Abstract:
The Invention provided is a hydraulic powered down hole reciprocating pump traveling valve component to provided lifting hydraulics on the down stroke using the derived motion and pressure of petroleum liquids and gasses, such as oil, water and natural gas and also utilizing the frictional traveling forces driven by the surface equipment. Designed to utilize the elements within the pumping apparatus to obtain the hydraulic power within and transfer the energy's force to the exposed bottom end of the pressure locked traveling ball valve adjacent within the ball valve containment cage, providing ultimate lifting power to open the ball valve on the initiation of the down stroke. The component consist of a Hollow Hydraulic Power Shaft, Hollow Pressure Motion House, and a Fluid Cavity Power Drag Plunger.
