Abstract
A lubricator pump adjuster for use with a lubricator pump having a piston housed in a pump body and a rocker connected to the piston. The lubricator pump adjuster comprises a mounting fitting attachable to the pump body and a housing disposed on the mounting fitting. An actuator is disposed in the housing and connectable to the rocker, whereby activation of the actuator causes the rocker to move, thereby adjusting the stroke of the piston. The actuator is a rotary actuator with an output shaft. The lubricator pump adjuster includes a cam faced member attached to the output shaft, and a plunger in contact with the cam faced member that is connectable to the rocker. The cam faced member may include a spiral-ramped surface.
