The invention relates to a silencer (1) and a method for manufacturing a silencer (1), in particular a vehicle silencer, having an inner pipe section (2) and at least one resonator chamber (14, 15) embodied outside the pipe section (2), with the shell (3) of the pipe section (2) having at least one opening (7, 8) that connects the interior of the pipe section (2) with the resonator chamber (14, 15). For simplifying the production process as well as for material and weight savings, the shell segments (4, 5, 6) are prefabricated as individual components and the shell of the inner pipe section (2) is formed by assembling the prefabricated shell segments (4, 5, 6), with the shell segments (4, 5, 6) being arranged to be spread along the circumference of the pipe and extend in axial direction from a first connecting piece (11) to a second connecting piece (12) each, and first ends (9) of the shell segments (4, 5, 6) are connected with the first connecting piece (11) and second ends (10) of the shell segments (4, 5, 6), lying opposite the first ends (9), being connected with the second connecting piece (12).
Silencer (1), in particular a vehicle silencer, having an inner pipe section (2) and at least one resonator chamber (14, 15) embodied outside the pipe section (2), with the shell (3) of the pipe section (2) having at least one opening (7, 8) that connects the interior of the pipe section (2) with the resonator chamber (14, 15), wherein the shell (3) of the inner pipe section is composed of at least three shell segments (4, 5, 6) arranged to be adjacent along the circumference of the pipe, which shell segments extend from a first connecting piece (11) to a second connecting piece (12) each, with first ends (9) of the shell segments (4, 5, 6) being connected with the first connecting piece (11) and second ends (10) of the shell segments (4, 5, 6), arranged opposite the first ends (9), being connected with the second connecting piece (12).
Method for manufacturing a silencer (1), in particular a vehicle silencer, having an inner pipe section (2) and at least one resonator chamber (14, 15) embodied outside the pipe section (2), with the shell (3) of the pipe section (2) having at least one opening (7, 8) that connects the interior of the pipe section (2) with the resonator chamber (14, 15), wherein the shell segments (4, 5, 6) are prefabricated as individual components, and wherein the shell of the inner pipe section (2) is formed by assembling the prefabricated shell segments (4, 5, 6), with the shell segments (4, 5, 6) being arranged to be spread along the circumference of the pipe and extending in axial direction from a first connecting piece (11) to a second connecting piece (12) each, and wherein first ends (9) of the shell segments (4, 5, 6) are connected with the first connecting piece (11), and second ends (10) of the shell segments (4, 5, 6), lying opposite the first ends (9), are connected with the second connecting piece (12).
