Title: The Innovative Contributions of Stephen E. Dourson
Introduction
Stephen E. Dourson is a notable inventor based in Dayton, Ohio, with a significant portfolio of five patents. His work primarily focuses on advancements in hydraulic damping technology, showcasing his expertise and innovative spirit in the field.
Latest Patents
Dourson's latest patents include an "Internal Accumulator for a Hydraulic Damper." This invention features a hydraulic damper that incorporates an internal accumulator designed to store and dissipate energy resulting from fluid pressure spikes. The design includes a housing mounted on a piston rod above a reciprocable piston, with a compressible medium stored within the housing. A valve assembly regulates the fluid flow into and out of the accumulator, allowing the medium to compress and store energy during sudden pressure rises, and subsequently release it as the pressure dissipates.
Another significant patent is the "Low Level Damping Valve and Method for a Semi-Active Hydraulic Damper." This invention utilizes a solenoid valve assembly to control fluid flow through a bypass channel. It also includes a blow-off valve assembly that works in series with the solenoid valve to provide low-level damping when the bypass channel is open.
