Latest Patents

Barrus's latest patents include the "High Pressure Automatic Mud Saver Valve" and the "High Pressure Automatic Kelly Valve." The High Pressure Automatic Mud Saver Valve is an innovative diaphragm-type mud saver valve, commonly referred to as a Kelley valve, designed to close automatically to prevent the loss and spilling of drilling mud. This improved valve can endure very high drilling and pump pulsation pressures, suitable for drilling wells over 20,000 feet deep, where mud pressures can exceed 15,000 p.s.i. The design expertly prevents the formation of gas pockets by incorporating gas escape openings and a clearance space between support and backup elements, thus prolonging the lifespan of the diaphragm and ensuring proper seating.

His other patent, the High Pressure Automatic Kelly Valve, allows for the automatic closure of the valve, minimizing the risk of loss and spilling of drilling mud during operations in high-pressure wells. This valve integrates a diaphragm, rigid backup means, and diaphragm support means to enhance performance in demanding environments.
