  • Transverse partition for exhaust volume
    Patent number: 6668973
    Abstract: The transverse partition for separating an exhaust volume into two adjacent chambers includes at least one gas flow passage between the two chambers, the gas flow section through the passage being modifiable under drive from the difference between the pressures on the two sides of the partition. The partition comprises a wall pierced by at least one slit defined between two adjacent edges of the wall, which wall is elastically deformable under drive from the difference between the pressures on the two sides of the partition, between a rest position in which wall continuity is ensured, the two edges of the slit being substantially touching, and a deformed position in which the two edges of the slit are spaced apart so as to define said gas-flow passage between them.
