Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung zur Dämpfung akustischer Schwingungen in einer Brennkammer sowie eine entsprechende Brennkammeranordnung mit der Vorrichtung.
Die Vorrichtung umfasst einen Helmholtz-Resonator (4), der über einen Verbindungskanal (2) mit einer Brennkammer (1) verbunden werden kann. Der Helmholtz-Resonator (4) beinhaltet einen durch Zuführen oder Ablassen eines Fluids über eine Zuleitung (5) im Volumen veränderbaren Hohlkörper (6) oder grenzt derart an diesen an, dass sich das Resonanzvolumen (3) des Helmholtz-Resonators (4) bei einer Änderung des Volumens des Hohlkörpers (6) verändert.
