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.

1-29. (canceled)
A method for automatically adjusting an output of a lubricator pump having a piston housed in a pump body, the method comprising:
- operatively connecting an actuator to a piston housed in the pump body;
- monitoring an output of the lubricator pump;
- and
- activating the actuator in response to changes in the output of the lubricator pump wherein the actuator automatically causes an adjustment to a stroke of the piston such that a flow of lubrication out of the output of lubricator pump at least one of increases or decreases.
A method for automatically adjusting an output of a lubricator pump, the method comprising:
- establishing a threshold lubrication rate;
- monitoring, with a sensor, an actual lubrication rate at the output of the lubricator pump;
- determining whether the actual lubrication rate is above or below the threshold lubrication rate based on the comparison;
- causing the lubricator pump to decrease a lubricator pump output when the actual lubrication rate is determined to be above the threshold lubrication rate;
- causing the lubricator pump to increase the lubricator pump output when the actual lubrication rate is determined to be below the threshold lubrication rate;
- and
- maintaining the lubricator pump output when the actual lubrication rate is not above or below the threshold lubrication rate.
