Claims

[Scope of utility model registration request]

A collar is provided on the rotating shaft, and the shaft sealing liquid passage is made into a two-stage constriction: the gap between the seal ring and the rotating shaft, and the gap between the seal ring and the collar. A shaft sealing device characterized in that the unbalance of the axial fluid force acting on the seal ring is reduced by setting the pressure to an intermediate pressure, and the followability of the seal ring in the radial direction to the rotation axis is improved.
