Abstract
A broad-band resonance silencer has an at least two-part housing which is designed to receive an exhaust-or gas-conveying pipe, which defines, with a circumferentially surrounding pipe jacket with acoustic openings formed therein, a pipe interior, wherein the pipe, in its installed position, is enclosed by a damping chamber formed by the housing, which chamber is actively connected to the pipe interior via the acoustic openings, and wherein the housing includes two axially split housing half-shells. In order to broaden the scope of use of such a broad-band resonance silencer, it is proposed that the pipe be designed as an insert which includes a central pipe section with two end-side pipe ends, that the insert be designed such that it can be inserted into the housing half-shells of the housing, and that the broad-band resonance silencer includes at least one acoustic channel.
