With a remarkable portfolio of 7 patents, Smith's work embodies a blend of creativity and technical expertise that addresses practical challenges in various industries.

Latest Patents

Among his latest inventions is the **Pressure Latched Poppet Cartridge Valve**, a sophisticated pulse piloted cartridge valve that reliably defaults to a closed position. This valve utilizes a spring that biases against a latching piston assembly to seal the supply port from the control port in its closed state. The mechanism allows pressurized fluid to be directed in a pilot open chamber, enabling the pilot open piston to maneuver the latching piston assembly to an open position. When open, it establishes passageways between the control and supply ports. The system's design ensures that once opened, the latching piston can remain in position even after the pilot pressure is removed. Additionally, the valve can be closed through a pilot closed chamber or by lowering pressure on the supply port.

Another significant patent is for **Adjustable Springs for Pressure Vessel Closure**. This innovative closure device effectively manages the lower opening of a coke drum pressure vessel. It features a quick-acting mechanism that involves an annular flange and movable support encircling the vessel. Hydraulic cylinders facilitate the axial movement of the movable support, enabling a head to tightly engage the flange upon release, while independently adjustable springs optimize the closure pressure.
