Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der Gegenstand der Erfindung betrifft einen Schalldämpfer für Kraftmaschinen, bei welchem die beiden Zweigströme der auspuffenden Gase oder Dämpfe auf einander prallen, um das störende Geräusch, welches z. B. bei Explosionskraftmaschinen durch das Auspuffen der Verbrennungsgase verursacht wird, ganz oder theilweise aufzuheben.The object of the invention relates to a muffler for engines, in which the two branch streams of the exhausting gases or vapors collide with one another to produce the disturbing noise, which z. B. in explosion engines by exhausting the Combustion gases is caused to be lifted in whole or in part.

Der bei E (Fig. 1) eintretende Strom der auspuffenden Gase vertheilt sich in zwei Ströme, welche bei F und G ausströmen und in entgegengesetzter Richtung auf einander treffen.The stream of exhausting gases entering at E (Fig. 1) is divided into two streams which flow out at F and G and meet in opposite directions.

Die am Rande der Oeffnungen -F und G entstehenden Schallwellen heben sich auf. In Fig. 2 geschieht dasselbe durch mehrere paarweise gegenüberstehende Oeffnungen gleichzeitig. ■■ .The sound waves generated at the edge of the openings -F and G cancel each other out. In Fig. 2 the same happens through several pairs of opposing openings at the same time. ■■.
