Abstract
Sealing unit made up of a floating body placed between a stator and a rotor, axially mobile along the stator and carrying sealing joints between a high pressure area and a low pressure area separated by the rotor. Another pair of joints and by, by stopping against rotor when the latter is displaced axially, allows a resultant pressure force to be exerted which moves floating body in the same direction as the rotor to reach a position of balance in which the elastic joints operate in satisfactory manner without being subjected to excessive wear and without breaking the seal.
