Abstract
An annular lubrication reservoir is mounted on the periphery of a rotatable shaft, the reservoir defining a fluid tight annular enclosure having one or more apertures through its outermost surface. Conduit means are connected to the aperture for conducting lubrication from the reservoir to a bearing surface. Valve means are mounted in the aperture to limit the lubricant flow to one direction, out of the reservoir toward the bearing surface. A piston pump is mounted in association with the apertures whereby on rotation of the shaft the piston is driven radially outward to force lubricant out of the reservoir through the valve and into the conduit.
