ENGINE EXHAUST SYSTEM COMPENSATOR Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used for compensation of vibrations transmitted from internal combustion engine to gas exhaust system, and also for reducing the loads and damping internal and external noises. Proposed compensator has bellows and throttling element with holes. Throttling element is made in form of divider consisting of three plates arranged radially relative to bellows. Plates are interconnected on longitudinal axis of bellows and are secured on bellows from gas outlet side. Gofers of bellows differ in width. Plates differing length along longitudinal axis of bellows. Shorter plate has rows of round holes. Holes in middle plate and longer plate are made in form of slots. Number of slots in cross rows of middle plate decreases in direction of gas flow. Number of slots in cross rows of longer plate increases in direction of gas flow. Contour of cross rows with slots for middle plate and longer plate is Δ- type. EFFECT: increased service life, reduced noise. 4 cl, 3 dwg
