摘要： A lubrication system for a tool powered by a drive fluid is provided. The lubrication system includes a reservoir configured to deliver a lubricant and a plunger disposed within the reservoir. The plunger is configured to selectively generate a pilot signal based on a level of the lubricant. The lubrication system further includes a valve having a housing. The housing includes a drive fluid inlet and a drive fluid outlet. The valve also includes a pilot spool configured to move from a neutral position to an actuated position in response to the pilot signal. The valve further includes a main spool selectively actuated by a pressure of the drive fluid to move from a first position to a second position in response to the movement of the pilot spool such that in the second position the drive fluid inlet is in fluid communication with the drive fluid outlet.
