Title: Richard L Foster: Innovator in Hydraulic and Brake Systems

Introduction

Richard L Foster is a notable inventor based in Beavercreek, OH (US). He has made significant contributions to the field of hydraulic systems and braking technology. With a total of 4 patents to his name, Foster's work has advanced the performance and efficiency of braking systems in vehicles.

Latest Patents

One of Foster's latest patents is for a performance hydraulic system designed for hybrid brake systems. This innovative braking system includes a pre-charge with multiple pumps arranged in parallel. These pumps can direct pressurized brake fluid to the brakes during controlled braking maneuvers. The design features offset operating cycles, allowing one pump to draw fluid while another pushes it to the brakes. This system includes three pumps operating in parallel, with their cycles offset by 120 degrees. Additionally, it incorporates a separate master cylinder reservoir feed circuit to enhance system response, particularly in cold weather.

Another significant patent by Foster is the bi-modal DC motor control for a motor-driven anti-lock brake system. This invention achieves differential performance characteristics using a DC motor with three brushes. The first brush is used for both forward and reverse motor rotation, while the second and third brushes are employed for specific motor directions. This arrangement maximizes motor torque for developing required brake pressure and optimizes motor speed for quickly retracting the armature to relieve brake pressure.
