KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Der die Erfindung bildende Auspufftopf gehört zu der Gattung, bei welcher die Auspuffgase des Verbrennungsmotors durch Gabelung , des Auspuffrohres gespalten und durch die gleichachsig gegeneinander gerichteten Mündungsstücke der beiden Rohrenden zu unmittelbarem Aufprall gegeneinander geführt werden. Dieser Gedanke ist bisher so ausgeführt worden, daß das Aufeinanderprallen in der freienThe muffler forming the invention belongs to the genus in which the exhaust gases of the internal combustion engine split through the fork, the exhaust pipe and through the coaxially oppositely directed mouth pieces of the two pipe ends to immediate Impact against each other. This thought has so far been carried out that clash in the free ίο Luft erfolgte oder in einer engen Kammer, durch deren gelochte Wände die Gase abflössen und von deren drosselnder Wirkung man eine Schalldämpfung erwartete.ίο was air or in a narrow chamber, the gases flow through their perforated walls and their throttling effect soundproofing was expected. Nach der Erfindung soll dieser Aufprall in einem geschlossenen Gefäß stattfinden, welches für die Ausdehnung und Kühlung Raum bietet, und aus welchem die Gase durch eine Öffnung abfließen, die in der Mittelebene zwischen den beiden Rohrmündungen liegt. Dieses GefäßAccording to the invention, this impact should take place in a closed vessel, which provides space for expansion and cooling, and from which the gases pass through an opening drain, which lies in the middle plane between the two pipe mouths. This vessel ao soll eine Kugelform erhalten, um eine möglichst gleichmäßige radiale Ausdehnung der Gase herbeizuführen, den Gasen eine bequeme Führungsfläche zur Abströmung durch die zentrale Öffnung zu bieten und eine billige und dauerhafte Herstellung zu ermöglichen. Es hat sich gezeigt, daß so mit den einfachsten Mitteln nicht nur eine günstige Schalldämpfung, sondern unerwartet auch eine Vergrößerung der Leistung des Motors gegenüber bekannten Anordnungen, eine erhebliche Abkühlung der Gase und die Beseitigung der Funkenausströmung erreicht wurde. Auch hat sich als zweckmäßig erwiesen, hierbei die ausströmenden Gase in einer an sich bekannten Weise mit kalter Luft zu ^mischen und den Fahrtwind, namentlich bei Flugzeugen und Luftschiffen, zur Zuführung dieser Luft und einer Saugwirkung zu benutzen. Dabei kommt es auf die richtige Größenabmessung an, welche leicht für verschiedene Verhältnisse durch Versuche festzustellen ist.ao should have a spherical shape in order to achieve the most uniform possible radial expansion of the To bring about gases, the gases a comfortable guide surface for outflow through the to offer a central opening and to enable cheap and permanent manufacture. It has been shown that with the simplest means not only a favorable sound absorption, but also unexpectedly an increase in the power of the motor compared to known arrangements, a considerable cooling the gases and the elimination of the spark emission has been achieved. Also has proved to be useful, here the outflowing gases in a known per se Way to mix with cold air and the airstream, especially with airplanes and Airships to use for the supply of this air and a suction effect. Here comes it to the correct size dimension, which can easily be made for different proportions by experimentation is to be determined. In der Zeichnung ist α das Auspuffrohr, welches sich in die Äste α1, α2 gabelt, deren Enden in den Kugeltopf b hineinragen und gegeneinander gerichtet sind. Sie müssen so weit über die Innenfläche der Kugel vorstehen, daß der Abfluß der Gase bequem an der Wand hinter den Mündungsöffnungen zu dem zentralen Rohre erfolgen - kann, gist eine zusätzliche Führungsplatte, welche der gleichmäßigen Ver- -50 teilung der Gesamtströmung in dem Gefäß dient.In the drawing, α is the exhaust pipe which forks into the branches α 1 , α 2 , the ends of which protrude into the ball cup b and are directed towards one another. They must protrude so far over the inner surface of the sphere that the gases can easily flow out of the wall behind the mouth openings to the central pipe - if there is an additional guide plate, which serves to evenly distribute the total flow in the vessel . Patenτ-Anspruch:Patenτ claim: Auspufftopf mit Gegeneinanderführung der Auspuffgase eines Verbrennungsmotors, dadurch gekennzeichnet, daß die Enden der Auspuffrohre in einen Kugeltopf hineinragen, so daß die Gase sich in radialer Richtung möglichst gleichmäßig ausdehnen können, und daß sie an der Wand des Topfes nach einem zentralen Abführungsrohr geleitet werden. Exhaust muffler with the exhaust gases of an internal combustion engine running against each other, characterized in that the ends of the exhaust pipes protrude into a ball pot, so that the gases expand as evenly as possible in the radial direction can, and that they are routed to the wall of the pot after a central discharge pipe.
