Title: Richard G Thrush: Innovator in Brake System Technology
Introduction
Richard G Thrush is a notable inventor based in North Olmsted, OH (US). He has made significant contributions to the field of motor vehicle brake systems, holding two patents that showcase his innovative approach to enhancing vehicle safety and performance.
Latest Patents
One of Thrush's latest patents is the "Blend Back Proportioning Valve for Brake System." This invention features a motor vehicle air brake system that includes a blend back proportioning valve designed to reduce brake sensitivity at low braking pressures while allowing full braking at high pressures. The valve comprises a shuttle piston, a blend back sleeve, and a one-piece outlet diaphragm that seals a reference chamber from outlet pressure. This design permits coordinated movement of the shuttle piston and blend back sleeve, as well as independent movement between them. Additionally, the valve includes a one-piece inlet diaphragm that seals the reference chamber from inlet pressure, providing a valving surface to control communication between the inlet and outlet. In alternative embodiments, springs are incorporated to modify the valve's proportioning characteristics.
Another significant patent is the "Inertia Load Sensing Brake Valve." This hydraulic brake system includes a master cylinder that supplies fluid pressure to both front and rear brake circuits. The rear circuit features a proportioning valve that reduces pressure to the rear wheel brakes. A control circuit modifies the operation of the proportioning valve when front and rear braking pressures exceed predetermined levels. This ensures that the proportional relationship of the valve approximates a 0.4g deceleration line until the ideal front-to-rear pressure relationship is achieved for the vehicle's loading condition.
