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.
Claims19
A lubrication system for a bearing assembly, the bearing assembly having at least one bearing, comprising:
- a pump circuit, having at least a pump;
- a lubricant injection circuit for providing lubricant to the bearing during an injection mode of operation;
- a lubricant extraction circuit for extracting used lubricant from the bearing during an extraction mode of operation;
- and
- at least a first three-way valve, having a first port coupled to the pump circuit, a second port coupled to the lubricant injection circuit and a third port coupled to the lubricant extraction circuit,
- wherein the first three-way valve allows operation of the lubrication system in the injection mode or in the extraction mode or in both modes simultaneously.
