Abstract
A silencer for reducing and canceling medium- to low-frequency vibration and noise that generate in the reciprocating internal combustion engines and in the reciprocating air compressors. An inlet pipe having many ports perforated therein in the radial direction is inserted in a hollow triangular pole in the lengthwise direction thereof, the gas is blown into the hollow triangular pole, and the pulsating gases reflected by the walls in the hollow triangular pole are caused to collide with each other to cancel the pulsation.
Claims7
A silencer, comprising:
- a hollow triangular pole having end surfaces and a chamber;
- a cylindrical inlet pipe secured to and penetrating through one of the end surfaces of said hollow triangular pole and having a plurality of radial ports opened to the chamber of said hollow triangular pole in one or more sectional surfaces nearly at right angles with an axis of the pipe;
- and
- an outlet pipe secured to and penetrating through the other of the end surfaces of the hollow triangle pole, wherein pulsating gases emitted into said hollow triangular pole from the radial ports of said cylindrical inlet pipe come into collision with one another nearly in same phase on a plane nearly at right angles with the axial direction of said cylindrical inlet pipe.

A silencer, comprising:
- a hollow triangular pole having first and second end walls and side walls defining a chamber;
- a cylindrical inlet pipe penetrating through the first end wall of the hollow triangular pole, the inlet pipe having a plurality of radial ports opened to the chamber of the hollow triangular pole in a direction orthogonal to an axial direction of the inlet pipe such that gases emitted into the hollow triangular pole from the radial ports collide with one another substantially in a substantially same phase on a plane substantially orthogonal to the axial direction of the inlet pipe;
- and
- an outlet pipe secured to the second end wall and having an opening connected to the chamber to exit the gases.
