The silencer (14) is integrated into a coupling between charging air hose (12) and pressure connection (10) so as to reach into hose and connection. The silencer comprises outer chamber (26) and second outer chamber (30) arranged so chamber (26) engages connection (10) via orifice (8) and chamber (30) engages the hose (12) via orifice (32). The inner pipe (14) comprises a first part as chamber (26) and second part as chamber (30), with parts (16,18) meeting where bent at interface (34) in flanges (38) and here welded together.
