TRAVELING OIL PUMP VALVE ABSTRACT OF THE DISCLOSURE A conventional pumping unit is mounted at ground level, to which is attached a hollow sucker rod that extends through a tubing string to the production level of the well. Integral with the tubing string is pro- vided a pump barrel, with communication between the production formation and the tubing string being effected across a ball and seat check valve. Secured to the lower extremity of the hollow sucker rod is an elongated sleeve-like pump housing having a sealing element at the lower extremity thereof establishing a seal between the pump housing and the pump barrel. Intermediate the extremities of the hollow pump body is formed a plurality of elongated slot-like ports extending parallel with the longitudinal axis of the pump body. An elongated traveling piston is located for reciprocal move- ment within the pump body and is also provided with a seal at the lower extremity thereof for establishing a sealed relationship with the pump barrel. Ports are formed in the tubular wall structure of the traveling piston to enable pressure induced transfer of well fluid from the pump barrel into the tubing string. The ports of the traveling piston and pump body are capable of registering upon predetermined positioning of the traveling piston relative to the pump body. Such positioning is estab- lished upon predetermined movement of the traveling piston relative to the pump body in opposition to the force of a compression spring. A piston valve seal sur- rounding a portion of the traveling piston is movable to an open position as the traveling piston moves against the compression of the spring, thereby facilitating flow of a fluid through the valving mechanism past the sealing elements to enable it to be forced upwardly as the pump mechanism is moved upwardly through movement of the sucker rod. The pump mechanism will allow well fluid to be con- tinuously pumped and will effectively prevent the develop- ment of a gas-lock condition during pumping. An alterna- tive embodiment of the present invention may be utilized in conjunction with a solid sucker rod, with the variable volume compression spring chamber between the pump body and traveling piston being vented to the tubing above the seal between the pump housing and the pump barrel. -2-
