Title: Mark S. Megill: Innovator in Hydraulic Control Systems
Introduction
Mark S. Megill is a notable inventor based in Tulsa, OK (US), recognized for his contributions to hydraulic control systems. With a total of 4 patents to his name, Megill has made significant advancements in the field, particularly in the design and functionality of downhole valves and pressure equalization systems.
Latest Patents
One of Megill's latest patents is the "Flapper Equalizer with Integral Spring." This innovative design features a flapper equalizer plunger that incorporates a unitary coiled spring. The spring is compressed by the flow tube, allowing the plunger to shift and equalize pressure across the flapper before the flow tube attempts to move it. This design simplifies the hydraulic control system, requiring only the force to overcome the flapper pivot spring to swing the flapper open. The integral spring is produced using a wire EDM technique and can be designed to be symmetrical or asymmetrical, which helps to offset off-center impacts from the flow tube.
Another significant patent is the "Multi-Stage Pressure Equalization Valve Assembly for Subterranean Valves." This downhole valve operates by turning a member with a passage through it, featuring a control system that includes a passage from above an uphole seat. This passage communicates with an isolated passage within the member when the valve is closed. The design includes a check valve assembly with redundant sealing features and filters to prevent debris entry. This innovative approach allows pressure applied from above the closed member to equalize the pressure below the ball, enhancing the valve's functionality.
