ENGINE EXHAUST SYSTEM TWO-CHANNEL COMPENSATING DEVICE Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used for compensation of vibrations transmitted from internal combustion engine to exhaust system, for reduction of loads and internal and external noises. Proposed device has two inlet pipelines whose outlet ends are united into outlet pipeline. Two symmetrical bellows are installed in inlet pipelines. Common flange for two inlet pipelines is provided. Inlet ends of inlet pipelines are secured on common flange. Wide gofer of one asymmetrical bellows is arranged closer to common flange than wide gofer of other asymmetrical bellows. According to other design version, additional bellows is installed in outlet pipeline. EFFECT: provision of compensation for vibration longitudinal and radial components, reduction of gas flow fluctuations, decrease of loads, external and internal noise. 7 cl, 5 dwg
