Description

Die Erfindung befaßt sich mit einem Auspufftopf unter Verwendung des an sich bekannten Prinzipes der Gabelung und der Gegeneinanderführung des geteilten Gasstromes. Sie besteht insbesondere darin, daß die Austrittsöffnungen, von denen aus der Aufprall der Gase gegeneinander bewirkt wird, schlitzförmig ausgebildet sind, und daß die durch den Aufprall erzielte Gasplatte innerhalb des zylindrischen Aufprallraumes nach dessen Ende zu abwandert. Nach Durchlaufen dieses den Aufprallraum umschließenden zylindrischen Körpers wechseln die Gase ihre Richtung, indem sie den Zylinder überspülen und an dessen Außenwänden entlang ihren Weg in umgekehrter Richtung fortsetzen. Durch diese Anordnung ist es möglich, eine Konstruktion zu schaffen, die einen denkbar einfachen Aufbau besitzt und sich in hervor-The invention relates to a muffler using what is known per se Principles of the bifurcation and the cross-flow of the divided gas flow. It consists in particular that the Outlet openings from which the gases collide with one another, are slot-shaped, and that the gas plate achieved by the impact within of the cylindrical impact space migrates to its end. After going through this cylindrical body enclosing the impact space, the gases change theirs Direction by flushing over the cylinder and along its outer walls Continue in the opposite direction. This arrangement makes it possible to have a To create a construction that has a very simple structure and is in excellent

ao ragender Weise zur Massenfabrikation eignet.particularly suitable for mass production.

Die Wirkungsweise ist folgende:The mode of action is as follows:

Die bei α eintretenden Gase gelangen durchThe gases entering at α get through

die Schlitze b und prallen etwa in der Ebene c zu einer idealen Gasplatte zusammen, die unter der Wirkung der Expansion nach dem Überlaufraum d des Topf es abzieht. Hierselbst wenden die Gase ihre Abblasrichtung und passieren den Zwischenraum e, der zwischen äußerer Wandung und Expansionsgefäßwandung vorgesehen und durch eine Spirale ausgefüllt ist. Die Gase durchlaufen die Spirale und gelangen schließlich über den Auspufftrichter f ins Freie.the slots b and collide approximately in the plane c to form an ideal gas plate which, under the effect of expansion, pulls it off towards the overflow space d of the pot. Here the gases turn their blow-off direction and pass the space e, which is provided between the outer wall and the expansion vessel wall and is filled by a spiral. The gases pass through the spiral and finally reach the open air via the exhaust funnel f.

Durch die spiralförmige Gasführung bzw. durch die Art der geprägten Rippe wird erreicht, daß die Gase bereits in dem Expansionsraum, also unmittelbar nach dem Aus-.tritt aus dem Schlitz, eine rotierende Bewegung eingehen, deren Drehsinn sich nach Überlauf der Gase in der Ebene d auch auf der äußeren Peripherie des geprägten Expansionsraumes ändert. Es findet also durch die Art der Konstruktion eine gegenläufige Bewegung der Gase statt, wobei sich gleichzeitig der Drehsinn derselben ändert. An Stelle der Schlitze können eine Anzahl dicht und reihenförmig nebeneinanderliegender Löcher gewählt werden, die in ihrer Gesamtheit schlitzförmig wirken.The spiral-shaped gas flow and the type of embossed rib ensure that the gases enter a rotating movement already in the expansion space, i.e. immediately after exiting the slot, the direction of rotation of which changes in the plane after the gases have overflowed d also changes on the outer periphery of the embossed expansion space. Due to the nature of the construction, the gases move in opposite directions, while at the same time the direction of rotation of the same changes. Instead of the slots, a number of holes lying tightly next to one another in rows can be selected which, in their entirety, appear to be slot-shaped.
