Abstract

A bearing lubrication system for turbine apparatus. Lubricating fluid stored in a pressurized oil reservoir is pumped by a main oil pump to the bearings. An oil cooler is provided immediately upstream of the pressurized reservoir to lower the temperature of the fluid stored therein and provided to the bearings. Oil returned from the bearings is drained to a nonpressurized oil collection chamber which supplies the suction of the main oil pump. An emergency gas system is included to insure an independent oil flow capacity in the event of interruption in power to, or failure of, the main oil pump.
