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. | |
