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.

Broad-band resonance silencer, in particular for a motor vehicle engine

An air pipe for motor vehicles, in particular for connecting a hot component to a cold component, is provided. A first connector at a first end of the pipe is provided for securing the pipe in an airtight manner to a hot component and a second connector at a second end of the pipe is provided for securing the pipe in an airtight manner to a cold component. At least one flexible pipe portion is provided between the first and the second connectors. Supporting rings made from a material which is dimensionally stable in relation to the flexible pipe material are provided. The supporting rings surround a free pipe cross section and stabilize the cross-sectional shape of the flexible pipe portion.
