In order to effect a seal; a porous material which comprises one side of two opposing surfaces is used to restrict and evenly distribute externally pressurized gas, liquid, steam, etc. between the two surfaces, exerting a force which is opposite the forces from pressure differences or springs trying to close the two faces together and so may create a non contact seal that is more stable and reliable than hydrodynamic seals currently in use.
1. An aerostatic or hydrostatic bearing seal assembly comprising: a rotatable shaft with a runner coupled to the rotatable shaft;a housing located concentric to the shaft and defining a cavity;an annular seal body coupled to the housing;a primary ring coupled to the annular seal, the primary ring including a porous media positioned over a plenum and a port connected to the plenum,the seal body includes a conductive passage for communicating pressurized fluid to the plenum through the port of the primary ring,the plenum and the porous media distributes th...
