<p>A silencer (1) for reducing and cancelling medium- to low-frequency vibration and noise that generate in the reciprocating internal combustion engines and in the reciprocating air compressors. An inlet pipe (2) having many ports (6) perforated therein in the radial direction is inserted in a hollow triangular pole (3) in the lengthwise direction thereof, the gas is blown into the hollow triangular pole (3), and the pulsating gases reflected by the walls in the hollow triangular pole are caused to collide with each other to cancel the pulsation. <IMAGE></p> |
