Abstract
A system and method are disclosed for protecting bearings operating in dirty environments. The system may include a reservoir of lubricant, a bearing, and a regulator. The bearing may border on both the dirty environment and the reservoir. Accordingly, the bearing may be exposed to the solid particles carried by the fluid within the environment, as well as the lubricant of the reservoir. The regulator may ensure that the pressure within the reservoir is greater than the pressure of the dirty environment. Due to the higher pressure within the reservoir, the bearing may be preferentially filled with lubricant rather than dirty fluid from the environment.
