METHOD OF CHARGING MAGNETIC-FLUID SHAFT SEAL WITH FLUID UNDER PRESSURE Russian patent published in 2007 - IPC F16J15/43 

Abstract RU 2291339 C2

FIELD: mechanical engineering.

SUBSTANCE: method comprises introducing the magnetic liquid in the zone of scattering fluxes of magnetic field of the seal adjacent to the space between the seal and the shaft and generating a pressure drop at the seal smoothly increasing until the magnetic fluid appears in the space from opposite side of the seal.

EFFECT: enhanced reliability of seal.
