Description

In der Leitung für die Ansaugluft von Brenn kraftmaschinen hat man bereits Schalldämpfer in Verbindung mit einem Luftreiniger angeordnet, darunter auch solche, bei denen derReinluftaustrittsstutzen des. Reinigers umgeben von der schalldämpfenden Zwischenkammer an den Ansaugstutzen anschließt. , Die neue Erfindung besteht in Weiterentwicklung dieser Ausbildung darin, .daß. der Reinluftaus.trittsstutzen des als Fliehkraftreiniger ausgebildeten Reinigers in eine zweckmäßig auf dem Gehäuse angeordneten Kammer 5 mündet, aus der der in diese ragende Ansaugstutzen der Maschine absaugt. Das Schalldämpfergehäuse wird damit zu einer unmittelbaren Fortsetzung des Reinigergehäuses über dessen Deckel hinaus.In the line for the intake air of internal combustion engines you have already arranged silencers in connection with an air purifier, underneath also those in which the clean air outlet nozzle of the cleaner is surrounded by the sound-absorbing intermediate chamber connected to the intake manifold. , The new invention consists in the further development of this training in .that. the clean air outlet nozzle of the cleaner designed as a centrifugal cleaner in an expedient on the housing arranged chamber 5 opens, from which the suction port of the machine protruding into this sucks. The muffler housing is thus an immediate continuation of the cleaner housing beyond its cover.

Man kann den Schalldämpfer ferner so ausbilden, daß sein Gehäuse denn Mantel des Fliehkraftluftreinigers mit gleichem Durchmesser fortsetzt, also dessen Verlängerung bildet. Der Luftaustrittsstutzen aus diesem Schalldämpfergehäuse wird nach den baulichen Erfordernissen des Einzelfalles in Verbindung mit den Notwendigkeiten einer guten Schalldämpfung gewählt. Daher kann der Reinluftaustrittsstutzen aus dem Schalldämpfer z. B. seitlich, gerade oder schräg oder auch tangential abgezweigt sein. In allen Fällen ergibt sich durch die unmittelbare Verbindung des Reinluftauslaßstützens mit dem Schalldämpfer eine einfache Bauart, indem nämlich die beiden Vorrichtungen wesentliche Bauteile gemeinsam haben. Ferner trägt das Gehäuse des Fliehkraftabscheiders und auch sein Luftraum beachtlich zur Schalldämpfung bei.You can also train the muffler so that its housing then Coat of the centrifugal air cleaner with the same diameter continues, so its Lengthening forms. The air outlet nozzle from this silencer housing is according to the structural requirements of the individual case in connection with the necessities a good soundproofing chosen. Therefore, the clean air outlet nozzle can come out the muffler z. B. laterally, straight or obliquely or tangentially branched be. In all cases, the direct connection of the clean air outlet results in support with the muffler a simple design, namely by the two devices have essential components in common. Furthermore, the housing of the centrifugal separator carries and its air space also contributes considerably to the soundproofing.

Die Erfindung ist in der Zeichnung in einer Anzähl beispielsweisen Ausführungsformen schematisch dargestellt.The invention is exemplified in the drawing in a number Embodiments shown schematically.

Abb. i ist ein mittlerer Längsschnitt durch eine bevorzugte Ausführungsform; Abb.2 bis 4 sind in der Hauptsymmetrieachse der Anordnung verlaufende Schnitte durch andere Ausführungsformen; Abb. 5 ist eine Draufsicht auf die Ausführung nach Abb. 3. Der Fliehkraftreiniger i mit Rohlufteinlaßstutzen 2 und Staubauslaß 3 ist mit einem Rein:luftaUslaßstutzen 4 versehen. Dieser erweitert sich zu einem Schalldämpfergehäuse 5 mit endgültigem Reinluftauslaß 6. Dieser keinluftauslaß kann in verschiedener Weise angeordnet sein, wie dies die Abb. i bis 5 erkennen lassen. .Fig. I is a central longitudinal section through a preferred embodiment; Fig. 2 to 4 are sections running through the main axis of symmetry of the arrangement other embodiments; Fig. 5 is a top view of the embodiment of Fig. 3. The centrifugal cleaner i with raw air inlet nozzle 2 and dust outlet 3 is with a clean: air outlet nozzle 4 is provided. This expands into a silencer housing 5 with final clean air outlet 6. This no air outlet can be in different Be arranged in a manner as shown in Figs. I to 5. .

Zum Betrieb wird der Fiiehkraftluftreiniger in senkrechter, schräger oder waagerechter Lage an die Ansaugleitung des Motors angeschlossen; die Rohluft tritt durch die Öffnungen. 2 tangential in den oberen: Teil des Abscheiders. i ein. Der Staub wird durch das Fallrohr 3 ausgetragen-, während die Rein, luft durch den Stutzen 4 in den. erweiterten Kanal 5 des. Schalldämpfers; übertritt. In manchen Fällen wird durch diese plötzliche Erweiterung eine willkommene Nachenrtstaubung erreicht werden. Auf alle Fälle tritt eine starke Brechung der Schallwellen ein, weil die Luftsäule im Innern des Schalldämpfers einerseits, das Schalldämpfergehäuse andererseits und schließlich auch die Luftsäule im Innern des Fliehkraftreinigers. und das Gehäuse des Fliehkraftreinigers durchaus verschiedene Eigenfrequenzen haben; alle diese Eigenfrequenzen überlagern die Schallschwingungen der austretenden Reinluft im Sinne einer Schalldämpfung.For operation, the Fiiehkraftluftreiniger is in a vertical, inclined position or in a horizontal position connected to the intake line of the engine; the raw air enters through the openings. 2 tangential to the upper: part of the separator. i a. The dust is discharged through the downpipe 3, while the clean, air through the Nozzle 4 in the. enlarged channel 5 of the silencer; transgresses. In some This sudden enlargement of the falls becomes a welcome night-dusting place can be achieved. In any case there is a strong refraction of the sound waves, because the column of air inside the silencer, on the one hand, is the silencer housing on the other hand and finally also the column of air inside the centrifugal cleaner. and the housing of the centrifugal cleaner have quite different natural frequencies; all of these natural frequencies are superimposed on the sound vibrations of the exiting clean air in terms of sound absorption.
