FIELD: machine building.
SUBSTANCE: tight seal of the device contains multiple sealing elements installed circumferentially around the central opening. Each component contains the sealing surface looking towards the central opening. The seal also contains chamber intended for sealing component sections installation, and input hole for flowing medium source. The input hole is intended to provide the chamber with flowing medium to create overpressure acting on sections of the sealing components to move the sealing surfaces to the central opening.
