EXHAUST GAS SYSTEM PIPELINE FLEXIBLE CONNECTOR Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used for thermal compensations and compensation of vibrations transmitted from internal combustion engine to exhaust gas system, for reduction of loads and damping of internal and external noise. Proposed device has bellows, bellows travel limiter and damping members. Travel limiter is made of strips or wires. Bellows consist of narrow corrugations and at least one wide corrugation. Ratio of radius R of convex surface of wide corrugation to radius r of convex surface of narrow corrugation is chosen from 1.5 to 2.5. Ratio of radius R₁ of concave surface between wide corrugation and narrow corrugation to radius r₁ of concave surface between narrow corrugations is chosen from 1.0 to 2.2. Damping members for both opposite sides of bellows are arranged at both of support rings. EFFECT: increased service life and reduced operating noise. 8 cl, 3 dwg
