摘要： An automatic gas operated downhole fluid pump having an elongated cylindrical chamber for receiving fluid and having a concentrically mounted cylindrical float which is connected to a valve having an actuator biased and retained in either an opened or closed position with an elongated control rod connected with the valve actuator and extending through a passageway through the cylindrical float with adjustable means to adjustably connect the control rod with the cylindrical float to apply force to the actuator only when it is desired to actuate the valve.

摘要： A generally elongated cylindrical pump adapted to be lowered into a fluid producing formation comprising a hollow annular outer chamber circumferentially about a hollow cylindrical inner chamber, a valve mounted in said inner chamber, a source of compressed gas adapted to be applied to said valve, a float reciprocally mounted in said inner chamber coacting with said valve to apply said compressed gas to said inner chamber when said float is raised to a predetermined height and the fluid is then forced through said outer chamber to an outlet bore; the compressed gas applied to said inner chamber is cut off when such pumping operation is completed.
