Title: The Innovative Contributions of Craig Grant Haroldsen
Introduction
Craig Grant Haroldsen is a notable inventor based in Orem, Utah. He has made significant contributions to the field of valve actuation systems, showcasing his expertise and innovative spirit. His work has led to the development of a unique patent that enhances the efficiency of hydraulic systems.
Latest Patents
Haroldsen holds a patent for an "Air over hydraulics actuator system." This valve actuation system integrates pneumatic and hydraulic control features. The system generates compressed pneumatic fluid in a supply, which flows based on the requirements between a command signal and the existing position of a working fluid valve. Additionally, hydraulic fluid is pressurized by a pump and stored within the system by an accumulator. A servo valve is included to facilitate the flow of hydraulic fluid through its hydraulic path and a downstream actuator for the working fluid valve. This flow is proportional to changes in pneumatic fluid flow through the servo valve's pneumatic path. Furthermore, a saturated fluid feedback circuit is incorporated to shut off the flow of both pneumatic and hydraulic fluid during specific periods, typically coinciding with static conditions within the actuator, thereby reducing the pump's duty cycle.
