Title: David L Fuelberth: Innovator in Hydraulic Systems

Introduction

David L Fuelberth is an accomplished inventor based in Dunlap, IL (US). He has made significant contributions to the field of hydraulic systems, holding a total of 2 patents. His innovative designs focus on improving the efficiency and reliability of hydraulic devices.

Latest Patents

One of his latest patents is the "Fluid Leak Limiter," which is designed for high-pressure fuel injection systems. This fluid leak limiter features a body that partially defines a central bore, equipped with a fluid inlet and outlet. A piston is reciprocatingly disposed within the central bore, and a spring biases the piston toward a first flow-blocking position, preventing fluid from flowing from the inlet to the outlet. Additionally, the device includes a pin that can selectively lock the piston in a second flow-blocking position.

Another notable patent is the "Method and System to Monitor and Control the Activation Stage in a Hydraulically Actuated Device." This method involves adjusting the performance of an electronically controlled hydraulic system. It begins with providing an electronically controlled hydraulic device that has a control valve member coupled to an electronic actuator. The device is activated according to a specific activation profile, and the impacts of the control valve member on a seat are detected and recorded. The characteristics of these impacts are then compared to expected values, allowing for adjustments to the activation profile if necessary.
