The upper poration of the method features in the disclosure tion of the pump housing is snugly intruded into and from an inspection of the accompanying the lower end of the outer pipe 29 and fastened drawing and in part will be more fully set forth thereto by a driven fit or by other approved in the following particular description of one means. The inner pipe 30 is of materially remethod of practicing the invention, and the induced cross" sectional area compared to the cross vention also consists in certain new and novel section of the outer pipe 29, and has its lower modifications of the preferred method and other end intruded into the upper end of the cylinder features of construction and combination of I 5 and abuts against the annular shoulder 3| parts hereinafter set forth and claimed. formed by the stop ring H.

In the accompanying drawing the figure is a The inner pipe 3|! is filled with some suitable fluid 32 capable of emciently transmitting the wave impulses of sonic frequency, and it is, herein sug ested that a light form of oil has proven satisfactory in situations such as is herein contemplated. The column of oil in the inner pipe also fills the portion or the chamber above the oscillator 20 so that there is a solid column of oil between the top surface 33 of the oscillator and the plunger 34 of a sonic vibrator 35. This vibrator is of any conventional form and the showing herein is simply symbolic.

The bores l4 and i 6 and the oscillator 20 and its stem 2! have suillcient length dimensions so as to defeat possibility of the oil in the column 32 flowing past the oscillator into the pressure chamber-23. As some oil-creep between the oscillator 20 and the walls of the guideway l9, the oscillator is lubricated and thus is free to be responsive to the high speed vibratory action herein featured. However, in order to insure nonleakage between the oil column and the column of fluid being pumped through the pipe 29 in all operative positions oi the oscillator a Syiphon bellows 36 telescopes a boss 31 depending from the spider l2 and also telescopes a boss 38 formed on the upper side of the pump piston. An intake screen or well casing 39 is shown with the lower portion of the pump housing I intruded into the same.

In operation, and assuming that the pump has been primed at least to the extent of there being shown in the drawing, the device is then ready-- for action. The sonic vibrator 35 is set in motion and an impulse is sent downwardly through the oil column 32 to lower the piston 22. A small portion of the fluid to be elevated is caused to enter the intake ports 24, pass the alternately opening and closing valves 26, the fluid so admitted passes through the pressure chamber 23, and upwardly through the ports I3 and through the annular space formed between the inner and outer pipes to the point of discharge at the earths surface, or elsewhere.

Described more in detail, it will be understood that on the initial downstroke of the vibrator plunger 34, a wave of condensation will be sent downwardly through the oil column 32 with the result that the oscillator is moved downwardly 'from its initial position. The downward movement of the oscillator will similarly lower the pump piston 22 into the body of fluid therebelow within the casing 39. This fluid reacts on the seated valves 26 to move them from their seated position into their elevated open position shown in the drawing. This movement causes some of the fluid below the piston to by-pass the valves and move into the pressure chamber. On the succeeding upward movement of the sonic vibrator piston, a wave of rarefaetion will be created in the oil column which will react on the oscillator to elevate the same slightly from the position shown in the drawing. This elevating movement will cause the pump piston to be similarly elevated, and this, in turn, will cause the fluid in the compression chamber 23 to react on the valves 26 and thus to move them'back into their initial seated position, thus intercepting the possibility of the liquid in the pressure chamber from retreating downwardly back through the inlet ports 24. This liquid in the pressure chamber is elevated by the raising of the pump piston, thus forcing a Portion of the liquid in the pressure 4 chamber upwardly through the ports [3 and into the fluid conduit as indicated by the long arrows.

It will be understood that this alternateraising and lowering otthe pump piston with its associated opening and closing or the valves will be repeated with each change of direction of the sonic vibrator piston.

By means of a device or this character, it is possible to effect an economic actuation oi. the sonic pump without loss of the actuating liquid in the oil column, and as this oil column is contained within the conduit for the pumped liquid, the whole device may be contained in a single well casing in the event that the device is used in well pumping. The disclosure features simplicity of parts, particularly in the movable parts which in efiect have been reduced to a single unit and which unit may be readily replaced, when worn, with a new unit.
