  • Patent number: 12078039
    Abstract: An actuator to operate a plunger catcher to capture and release a plunger used in a plunger-assisted artificial lift system. A case is connectable to a lubricator on a wellhead and a motor drives a rotary shaft. A plunger sensor is disposed proximal to the lubricator and connected to a distal end of a plunger rod. A proximal end of the plunger rod extends into the case and is coupled to the rotary shaft. A source of current connects to the motor. A processor/controller controls operation of the motor, and a plunger sensor detects the presence of the plunger within the lubricator. The actuator may be operated to capture the plunger within the lubricator by extending the plunger rod outwardly from the case, and later to retract the plunger rod inwardly to release the plunger.

  • Patent number: 9212760
    Abstract: A rotary actuator (10) rotates a drive shaft (40), which in turn rotates a stem (76) between an actuator housing (32) and a central body (48). Drive pins (50, 52) extend between the central body of a rotary sleeve (42), and move within helical guide slots (80, 82) to linearly raise and lower the central body (48), which is connected to the linear controller (18).
