| Zusammenfassung: | The utility model discloses a silencing device for a turbocharger. The silencer comprises an inlet pipe, a conical silencing assembly coaxially connected to the right end of the inlet pipe, a first columnar silencing assembly, a second columnar silencing assembly and an outlet pipe coaxially connected to the right end of the second columnar silencing assembly, wherein the first columnar silencingassembly and the second columnar silencing assembly are sequentially and coaxially connected to the right end of the conical silencing assembly. The conical silencing assembly is used for silencing within the frequency range of 2300 Hz to 4830 Hz, and the first columnar silencing assembly and the second columnar silencing assembly are used for silencing within the frequency range of 460 Hz to 2300Hz. The silencing device is simple and compact in structure, wide in silencing range and large in silencing amount, the transmission loss amplitude in the frequency range of 460 Hz to 4830 Hz reaches20 dB or above, and medium |
