Abstract
A lubrication system is disclosed for a bearing assembly, the bearing assembly having at least one bearing. The lubrication system may comprise a pump circuit, an injection circuit, an extraction circuit and at least one three-way valve. The pump circuit may comprise at least a pump. The injection circuit may provide lubricant to the bearing during an injection mode of operation. The extraction circuit may extract lubricant from the bearing during an extraction mode of operation. A flow combination topology of the first three-way valve may allow operation of the lubrication system in the injection mode or in the extraction mode or in both modes simultaneously.
