Latest Patents

Gold's latest patents showcase his expertise in creating efficient and reliable hydraulic systems. One of his notable inventions is the "Multistage Servovalves," which incorporates two and three-stage designs. These servovalves feature a first stage consisting of a torque-motor driven, double jet, flapper valve. By using active flow controllers, Gold successfully improves dynamic response by maintaining a consistent flow rate even under varying pressure conditions. This innovation reduces the flapper to nozzle null gap, allowing for increased gain of differential pressure to flapper displacement while minimizing torque-motor centering spring force.

Another significant patent is the "Hydraulic Fuse Valve Assembly," designed to provide quick shut-off of fluid flow during rupture or failure of fluid-conducting lines. This fluid fuse utilizes a pressure differential to move the valve member from an open to a closed position. Gold's design emphasizes safety and efficiency, with features such as limited freedom of alignment for tight sealing and a manually adjustable bypass arrangement. These developments have proven essential in enhancing the reliability of hydraulic systems.
