Abstract

Die vorliegende Erfindung betrifft einen Schalldämpfer (3) für eine Abgasanlage (1) einer Brennkraftmaschine, insbesondere in einem Kraftfahrzeug. DOLLAR A Um bei einem vergleichsweise preiswerten Aufbau wenigstens zwei unterschiedliche Frequenzen oder Frequenzbereiche bedämpfen zu können, weist der Schalldämpfer (3) ein Gehäuse (5) auf, in dem zumindest zwei Resonatorkammern (6, 7, 8) voneinander getrennt sind. Von einem Abgas führenden Rohr (4) zweigen in einem Abzweigabschnitt (14) zumindest zwei Abzweigrohre (11, 12, 13) ab, die in verschiedenen Resonatorkammern (6, 7, 8) münden. Dabei bildet die jeweilige Resonatorkammer (6, 7, 8) mit dem zugehörigen Abzweigrohr (11, 12, 13) jeweils einen Helmholtz-Resonator (6-11, 7-12, 8-13), die sich durch unterschiedliche Resonanzfrequenzen voneinander unterscheiden.
