Abstract
The invention relates to a muffler used for an exhaust system. The muffler comprises a main pipeline and bends, the main pipeline comprises at least one air inlet and at least one air outlet, sound absorption materials are filled in the main pipeline, and the bends are communicated with the corresponding air inlets of the main pipeline. By the aid of the bends arranged at the air inlets of the main pipeline, when entering the bends prior to entering the main pipeline, sound waves are pretreated in the bends for muffling and then enter the main pipeline filled with the sound absorption materials for final muffling, so that better muffling effect is achieved. Additionally, the bends are capable of changing the mounting direction of the muffler, so that the muffler is more flexible in application.
