FIELD: engine engineering. SUBSTANCE: silencer has housing 1 with inlet passageway 2, toroidal chambers 3, and outlet passageway 4 mounted in series. The gas enters inlet passageway 2 due to rarefication, flows through toroidal chambers 3 to form vortices that take energy off the gas flow and damp its natural vibration and vibration of vortices interacting with each other. As a result, in outlet passage 4, the noise level of the gas flow, giving the significant amount of energy to vortices, is minimum. EFFECT: enhanced silencing. |
