and pushes the piston valve up, thus blocking the entry of air into the engine. The arrows indicate the path of the air.

Abb. a ist eine andere Ausbildungsform. Mit a ist wiederum das Filter bezeichnet, mit b Gier Schieber, mit c die Feder, mit d die Steuer- oder Führungsstange, mit e die Schutzhaube, mit f das Anschlußrohr, mit g der Deckel des Anschlußrohres. Der Schieber ist hier als überwurfsrohr ausgebildet. Im oberen Teile des Anschlußrohres sind rechteckige öffnungen für den Lufteintritt angebracht, desgleichen im überwurfsrohr. Bei nicht eingesetztem Filter verdeckt der untere Teil des überwurfsrohres die Öffnungen des Anschlußrohres. Wird das Filter eingesetzt, so kommt der innere Rand des Filters auf die Ansätze des Anschlußrohres zu ruhen, und durch die Schwere des Filters wird das Anschlußrohr heruntergedrückt. Dadurch kommen die Öffnungen des Anschluß- und überwurfsrohr.es übereinanderzuliegen und geben den Lufteintritt zu dem Inneren der Verbrennungskraftmaschine frei.Fig. A is another form of training. With a again is the filter with b yaw slide, with c the spring, with d the control or guide rod, with e the protective hood, with f the connection pipe, with g the cover of the connection pipe. The slide is designed here as a union tube. In the upper part of the connecting pipe there are rectangular openings for the air inlet, as well as in the union pipe. When the filter is not in place, the lower part of the tube covers the openings of the connecting pipe. When the filter is inserted, the inner edge of the filter comes out to rest on the approaches of the connecting pipe, and by the gravity of the filter will the connecting pipe pressed down. This brings the openings of the connection and überurfsrohr.es lie on top of each other and give the air inlet to the interior the internal combustion engine free.
