ABSTRACT:
An airline lubricator in which a diaphragm is disposed in a closed annular chamber surrounding an axial air passage to divide the chamber into an air pressure chamber and a lubricant reservoir. The air pressure chamber is coupled by an angulated pressure tube to the primary air passage adjacent the lubricator inlet. A metering tube and adjustable screw arrangement at the output of the reservoir control the amount of lubricant fed to the primary air passage as a function pressure drop across the primary air path. A ball-type check valve including an adjustable valve seat is disposed across the primary air path in opposition to the metering tube for preventing passage of lubricant in the absence of primary air flow.
