Abstract
An injection lubricator including a lubricant pump having a pumping piston actuated by a pneumatic pulse to deliver a pulse of lubricant to a lubricant pump outlet, a lubricant distributor having a lubricant distribution inlet in communication with the lubricant pump outlet, a plurality of lubricant distribution outlets, and switchable flow paths within the distributor to cause one lubricant distribution outlet to be connected to the lubricant distribution inlet at one time, and a pneumatically-actuated piston that advances the lubricant distributor to switch to a different lubrication outlet with the application of each pneumatic pulse.
