Disclosed is a standing valve containing a ball, in which during operation, the ball is moved by ball guides to a position off center and yet not impinged against the valve, and in which unequal fluid flow areas are created around the horizontal circumference of the ball. Further disclosed are pumps utilizing such a standing valve.
Ball And Seat Valve Assembly And Downhole Pump Utilizing The Valve Assembly
Disclosed is a system used to increase the wear life of ball and seat valves and of ball and seat valves utilizing a piston mechanism to unseat the ball from the seat, which during operation, create turbulent flow within the valve preventing sand and other wear causing debris from collecting on and prematurely wearing pump components. Also disclosed is a wear and alignment bushing for ball and seat valves utilizing a piston to unseat the ball which reduces stress on the piston actuator.
Pump Barrel Seal Assembly Including Seal/Actuator Element
Disclosed is an assembly for unseating a seated traveling valve ball, and pumps utilizing such an assembly. The assembly generally includes a tubular member having therein a piston with an actuator for engaging the ball. Mechanical advantage is provided either by providing a sealing area of the piston that is greater than the sealing area of the seat valve and/or by providing a engaging member suitable to strike to seated ball asymetrically with respect to the vertical axis through the center line of the ball.
