ABSTRACT:
A single tube surface operated pump including a piston reciprocally mounted in a cylinder for alternately opening and closing a lateral fluid delivery port and for generating a sonic pressure wave by impacting a column of fluid in a metallic tube extending from the cylinder to a remote pumping mechanism located in communication with the fluid to be pumped. The piston is especially configured with a central recess in the face thereof so that the sonic pressure waves generated thereby will pass through a sonic nozzle and move downwardly toward the pumping mechanism in a spiral-like motion against the inner wall of the metallic tube and enter into a sonic intensifier chamber and are reflected off the pumping mechanism into a central column which travels back toward the cylinder and causes the fluid to be pumped to move in that same direction.
