Abstract

Изобретение позвол ет повысить эффективность шумоглушени и улучшить технологичность. Поток отработавших газов через впускной патрубок 1, первый 14 и второй 15 дополнительные впускные патрубки и второй дополнительный перепускной канал 13 поступает во впускную камеру 4, где скорость газов снижаетс из-за их расширени и наличи пересекающихс потоков. Газы, проход через первый дополнительный перепускной 12 и перепускной 6 каналы, поступают последовательно в промежуточную и выпускную камеры. Причем благодар наличию выходных окон 19 и 8, разделителей, окон 20 и 9 и отражателей газы дел тс на две части и измен ют направление движени , пересека сь при дальнейшем движении внутри камер, при этом значительна часть их энергии гаситс . Далее газы из выпускной камеры через выпускное окно 27 поступают в выпускной патрубок 2 и выбрасываютс в окружающую среду. 2 з.п. ф-лы, 4 ил.The invention makes it possible to increase the efficiency of sound attenuation and improve manufacturability. The exhaust gas flow through the inlet 1, the first 14 and second 15 additional inlet pipes and the second additional bypass 13 enters the inlet chamber 4, where the velocity of the gases decreases due to their expansion and the presence of intersecting flows. Gases, the passage through the first additional bypass 12 and the bypass 6 channels, flow sequentially into the intermediate and exhaust chambers. Moreover, due to the presence of exit windows 19 and 8, separators, windows 20 and 9, and reflectors, the gases are divided into two parts and change the direction of movement, intersecting with further movement inside the chambers, with a significant part of their energy being extinguished. Further, the gases from the outlet chamber through the outlet port 27 enter the outlet port 2 and are released into the environment. 2 hp f-ly, 4 ill.

Claims

Claim

1. A muffler comprising a housing with inlet and outlet nozzles, separated by means of a transverse partition into an inlet and outlet chamber, and a bypass channel connected to the outlet nozzle, made of two stamped half sections and provided with an input and at least two output windows, a separator in in the form of a tongue bent inward and a reflector, characterized in that, in order to increase the efficiency of noise suppression and improve manufacturability, it is equipped with the first and second additional bypass channels, the first and second other additional inlet pipes and a longitudinal partition made at the same time with bypass channels of two stamped half sections and forming an intermediate chamber in the exhaust chamber, the bypass channel being connected to the intermediate and exhaust chambers, the first additional bypass channel being connected to the inlet and intermediate chambers and provided with at least two additional exit windows, a separator in the form of a tongue bent inward and a reflector, the second additional bypass channel is connected to the inlet a special nozzle and an inlet chamber, and the first and second additional inlet nozzles are installed in the area of the inlet chamber.

2. Silencer according to π. 1, characterized in that the housing is made of two half-bodies connected to each other on the periphery.
