Title: Innovations of Michael D. Herder
Introduction
Michael D. Herder is an accomplished inventor based in Kalamazoo, MI (US). He holds two patents that showcase his expertise in fluid control systems. His innovative designs have contributed significantly to advancements in actuator control systems and flow control valves.
Latest Patents
One of his latest patents is a fluid control valve with variable pressure gain. This actuator control system features two parallel connected orifices that facilitate communication between an actuator and a flow control valve. The design includes relief valves in series with the orifices, which block fluid flow at low differential pressures, preserving the high pressure gain of the control valve around the valve null region. At higher differential pressures, the relief valves open to allow restricted flow, effectively reducing the stiffness of the control valve.
Another notable patent is for fluid control valves with angled metering ports. This design incorporates angled metering ports in the valve sleeve, directing the momentum of fluid flow against the valve flow metering edges. This configuration produces an opening reaction force on the valve during initial opening, counteracting the axial flow forces that typically tend to close the valve. The angled metering ports are ideally positioned at approximately 45 degrees or greater from a line perpendicular to the valve axis.
