摘要

The housing (2) has a resonance chamber (11) surrounded by a flowable gas guiding channel (10) in a circumferential direction in sections. The gas guiding channel and the resonance chamber communicate with each other via a connection opening, where the resonance chamber exhibits a common wall (12). An end of the resonance chamber leads to an opening at an outer side of the housing, where the opening of the resonance chamber is locked using a connecting piece.
