Patent attributes
Methods and systems are shown lubricating a cylindrical bore. In one example, a lubrication system comprises a piston-shaped bore lubricator with a plunger portion including a soft, porous material arranged in an external groove at a distal end of the plunger portion, the groove including holes through which a lubricant is ejected into the soft, porous material as the plunger portion is positioned in a bore. A proximal end of the piston-shaped plunger includes threads for coupling a squeezable lubricant source bottle, where the lubricant is ejected through the felt via an actuation of the squeezable bottle, or by gravity, or via a different kind of dispenser. An outside diameter of the piston may be adjusted to fit an interior diameter of the bore, and a size of the holes may be adjusted to increase or decrease a flow rate of the lubricant.
