ABSTRACT:
A bi-directional seal for sealing, from the ambient, a pressurized fluid in the interior of a housing fitted with a rotatable shaft. The seal is a non-contact seal which balances hydrostatic and hydrodynamic forces to form a predetermined proper gap between the annular sealing faces of the rotor and the stator. The hydrodynamic forces are primarily a result of the size and configuration of the radial grooves formed in the sealing faces of either the rotor or the stator.
