ABSTRACT:
Apparatus for lubricating pistons having a pressure metered lubrication reservoir in fluid flow attachment with the piston through a lantern port in the wall of the stuffing box surrounding the piston. A check valve in fluid flow alignment between the stuffing box and the lubrication reservoir prevents the flow of spent hydraulic fluid from the stuffing box into the lubrication reservoir in the event of a seal leak or failure. A safety valve having a higher trigger pressure than the pressure of the lubricant flowing from the reservoir to the stuffing box and being in fluid flow alignment with the stuffing box and lubrication reservoir prevents the escape of lubricant flowing from the reservoir to the stuffing box, but allows the escape of spent hydraulic fluid in the event of a seal leak or failure.
