Title: Innovations of Richard Grau
Introduction
Richard Grau is an accomplished inventor based in Kalamazoo, MI (US). He holds three patents that showcase his expertise in flow control valve technology. His innovative designs have contributed significantly to the field of electromechanical systems.
Latest Patents
One of Richard Grau's latest patents is a two-position flow control valve assembly with position sensing. This invention includes a valve that has open and closed positions, utilizing a limited angle torque motor with two stable angular rotor positions. These positions correspond to the open and closed valve states, which remain stable without an applied electrical signal. The design features magnetic pole pieces that form a concentric shell around the motor shaft, with air gaps aligned parallel to the shaft's axis of rotation. Additionally, the assembly incorporates a magnetic flux sensor that uses a high-frequency electrical signal to determine the relative rotor and valve position. Another notable patent is a control valve assembly that includes a valve position sensor. This electromechanical valve assembly employs an actuator, such as a limited angle torque motor or solenoid, to operate the valve in response to electrical signals. The position sensor detects the valve's position through a second, relatively high-frequency electrical signal.
