Abstract
The invention discloses an automobile gas exhaust silencer which comprises a shell, a gas inlet pipe and a gas exhaust pipe. A first partition and a second partition are arranged in the shell and partitions the interior of the shell into three cavities including the first cavity, the second cavity and the third cavity in sequence. One end of the gas inlet pipe communicates with the second cavity; the other end of the gas inlet pipe penetrates through the first cavity to the outside of the shell; one end of the gas exhaust pipe communicates with the second cavity; and the other end of the gas exhaust pipe penetrates through the third cavity to the outside of the shell. The automobile gas exhaust silencer further comprises a sleeve arranged in the third cavity. The outer circumferential face of the gas exhaust pipe is sleeved with the sleeve. A fourth cavity is formed between the gas exhaust pipe and the sleeve. A plug used for stop flowing of airflow is arranged inside the gas exhaust pipe. The portions, located at the two sides of the plug, of an inner cavity of the gas exhaust pipe communicate with the fourth cavity correspondingly. The automobile gas exhaust silencer is simple and compact in structure and small in occupied space; and high-frequency noise in automobile exhaust gas can be effectively eliminated through mutual flowing of airflow in the gas exhaust pipe and the fourth cavity.
