Abstract RU 2033534 C1

FIELD: engine engineering. SUBSTANCE: silencer has at least one chamber 1 defined by housing 2 having end face walls 3,4 whereto inlet 5 and outlet 6 branch pipes are secured. The internal outlet sections 7,8 of the branch pipes are positioned in nodal zones of lowest natural resonance modes of gas a space inside the chamber. The silencer is also has perforated casing 10 which is received at least in receiving chamber of the silencer. The casing and walls of housing 2 of the silencer define an air space. The generatrix of casing 10 is parallel to the longitudinal axis of housing 2. The angle length of the cross-section of casing 10 is no less than half angle length of the cross-section of housing 2. EFFECT: enhanced silencing. 3 cl, 7 dwg
