ABSTRACT:
A system for supplying lubricant under pressure to a rotary mounting system having bearings when the main pressurized lubricant supply system fails. The system includes a bladder or other expansible chamber in association with a lubricant reservoir. The bladder has a source of pressurized gas which is either inherently or through regulation maintained at a pressure below that of the main system and above that of the lubricant discharge from the bearings. The source of pressure for the reserve system may be pressure from a gas seal or from the rotor chamber of a pump or turbine. If regulated, the regulation may be by the main lubricant pressure or the pressure of the lubricant discharge. The system also contemplates accommodation for leaks and over pressures.
