ABSTRACT:
The device comprises a driving mechanism, disconnectable coupling means, a otor in which is conveyed a toxic gas, and an annular seal clamped between stationary knife-edges on the rotor and movable knife-edges associated with a movable annular support unit. A closure control element consisting of an annular jack causes the annular support unit to move between an inactive position and an active position and conversely. A second control element consisting of a resilient washer applies a complementary force to the annular support unit under the action of withdrawal of the driving mechanism.
