Abstract
A lubrication system for supplying lubricant to a plurality of antifriction bearings, and which has a lubricant supply tank and a closed circuit lubricant supply line having two ends which communicate with the tank. A pump circulates the lubricant through the line, and a pressure regulating valve in the downstream end portion of the line maintains a desired pressure in the line. A plurality of tap lines lead from the closed circuit supply line to respective bearings via a metering or controllable valve.
