Abstract
A hydraulic lifter of automatic regime, characterized by being installed in a hydraulic impeller pump, installed in a support frame that comprises and immobilizes a cylindrical container from which a closed cylinder is derived centrally and inferiorly constituting itself in the true pump body, inside which a solid plunger column slides as a central appendage of another cylindrical body, in turn bare and free, of ascending movement, suitably guided by clamps in the component peripheral columns of the support tower to constitute the head of the piston cited with the particularity that the passage of water from the container body to the lower area of the pump, is verified by a collateral conduit that connects both elements, counting in its interior with a regulating valve of passage in one direction while the exit of said pump body occurs at the junction of a raised point thereof, of another second lifting duct, properly oriented and equipped likewise with the corresponding pneumatic valve.
