Silencing Apparatus TRIZ Cases

An exhaust valve assembly employs a torsion spring and rotatable shaft to regulate flap opening via gas pressure, eliminating electronic actuators.

A fluid sensor protection assembly uses vertically spaced flow-through openings and a continuous passage to enable unobstructed liquid movement.

A performance monitoring unit calculates mean correlation coefficients between error signals and modelled anti-noise to evaluate adaptive filter status.

An inclined catalyst casing inside a trapezoidal exhaust muffler changes gas flow direction to extend purification length.

A muffler assembly uses a movable butterfly valve to adjust exhaust gas flow resistance within divided chambers.

A cross-pipe exhaust system splits and recombines flows to equalize pressure across cylinder banks.

An auxiliary exhaust pipe vents gases via side outlets when mud or snow blocks the main outlet, preventing system damage.

Internal flow-guiding elements separate exhaust streams to prevent urea deposition on bellows walls, maintaining vibration mobility.

Orienting diffusion alloyed sheet edges inward isolates primary substrates from salt spray and urea, preventing corrosion without complex post-forming coatings.

A vehicle exhaust muffler relocates the spark arrester to an exit communication pipe with a flow path narrowing portion.
