WORKING VALVE FOB, OIL-WELL PUMPS.-
Application filed August 9, 1921. Serial No. 490,827.
' and resident of Bolivar, county of Allegany,
and State of New York, have invented certain new and useful Improvements in Working Valves for Oil-Well Pump-s, of which the following is a specification. 1
This inventionv relates broadly to pumps for oil and artesian wells, and more particularly to a check valve and valve cage for the plungers or working valves of such pumps.
The primary object of the invention is to provide a working valve of a type commonly employed in oil wells, having a construction designed to insure the 'reseating of'the usual ball-check valve after each suction stroke, thus preventing the chattering which iseommonly produced by gas rising under pressure through the working valve and which frequently interferes seriously with the proper working of oil well pumps.
With this and other objects in view, the invention resides in the features of construe tion and arrangement of parts which will hereinafter be fully described, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of the upper portion of a working valve of an ordinary I type, showing my invention applied therel i re 2 is a longitudinal section on line 2-2,g l ig. 1; and
Figure 3 is a transverse section online 7 3'3, Fig. 1.
Referring to said drawings, 1 indicates the upper end portion of the hollow body of a plunger or working valve of a type more or less commonly employed in oil-well pumps, the same carrying the usual leather cups 2. Threaded within the upper end of said working-valve body is a short thimble 3 having its upper end shapedjoiorm a seat 3 for a ball-check valve 4.
Threaded exteriorly upon the upper end of the working-valve body is the lower end of a cylindrical cage 5 provided with one or more side openings 6, preferably two, three,
or four, for the outward passage of fluid which passes the valve 4 in the down stroke of the tool. Said cage has anintegral reduced stem 7 adapted for coupling to a sucker rod, and provided within said stem is a socket 8 designed for the reception of a light spiral spring 9 whereby said valve 4 is normally maintained. seated under yielding tension. An inverted cup 10, which loosely seats upon said valve 4, has'an upright stem 11 embraced by the lower end portion of said spring 9.
In practice, the valve t is lifted in the usual manner on each suction stroke of the tool, permitting the fluid to pass thereby to the interior of the cage 5, whence it passes outward through the openings or ports 6. Free passage of such fluid in an upward direction is permitted by the provision in thecylindrical wall of said cage of external vertical channels 12 which lead upward from each of said ports to the lower end of the reduced stem 7, as shown. Promptly following such suction stroke the spring 9 actuates the valve 4. to'return to its seated position. I
The spring is made of such tension that, while it permits unseating of the valve in the suction stroke, it will resist the pressure of gas in the well which tends tounseat the valve following such stroke. Thus, chattering of said valve due to the presence of gas is effectually prevented, and the gas. is consequently required to pass upward outside the well casing.
It is to be understood that the valve and cage structure described is not limited to any particular style or type of pump, but is readily applicable to practically any of the types employing ball-checks. Further, the
stem may have any desired formof end joint for coupling to the pump or sucker rod or line.
What is claimed isv 1. In a pump for oil wells, a working valve comprising a plunger body having a valve seat at its upper end, a cage threaded exteriorly upon said upper end, said'cage having longitudinal channels in its outersurface and having ports ppening into said channels, a ball-check valve enclosed by said cage and movable into and out of seating relation to said seat, an inverted cup resting on said valve and having an upright stem,
pumping apparatus comprising the combi nation with a tubular pump-casing presentlng a valve seat, a valve cage above the seat go; eee oe and a spring cket above the valve cage, its lower end pressed against the letter at 10 of-a ball within the said cage, a cap-piece the base of the stem.
engaging the said ball and having an -up- In testimony whereof, I aflix my signature wargly projectingfstlembafiapted on the upd-1 in presence of two subscribing Witnesses.
