Description

Schalldämpfer für Brennkraftmaschinen Die vorliegende Vorrichtung zur Schalldämpfung beruht auf dem Gedanken, die Auspuffgase mit möglichst einfachen und billigen Mitteln in eine große Anzahl von Teilströmen zu zerlegen, die in Hohlräume eindringen und wieder aus diesen heraustreten, wodurch ihre Energie durch Reibung und Wirbelung gebrochen und ihr Austritt in die Außenluft verzögert wird. Die Vorrichtung besteht darin, daß die Auspuffleitung ganz oder teilweise mit Hohlkugeln oder ähnlichen Hohlkörpern (Ellipsoiden, eiförmigen Körpern) angefüllt wird, welche mit einem oder mehreren Löchern versehen werden.Muffler for internal combustion engines The present device for silencing is based on the idea that the exhaust gases with the simplest possible and cheap means of dividing them into a large number of partial flows, which in cavities penetrate and step out of these again, reducing their energy through friction and eddies are broken and their escape into the outside air is delayed. The device consists in that the exhaust pipe wholly or partially with hollow balls or the like Hollow bodies (ellipsoids, egg-shaped bodies) is filled, which with an or several holes are provided.

Es ist zwar bekannt, die Auspuffleitung mit Steinen anzufüllen, welche ebenfalls geräuschdämpfend wirken sollen; sie haben aber den Nachteil, daß sie großes Gewicht haben und den freien Raum stark verengen, so daß die für die Geräuschdämpfung so wichtige Dehnung in einem größeren Raum beeinträchtigt wird. Demgegenüber bieten die Hohlkugeln den Vorteil größerer Leichtigkeit, geringer Beeinträchtigung des freien Raumes, da nicht nur der Raum zwischen den Kugeln, sondern auch der Raum im Innern der Kugeln für die Dehnung zur Verfügung steht. Auch die ebenfalls bereits vorgeschlagenen Vollkugeln mit einzelnen Bohrungen erzielen keine wesentlich günstigere Wirkung, da der Innenraum solcher Kugeln im Verhältnis zum raumverdrängenden undurchbrochenen Teil der Kugeln zu groß ist. Demgegenüber wird bei den gelochten Hohlkugeln nicht nur ein sehr viel größerer Raum im Innern der Kugeln für die Dehnung zur Verfügung gestellt, sondern es treten auch an den Kanten der Löcher durch den sich nach innen erweiternden Raum Drossel- und Wirbelwirkungen ein, die eine Verzögerung der eindringenden und wieder herausdringenden Gase bedingen. Dadurch und durch die Umwege, welche die Gase sowohl beim Hinundherströmen als auch beim Herumströmen um die Kugeln zurücklegen müssen, wird eine starke Dämpfung des Auspuffgeräusches ohne zu großen Gesamtwiderstand erreicht.It is known to fill the exhaust pipe with stones, which should also have a noise-dampening effect; but they have the disadvantage that they are large Have weight and greatly narrow the free space, so that for the noise attenuation so important stretching in a larger room is affected. In contrast, offer the hollow spheres have the advantage of greater lightness, less impairment of the Free space, since not only the space between the spheres, but also the space is available inside the balls for stretching. Even those already The proposed solid balls with individual bores do not achieve a significantly more favorable one Effect, because the interior space of such spheres in relation to the space-displacing impervious one Part of the balls is too big. In contrast, the perforated hollow spheres do not only a much larger space inside the balls is available for stretching posed, but it also occurs at the edges of the holes through the inward widening space throttling and eddy effects that delay the penetration and cause gases to escape again. Because of that and because of the detours, which the gases cover both as they flow around and around the spheres must, a strong attenuation of the exhaust noise without too great overall resistance achieved.

Man hat es durch die Wahl der Größe der Kugeln und der Größe und Anzahl der Löcher dabei in der Hand, bei geringstem Widerstand eine möglichst große Dämpfung zu erreichen. Die zur Füllung der Auspuffgefäße verwendeten Kugeln können aus verschiedenen Materialien hergestellt werden je nach den Verbrennungsprodukten, welche durch diese Auspuffgefäße austreten sollen. Sie können aus Eisen, Stahl usw. (zweiteilig) oder aus nicht rostenden Materialien, wie Aluminium oder auch aus Porzellan, Glas oder Steingut hergestellt werden.You have it by choosing the size of the balls and the size and number the holes in the hand, with as little resistance as possible attenuation to reach. The balls used to fill the exhaust vessels can be of different types Materials are produced depending on the products of combustion produced by them Exhaust vessels should emerge. They can be made of iron, steel, etc. (two-part) or made of non-rusting materials such as aluminum or porcelain, glass or Earthenware are made.
