Abstract
A lubrication nozzle has a body with a piston cavity formed therein. One end of the cavity is closed by an adjusting cap attached to a spring biased piston. The opposite end of the piston cavity has an orifice closed by a conical tip on the piston. Lubricating fluid and compressed air are supplied to separate ports in the body. The compressed air actuates the piston to open the orifice and permit the lubricating fluid to flow through a nozzle cap to an area to be lubricated. The tip and the seals on the piston are formed of an elastomeric material and easily can be replaced by removing the adjusting cap.
