OIL-WELL PUMP.
Application filed April 17, 1928. Serial No. 270,744. D
This invention relates to oil well pumps and more particularly to that type of pump wherein the oil is lifted from the well by use of compressed air or gas or a mixture thereof. y An important object of this invention 1s V the improvement of the structure shown in my prior application, No. 244,495, filed January 4, 1928, for oil well p umps, to permit elimination of certain of the elements employed in the structure described in said application while preserving the operative features thereof.
A further object of the invention is to provide a device of this character having means whereby the amount of air which is admitted as well as the pressure of such air may be controlled.
A still further object of the invention is to provide a novel and improved packing and guide element for use in such devices.
A still further object of the invention is to provide a nozzle element formed in two sections, one of which is movable andoperyates as a valve controlling the admission of the air or gas employed to lift thev fluid from the well. y
These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a vertical sectional view through one of the nozzles of a pump constructed in accordance with my invention; Figure 2 is'ia Vsection on the line 2-2 of Figure 1.
Referring now more particularly to the drawings, the numeral 10 generally designates aiit-ting having a bore 11. Within this bore at the lower end thereof is disposed a check valve organization, generally designated at 12. The upper end of the bore is interiorly threaded, as at 18, for the reception of the lower end of the tube 14 and which, as illustrated, is preferably formed in sections. The lower end of the body is eX- teriorly threaded for engagement with tubrannular groove 17 which communicates with vertically extending ports 18 openingl 50 through the upper end of the fitting and between the tube 14 and the inner wall of the sleeve. The lower end of the sleeve has radially extending ports 19-which communicate with the groove 17.
At its lower end, the exterior of the sleeve Vhas rotatably mounted thereon a ring valve 20 having openings 21 which, by rotatably adjusting the ring, may be brought either into full register with the ports 19 of the 70 sleeve or disposed to render available any desired portion of these ports. This valve may be secured in adjusted positions by any f suitable means such as that indicated at 22.
The threaded portion 16 of the sleeve at 75 its lower endhas engaged therewith the exteriorly threaded flange 23 of a guideslrt 24, the outer faceof which is in spaced relation to the wall of the sleeve. This guide sleeve is held in'position by a lock nut 25 80 and the inner faces of both the skirt and nut are provided with annular grooves 25'i having horizontally extending upper walls and lower walls which incline inwardly and outwardly to meet said upper walls. s
Slidable within the skirt is a nozzle element 26, the walls of the upper end of which converge to a point where they closely approximate the outer face of the tube 14, as indicated at 27, and then extend in parallel im relation to this tube, so that a narrow annular space 28 isprovided through which as or air may pass. The lower end of t is nozzle is formed as a valve 29, seating upon the upper end of the fitting 10 and closing 9s the ports 18. A spring 30 surrounding the e device.
skirt 24 and engaging against the flange 23 of this skirt at its upper end and against the valve 29 at its lower end holds the valve seated until a predetermined pressure of the air or gas is built u The gas or air, when this pressure is attalned, forces the valve 29 and nozzle 26 upwardly against the action of the spring and then passes into the space 3l between the tube 14 and nozzle 26. In lts escape through the narrow annular passage 28 near the upper end of the tube, it is directed up along the walls of the nozzle.
In its passage beyond the end of the tube, it acts as an ejector, creating a vacuum within the tube 14 which lifts the oil. It also causes an intermingling of this oil with the air, so that the oil rises in the tube to a point where it may be picked up by a second nozzle.
In using the construction of my prior application, a plurality of the nozzles are inserted in the oil well tubing at points spaced apart a distance determined by the character of the fluid which is being handled and the pressure which is available.
It will be obvious that the sleeve 15 and tube 14 might be formed integrally with the fitting" 10, the present construction having been merely adopted as providing for more convenient construction and assembly of the The structure, as illustrated, may be very readily and cheaply manufactured and is of such character that it will not readily get out of adjustment.
.Since the construction hereinbefore set forth is ca able of a certain range of change and modi cation without materially departing from the spirit of the invention, I do not limit myself to such specilicstructure except as hereinafter claimed.
I claim 1. A nozzle for oil wellA pum s comprising a body having a bore, a tu e threaded in the upper end of the bore, a nozzle element surrounding the tube, ports for admitting air between the nozzle element and the tube, the lower end of the nozzle element comprisin a valve for sealing said ports, and a spring for seating said valve.
