Title: Innovations of John J Vicari
Introduction
John J Vicari is a notable inventor based in Rockford, IL (US). He has made significant contributions to the field of fluid systems and control mechanisms. With a total of 3 patents, his work showcases innovative solutions that enhance the efficiency and precision of fluid flow systems.
Latest Patents
One of his latest patents is the "Fluid flow self calibration scheme." This invention involves a fluid system designed to calibrate a variable area metering valve during flight when the fluid receiver is not operational. It utilizes several single point fixed calibration orifices to establish multiple calibration points in a short time interval. The position of the metering valve's movable element is stored in a microprocessor's memory for each calibration point, allowing for precise control of flow rates without the need for a flow meter. This system effectively mitigates bench calibration inaccuracies and potential drift due to mechanical wear.
Another significant patent is the "Power drive unit and control system therefor." This invention addresses performance degradation in the control of variable displacement hydraulic motors. By measuring the angle of a displacement-setting wobbler and the motor's speed, the system avoids performance issues. It senses flow through the motor, providing an indirect measure of wobbler position and motor operation speed. The control system responds to a speed command based on a position loop, ensuring maximum possible motor speed under varying load conditions while maintaining a constant fluid flow rate.
