Title: The Innovations of Charles B Tidwell

Introduction

Charles B Tidwell is an accomplished inventor based in Durham, NC (US). He is known for his significant contributions to the field of mechanical engineering, particularly in the development of advanced shock absorber technology. His innovative approach has led to the creation of a patent that enhances the performance and efficiency of shock absorbers.

Latest Patents

Tidwell holds a patent for "Valving for a controllable shock absorber." This invention features a controllable shock absorber of the externally actuated type with greatly decreased valve response time. The shock absorber assembly utilizes valve rotation stops on the rotary valve to limit the rotational motion of the valve. The valve is attached to a bendingly flexible control rod, supported by a sealing and support assembly located inside the piston rod. This design allows for easy assembly of the rotational motor through a bendingly alignable self-locating feature. The use of a single seal and support assembly further reduces the rotational forces needed for faster actuation of the valve. Additionally, the valve actuation torque requirements have been decreased by minimizing viscous drag on the valve body and reducing the inertia of the rotational valve assembly by hollowing out the valve. Performance robbing side loading on the valve is minimized by using at least two symmetrical ports. Further reductions in friction are achieved through pressure-equalizing grooves on the valve body, which reduce hydrodynamic axial loading.
