Abstract

Abstract ABSTRACT OF THE DISCLOSURE A single tube surface operated pump is provided herein, including a piston reciprocally mounted in a cylinder for alternate-ly 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 move toward the pumping mechanism is a spiral-like motion against the inner wall of the metallic tube and are reflected off of 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. Thus, by broad aspects of this invention, the sound pressure wave is generated by the impact of the end face of the aforesaid piston having the specially shaped recess or depression therein with the liquid. Such generated pressure wave; is used to move a column of liquid upwardly to the ground surface from an underground level.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 141 words
a lower cylinder having its upper end connected to said tube and having a lower end wall formed with a passage communi-cating with liquid in said lower level, 11. a one-way check valve in said passage, 111. a lower reciprocal in said lower cy-linder and including a head and tubular main body portion providing a passage extending through said plunger, IV. an internal rib on said lower cylinder, and V. an expansion coil spring interposed between said rib and said plunger head and exerting a force to accurately counter-balance the weight of a column of liquid in said tube; said plunger head having a flat upper surface for reflecting sound pressure waves coming downwardly along the inner sur-face of said tube inwardly and upwardly to move liquid upwardly through said tube and through said lateral port when the latter is open.
Claim 2
Dependent Claim 141 words
a lower cylinder having its upper end connected to said tube and having a lower end wall formed with a passage communi-cating with liquid in said lower level, 11. a one-way check valve in said passage, 111. a lower reciprocal in said lower cy-linder and including a head and tubular main body portion providing a passage extending through said plunger, IV. an internal rib on said lower cylinder, and V. an expansion coil spring interposed between said rib and said plunger head and exerting a force to accurately counter-balance the weight of a column of liquid in said tube; said plunger head having a flat upper surface for reflecting sound pressure waves coming downwardly along the inner sur-face of said tube inwardly and upwardly to move liquid upwardly through said tube and through said lateral port when the latter is open.
Claim 3
Dependent Claim 54 words
The sound wave surface operated single tube pump of Claim 1 in which the recess in the end face of the piston is defined by a flat angular ring-like surface, a truncated conical surface opening onto said ring-like surface and a cylindrical end socket communicating with the small end of said truncated conical surface.
Claim 4
Dependent Claim 19 words
The sound wave surface operated single tube pump of Claim 2 in which the metallic tube is of steel.
Claim 5
Dependent Claim 32 words
The sound wave surface operated single tube pump of Claim 1 in which the lower cylinder is integrally joined with the lower end of the metallic tube by a trun-cated conical wall.
Claim 6
Dependent Claim 44 words
The sound wave surface operated single tube pump of Claim 1 in which the power means for reciprocating the piston includes a fly wheel, a crank arm connected to the fly wheel and a piston rod connected to the crank arm and said piston.
Claim 7
Dependent Claim 24 words
The sound wave surface operated single tune pump of Claim 1 in combination with a bleed valve at the lower end of the plunger.
Claim 8
Dependent Claim 38 words
The sound wave surface operated single tube pump of Claim 1 in which there are one or more aligned one-way check valves at the lower end of the cylinder and which communicate with liquid in said lower level.
