Abstract
There is provided an improved fluid pumping device including an enclosure to be placed downhole in a well. A first hollow tube is received in the enclosure and extends to the surface of the well for removing fluid from the well. A second hollow tube also extends into the enclosure for forcing a gas into the enclosure. The bottom of the enclosure has an opening for permitting fluid to enter. A mechanical mechanism is provided for forcing the closing of the opening in the enclosure so that the device may be utilized in deep wells where high fluid pressures occur.
