<p>A lubricated hydrostatic seal comprising (a) surface regions having opposing surfaces (11, 113); (b) a plurality of micropores in one or more of said surfaces having a pore geometry; and (c) a flow of fluid (116) between said surfaces, wherein said flow of fluid past said micropores provides a lifting force between said surfaces. In a preferred embodiment, the opposing surfaces of the surface regions are nominally parallel. Nominally-parallel surfaces are simple to manufacture and are considerably less expensive than the various converging-surface configurations of the prior art. The nominally-parallel surface configuration can also be utilized in both liquid-lubricated and gas-lubricated hydrodynamic seal applications, and in hybrid-seal applications in which both hydrodynamic and hydrostatic lift are generated.</p> |
