摘要

The passage through a partition (8) in an enclosure, through which a part (10) passes and displaces perpendicularly to the passage direction is sealed by a collar (4). The collar pivots on the partition about an axis (A1), perpendicular to the passage axis, on a support (6) fixed to the partition. The part passes inside the collar. A plate (12) passed through by the part and moving with it during its displacement is sealed by a toroidal joint (30). First and second sealing membranes (14,16) connect one end of the collar to the partition and the other end of the collar to the plate.
