Description

Schalldämpfer für strömende Gase Zusatz zur Anmeldung: L 35759 I a/46 c6 -Auslegeschrift 1240 703 Die Patentanmeldung L 35759 I a/46 c6 (deutsche Auslegeschrift 1240 703) betrifft einen Schalldämpfer für strömende Gase, insbesondere Abgase von Brennkraftmaschinen, mit mindestens einem Ringkanal, dessen Wand nach innen gerichtete Gasdurchtrittsöffnungen aufweist, wobei die Erfindung nach der Hauptpatentanmeldung darauf gerichtet ist, daß die Wand den Ringkanalquerschnitt mit stetiger Krümmung rohrartig umschließt. Der Innenraum des Ringkanals dient als Entspannungsraum für die hindurchströmenden schalltragenden Gase und wirkt schalldämpfend.Silencer for flowing gases Addition to the application: L 35759 I a / 46 c6 -Auslegeschrift 1240 703 The patent application L 35759 I a / 46 c6 (German Auslegeschrift 1 240 703) relates to a silencer for flowing gases, in particular exhaust gases from internal combustion engines, with at least one An annular channel, the wall of which has inwardly directed gas passage openings, the invention according to the main patent application being directed to the fact that the wall encloses the annular channel cross-section with a constant curvature like a tube. The interior of the ring channel serves as a relaxation space for the sound-bearing gases flowing through and has a sound-absorbing effect.

In weiterer Ausgestaltung der Hauptpatentanmeldung kann der Ringkanal auch innerhalb eines Gehäuses angeordnet sein und mit seinem Außenumfang am Gehäusemantel anliegen, wobei die Gasdurchtrittsöffnungen in den Gehäuseinnenraum münden. Hierbei ist daran gedacht, daß der ganze Schalldämpfer außerhalb der Schallquelle angeordnet ist.In a further embodiment of the main patent application, the ring channel can also be arranged within a housing and with its outer circumference on the housing jacket abut, the gas passage openings opening into the interior of the housing. Here It is thought that the entire silencer should be arranged outside the sound source is.

Demgegenüber betrifft die vorliegende Erfindung eine Anordnung, bei der in an sich bekannter Weise die Schallquelle innerhalb eines Gehäuses angeordnet ist, das schalldämpfende Elemente enthält. Diese Anordnung hat nicht nur für Verbrennungsmotoren, sondern z. B. auch für elektrische Druckluftschalter oder für Kompressoren Bedeutung.In contrast, the present invention relates to an arrangement in which is arranged in a manner known per se, the sound source within a housing which contains sound-absorbing elements. This arrangement is not only useful for internal combustion engines, but z. B. also important for electrical compressed air switches or compressors.

Die Zusatzanmeldung bezieht sich demnach ihrer Gattung nach auf einen Schalldämpfer für strömende Gase mit mindestens einem Ringkanal, dessen Wandung den Ringkanalquerschnitt mit stetiger Krümmung rohrartig umschließt und nach innen gerichtete Gasdurchtrittsöffnungen aufweist. Die vorliegende Erfindung liegt darin, daß die Wand wenigstens eines Ringkanals als Außenwandteil eines rohrförmigen Gehäuses ausgebildet ist, das die zu dämpfende Schallquelle umschließt.The additional registration therefore relates to one according to its genre Silencer for flowing gases with at least one ring channel, the wall of which encloses the annular channel cross-section with a constant curvature like a tube and inwards has directed gas passage openings. The present invention resides in that the wall of at least one annular channel as an outer wall part of a tubular housing is designed that encloses the sound source to be damped.

Hiernach wird also die Gehäusewand mindestens zum Teil aus einem oder mehreren rohrartigen Ringkanälen gebildet, wodurch die Wand mit sehr einfachen Mitteln in hohem Maß dagegen gesichert wird, daß sie Schwingungen von der Schallquelle aufnimmt und nach außen abstrahlt.According to this, the housing wall is at least partially made of an or formed several tubular ring channels, making the wall with very simple means is secured to a high degree against the fact that it picks up vibrations from the sound source and radiates outwards.

Ein Ausführungsbeispiel der Erfindung wird im folgenden an Hand der Zeichnung beschrieben, die im Längsschnitt das Ende eines Gehäuses zeigt, das durch einen Rohrring gebildet wird.An embodiment of the invention is described below with reference to the Drawing described, which shows in longitudinal section the end of a housing through a tubular ring is formed.

Das Endstück des Gehäuses 1 eines vorstehend beschriebenen Schalldämpfers umschließt in seinem übrigen Teil eine Schallquelle 13, z. B. einen elektrischen Druckluftschalter, einen Kompressor, eine Gasturbine oder eine Brennkraftmaschine. Das eine Ende des Gehäuses ist durch den Ringkanal 3 gebildet, der entsprechend der Hauptpatentanmeldung als Ringrohr gestaltet ist. An ihn schließt sich an einer Seite der zylindrische Mantel des Gehäuses 1 und an der anderen Seite eine Platte 5 an. Der Ringkanal trägt an seiner mit dem Innenraum 7 des Gehäuses in Verbindung stehenden Wand Gasdurchtrittsöffnungen 9. Mit der Außenluft steht er durch Rohrstutzen 11 in Verbindung.The end piece of the housing 1 of a silencer described above encloses in its remaining part a sound source 13, for. B. an electric Compressed air switch, a compressor, a gas turbine or an internal combustion engine. One end of the housing is formed by the annular channel 3, the corresponding the main patent application is designed as a ring tube. He is followed by one Side of the cylindrical shell of the housing 1 and on the other side a plate 5 at. The ring channel carries on its with the interior 7 of the housing in connection standing wall gas passage openings 9. It stands with the outside air through pipe socket 11 in connection.

Je nach der Art der Schallquelle treten die Gase entweder durch die Rohrstutzen 11 und den Ringkanal in den Innenraum 7 ein oder nehmen den umgekehrten Weg. Die Schallwellen verlaufen dagegen in jedem Fall vom Raum 7 her durch den Ringkanal und die Rohrstutzen 11 nach außen.Depending on the type of sound source, the gases either enter the interior space 7 through the pipe socket 11 and the annular channel or take the opposite route. The sound waves, on the other hand, always run from the room 7 through the annular channel and the pipe socket 11 to the outside.
