FIELD: automotive industry; exhaust silencers. SUBSTANCE: exhaust silencer has cylindrical housing 1 with inlet end face wall 2 and outlet end face wall 3, intake connection 4 partially arranged in housing, and exhaust connection 5 arranged on side surface of housing 1 in zone of outlet end face wall, inner hollow perforated cylinder 6 with end face plug 7 installed with clearance relative to end face wall 3 and embracing intake connection 4 also made perforated and mated through outlet end face with end face plug 7 of cylinder 6. Intake connection 4 and cylinder 6 are installed coaxially relative to each other and with eccentricity relative to housing 1. Made in silencer are holes 8, 9 corresponding to cylinder and intake connection 4 in zone opposite to exhaust connection 5. Space between intake connection 4 and cylinder 6 is divided by zigzag partition 10 to form opposite alternating channels over entire development of outer surface of intake connection 4. Channels connect in pairs perforated holes 8, 9 of intake connection 4 and hollow cylinder 6. EFFECT: enhanced efficiency of noise suppression. 1 dwg |
