ABSTRACT:
A well system includes a free lift plunger, and a gas supply line and associated motor valve for supplying intermittently injection gas to effect the lifting of the plunger and a slug of production liquid to the outflow line. The motor valve is diaphragm operated; and a control for this motor valve includes a known type of mechanical timer and associated valve which alternately pressurizes and vents its outlet line to alternately effect the closing and opening of the motor valve. An auxiliary control for this system includes a pilot valve and magnetic actuator which responds to the arrival of the lift plunger at the delivery point to effect the closing of the motor valve. A magnet, pivotally mounted on a lever, maintains the pilot valve closure member in a normal first condition, and is shifted by the arrival of the magnetic plunger to shift the valve closure member to a second condition to effect the closing of the motor valve.
