Title: Warren A. Lederman: Innovator in Fluid Signal Technology
Introduction
Warren A. Lederman is a notable inventor based in Wauwatosa, WI (US). He has made significant contributions to the field of fluid signal technology, holding 2 patents that showcase his innovative approach to engineering solutions.
Latest Patents
One of his latest patents is the "Fluid Signal Transmitting Apparatus." This invention features a fluid signal inverting unit that includes a motion balance unit with a lever operating a valve. The balance lever is supported by a pilot signal chamber and a feedback signal chamber, allowing for precise control of output pressure. Increases in pilot pressure lead to the outward movement of a linear diaphragm, which in turn opens the valve and results in an inverted output pressure signal. This signal can be amplified and transmitted to a flow booster relay, providing effective feedback control.
Another significant patent is the "Fluid Relay Apparatus." This control valve utilizes a single diaphragm as a common wall between an input signal chamber and an output chamber. The design includes a spring-loaded ball valve unit that operates in conjunction with the diaphragm. As the input signal increases, the diaphragm first closes the exhaust orifice and then opens the supply valve, allowing pressure to build in the output chamber. This innovative mechanism ensures minimal leakage while maintaining high flow capacity.
