Silencer and method for manufacturing the same

Abstract

The invention relates to a silencer (1), in particular a vehicle silencer, having a continuous pipe (2) as well as a first resonator chamber (14) and a second resonator chamber (15) each surrounding the pipe (2) and being arranged one behind the other, with the shell (3) of the pipe (2) having at least one first opening (7) which opens into the first resonator chamber (14), and at least one second opening, which opens into the second resonator chamber (15). In order to allow a more flexible manufacturability, the resonator chambers (14, 15) are formed from a first housing part (4) and a second housing part (5), each having a shell embodied around an axis, and the length of the shell of the one housing part (4; 5), as seen in axial direction, is at least the half of the length of the other housing part (5; 4), and the housing parts (4, 5) are slid inside each other and overlap their shells at least in parts, and in the overlapping region (6), the shell exterior face (4a) of the first housing part (4) rests against the shell interior face (5b) of the second housing part (5), and in at least the overlapping region (6), the shell exterior face (4a) of the first housing part (4) and the shell interior face (5b) of the second housing part (5) each have a constant cross-section as seen in axial direction, and the housing parts (4, 5) have a recess on each side facing away from the overlapping region (6), which recess the pipe (2) passes through.
