ABSTRACT:
A precision, highly reliable, positive displacement, pneumatic lubricant for pumping lubricant to a tool and work piece during machining operations; and for delivering compressed atomizing air thereto. The lubricator pumps lubricant substantially continuously at highly accurate, very low flow rates which can be minutely varied according to the needs of the user. The lubricator's piston delivers one pulse of lubricant for each input air pulse which is supplied to the lubricator from a source of input air pulses. The lubricator includes internal check valves for preventing back flow of lubricant into the lubricator's source, and for preventing back flow of pumped lubricant into the lubricator. The lubricator has an adjustable stop which controls the stroke of its piston, and which thus controls the amount of lubricant which is pumped by each pumping stroke of its piston. The lubricator also has positive stops for the maximum and minimum adjustment of its adjustable stop. The positive stops prevent endless turning of the lubricator's adjustable stop in either direction with no change being made in the amount of lubricant pumped by each pumping stroke of its piston. The lubricator's valve body is made stackable so that one lubricator may comprise several valve bodies; each valve body being able to independently deliver lubricant and atomizing air to its respective tool and work piece through coaxial atomizing air/lubricant output lines. If the lubricator has more than one valve body, their lubricant input means, air pulse input means, air relief means, and compressed air input means are in fluid communication with each other.
