Title: The Innovations of Donald E. McGovern
Introduction
Donald E. McGovern is a notable inventor based in Dubuque, IA (US). He has made significant contributions to the field of hydraulic systems, holding a total of 2 patents. His work has been instrumental in enhancing the efficiency and functionality of various hydraulic applications.
Latest Patents
One of McGovern's latest patents is the "Electrical Trigger for Quick Drop Valve." This invention features a quick drop valve that is electrically actuated by a switch located adjacent to the implement positioning control lever. The quick drop valve operates as a pilot-operated spring-biased valve. When the electric switch is closed, a solenoid valve is energized, redirecting fluid between the pilot control lines. This mechanism allows for the rapid dropping of the working implement by short-circuiting the flow of fluid from the lift side of the hydraulic cylinder to the reservoir and redirecting it to the drop side.
Another significant patent is the "Secondary Hydraulic Steering System." This system is designed to be automatically triggered and manually actuated. It includes a dual displacement fluid meter equipped with a fluid pressure sensing valve that selects the operational configuration for the fluid meter. The fluid pressure sensing valve is hydraulically coupled to the source of pressurized fluid. In response to a loss of fluid pressure, it shifts the dual displacement fluid meter into a reduced displacement configuration, providing the operator with greater mechanical advantage.
