A silencer (10) comprising a housing (11), an exhaust pipe (12), and a chamber (17). The housing (11) has a first end part (13a), a second end part (13b), and a conical wall part (14); the exhaust pipe (12) has an air intake (15a) corresponding to the first end part (13a), and an exhaust outlet (15b) corresponding to the second end part (13b). The chamber (17) is formed between the interior surface of the housing (11) and the exterior surface of the exhaust pipe (12). The exhaust pipe (12) extends beyond the first end part (13a) of the housing (11) and is sealed with the first end part (13a). The second end part (13b) of the housing (11) has an opening (16). The exhaust outlet (15b) of the exhaust pipe (12) is arranged within the chamber (17), and a gap is arranged between the exhaust outlet (15b) and the opening (16) of the second end part (13b). The conical wall part (14) of the housing (11) has arranged thereon a vent (18). When the exhaust pipe (12) discharges waste gas, the outside air enters into the chamber (17) via the vent (18), and exits via the opening (16) of the second end part (13b) of the housing (11), thereby cooling the silencer (10). As ventilation cooling is allowed, the operating temperature of the silencer is reduced, and the range of choices for manufacturing materials for the silencer is expanded. |
