Abstract

A variable volume single tube surface operated pump including a piston reciprocally mounted in a cylinder for alternately opening and closing a liquid delivery port formed in the sidewall of the cylinder and for generating a sonic pressure wave by impacting a column of liquid in a metallic tube extending from the cylinder to a remote pumping mechanism located in communication with the liquid 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 inductor 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 where they are reflected off the pumping mechanism into a central column which travels back toward the cylinder and causes the liquid to be pumped to move in that same direction. A power operated drive mechanism is provided for reciprocally driving the piston and for adjustably varying the output volume of the liquid delivered by the pump.

Dependent claims

A variable volume sonic pressure wave surface operated single tube pump for pumping liquid from an underground level to a ground surface comprising:

(a) a sonic pressure wave generator including,
I. a cylinder housing having a bore for containing liquid in one end portion thereof and having a liquid delivery port means extending laterally from that bore,
II. a liquid impacting piston reciprocal in the bore of said cylinder housing for opening and closing the liquid delivery port means thereof and for reciprocally impacting the liquid containable therein,
III. said liquid impacting piston having a liquid impacting end face with a central recess formed therein which generates a sonic pressure wave upon impacting the liquid containable in the bore of said cylinder housing,
IV. a sonic inductor in the form of a sonic nozzle having a bore for containing liquid located in the one end portion of the bore of said cylinder housing so that the bore of said sonic nozzle is coaxial with the bore of said cylinder housing;
(b) a metallic tube having a bore for containing liquid and having one end which is in communication with the bore of said nozzle so that the sonic pressure waves generatable in said cylinder housing will pass through said sonic nozzle and be received and transmitted in the bore of said metallic tube;
(c) pumping mechanism means connected to the other end of said metallic tube and in communication with the liquid to be pumped, said pumping mechanism means including a reciprocally operable plunger for impingingly receiving the sonic pressure waves when transmitted by said metallic tube and reflecting those waves into a centrally and upwardly moving column which carries the liquid being pumped in the same direction;
(d) power input means;
and
(e) drive/output volume adjustment means connected to receive power from said power input means and coupled to said liquid impacting piston for reciprocal driving thereof, said drive/output volume adjustment means including means for adjustably varying the stroke of said liquid impacting piston for adjusting the output volume of the liquid being pumped.
