Abstract: A material metering device and method for repetitively charging consistently accurate quantity charges of a lubricant retaining and wicking material to lubricant reservoirs of dynamoelectric machine bearings. A metering head is movably supported on a base for motion toward and away from a bearing and its support while both are held in alignment with the metering head. The metering head includes a dispensing chamber which may be sealingly coupled to the bearing support structure. The chamber receives lubricant retaining material from a source with excess material returning to the source. A valving arrangement interrupts the supply of material without substantially changing either the volume or pressure of the material in the dispensing chamber. An evacuation passage material flow path from the chamber to the bearing support structure or other workpiece is established and the material is extruded from the chamber.
