Abstract: A non-contact air bearing having electrostatic discharge properties may comprise: a porous media element having a bearing surface; a supply line configured supply an externally pressurize gas or fluid to the porous media; and an electrostatic dissipative porous bearing layer on the bearing surface of the porous media element; wherein the externally pressurized fluid flows through the porous media element and creates a thin film between the electrostatic dissipative layer and a substrate supported by the air bearing.

Abstract: An externally pressurized porous gas bearing for operating within a refrigerant environment is disclosed. The gas bearing utilizes shear heating from rotation of a rotor, thereby increasing the pressure and load capacity of the externally pressurized porous gas bearing. The gas bearing is capable of operating when the refrigerant is in a liquid phase and when the refrigerant is in a gaseous phase.

Abstract: 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. A non-contact bearing is also disclosed having opposing surfaces with relative motion and one surface issuing higher than ambient pressure through a porous restriction, wherein the porous restriction is part of a monolithic porous body, or a porous layer, attached to lands containing a labyrinth, the porous restriction and lands configured to not distort more than 10% of a gap created from differential pressure between each side of the porous restriction.

Abstract: A gas bearing assembly includes a snap joint for attaching an externally pressurized porous gas bearing to a bearing cartridge. The gas bearing assembly has an adjustment screw which supplies a gas to an end of the adjustment screw via a through bore. The externally pressurized porous gas bearing has a housing portion with a washer and a snap ring. The gas bearing assembly additionally includes an air transfer tube positioned in the end of the adjustment screw and the housing portion. The washer and the snap ring retain the housing portion on the end of the adjustment screw to removably retain the bearing on the bearing cartridge.

Abstract: In order to drastically improve the functionality of flow control, externally-pressurized porous media gas bearings is introduced into valves. The porous media gas bearings mitigate two of the biggest issues with the current technology, which are: (1) leakage of fugitive emissions, and (2) high breakaway torque values for actuating valves. By employing externally-pressurized porous media bearings, fugitive emissions are completely eliminated, and valves can be rotated effortlessly due to the non-contact nature of porous media gas bearings.
