ABSTRACT:
Gas bearing of the hydrodynamic self-acting type in which replenishment gas for the support film is drawn by the operating bearing through filter means as required to assure entrapment of potentially damaging particles before they can enter the gas film in the narrow clearance between the rotating and stationary bearing members. To further increase the flow of filtered gas, the bearing elements may optionally be equipped with supplemental gas pumping apparatus.
