Description
Die Erfindung betrifft Verbesserungen von Schalldämpfern, nach Patent 570 630. Die Verbesserungen bestehen darin, daß an Stelle eines spiralförmigen Kanales zwei oder mehrere hinter- oder nebeneinandergeschaltet werden und daß die Teilströme an Stelle je einer vollen Windung nur Teile einer Windung überspringen. Ferner wird ein Teil des Abgasstromes nicht durch die Kanäle geschickt, sondern nur durch den Kern der Spiralen. Dieser vorauseilende Teilstrom übt auf die nachfolgenden Teilströme eine Saugwirkung aus und setzt dadurch den Durchströmungswiderstand der anderen Teilströme herab.The invention relates to improvements in mufflers, according to patent 570,630 Improvements are that instead of a spiral channel two or more be connected in series or next to each other and that the partial flows in place depending only skip parts of a turn in a full turn. Furthermore, part of the The exhaust gas flow is not sent through the channels, but only through the core of the spirals. This leading partial flow exerts a suction effect on the following partial flows and thereby reduces the flow resistance of the other partial flows.
Die vorerwähnten Verbesserungen steigern noch die Dämpfung der Geräusche, und zwar unter Minderung des Leistungsabfalles des Motors. Der Schalldämpfer soll nicht nur bei Verbrennungsmotoren Anwendung finden, sondern auch bei Preßluft werkzeugen u. dgl.The aforementioned improvements increase the attenuation of the noise, namely while reducing the loss of engine power. The muffler is not just supposed to in internal combustion engines use, but also tools for compressed air and the like.
Die Erfindung ist in den Zeichnungen beispielsweise erläutert.The invention is illustrated by way of example in the drawings.

Fig. 4 zeigt einen Querschnitt eines Schall dämpfers mit nebeneinandergelagerten Spiralen. Fig. 4 shows a cross section of a muffler with side by side spirals.
In dem Zylinder 1 sind die beiden spiralförmigen Kanäle 2 und 3 derart hintereinandergeschartet, daß beide Spiralen entgegengesetzten Wicklungssinn haben. Die innere Windung der Spirale 2 weist die zwei Lochreihen 4 und 5 auf, die äußere Windung der Spirale 3 gleichfalls zwei Lochreihen 6 . und 7. Der Boden 8, der beide Spiralen trennt, ist im Kern kegelig gestaltet und durch die aus ihm herausgedrückten Lappen 9 mit Öffnungen versehen.In the cylinder 1, the two are spiral-shaped Channels 2 and 3 arranged one behind the other in such a way that both spirals are opposite Have winding sense. The inner turn of the spiral 2 has the two rows of holes 4 and 5, the outer turn the spiral 3 also has two rows of holes 6. and 7. The bottom 8, which separates the two spirals, has a conical core and provided with openings by the tabs 9 pressed out of it.
Das Abgas tritt durch das Rohr 10 in den Kern der Spirale 2 und zerteilt sich hier in die Teilströme a, -b, c,. d. Teilstrom: a springt sofort in den Kern der Spirale 3 über, während die hmtereinandergesehalteten Teilströme b, c, d die Spirale 2 nach außen durchwandern. Sie. gelangen nach dem die Spirale umgebenden Zylinderraum 11 und treten von hier abermals in die Teilströme e, f, g zerlegt in die Spirale 3. Sie durchwandern, durch die Saugwirkung des Teilstromes α unterstützt, hintereinander den spiralförmigen Kanal 3 von außen nach innen, um schließlich den Schalldämpfer durch die Ableitung 12 zu verlassen. The exhaust gas passes through the pipe 10 into the core of the spiral 2 and is divided here into the partial flows a, -b, c ,. d. Partial flow: a jumps over immediately into the core of the spiral 3, while the partial flows b, c, d , which are mutually separated, migrate through the spiral 2 to the outside. She. reach the space surrounding the spiral cylinder space 11 and withdraw from here again in the partial streams e, f, g decomposed into the spiral 3. wander, α supported by the sucking action of the sub-stream one after the other helical channel 3 from the outside inwards, and finally leave the silencer through the discharge line 12.
Bei dem in Fig. 4 dargestellten Schalldämpfer erfolgt eine Aufteilung des in 10 eintretenden Gases in die Teüströmie«, b, c und nach. Durchwandern der ersten Spirale in die Teilströme d, e. Der Austritt erfolgt aus 12. Will man auch hier eine Ansaugwirkung· erzielen, so ist von der Auspuff-In the case of the silencer shown in FIG. 4, the gas entering 10 is divided into parts b, c and after. Wandering through the first spiral in the partial flows d, e. The exit takes place from 12. If you want to achieve a suction effect here too, the exhaust pipe
leitung· vor dem Eintritt in den S challdämp feieine kleine Abzweigung 13 unmittelbar nach 12 und entlang der Innenkante der Spirale 3 einzuführen, aus der das Gas tangential zu der Spiralendkante austritt, die wieder von einem Teilstrom, der einen direkten Weg nimmt, angesaugt werden. Die Spiralen werden zweckmäßig in einen Mantel aus Asbest o. dgl. eingehüllt und darüber noch ein Blechmantel gelegt. Man kann auch bei dieser Form einen Teilstrom voraus schicken, indem man einen Teil des Abgases direkt in die Spirale 3 am besten tangential einleitet.line · in front of the entry into the silencer small branch 13 immediately after 12 and along the inner edge of the spiral 3 introduce, from which the gas exits tangentially to the spiral end edge, which again from a partial flow that takes a direct route can be sucked in. The spirals will be Expediently wrapped in a jacket made of asbestos or the like and a sheet metal jacket over it placed. You can also send a partial flow ahead in this form by it is best to introduce part of the exhaust gas directly into the spiral 3 tangentially.
