Title: Innovations of James Leroy Davison
Introduction
James Leroy Davison is a notable inventor based in Freeland, MI (US). He has made significant contributions to the field of vehicular hydraulic systems, holding a total of 12 patents. His work has been instrumental in advancing hydraulic technology in the automotive industry.
Latest Patents
Among his latest innovations is the "Vehicular hydraulic system with priority valve." This system features a pump and first and second hydraulic applications arranged in series. A valve is designed to allow fluid from the pump to flow through an inlet port, primary flow channel, and outlet port to the first hydraulic application. The valve includes a body and a valve member that axially slides within an elongate valve chamber, effectively partitioning the primary flow channel from a low-pressure volume. Additionally, the valve incorporates a low-pressure port and a bypass port, which is sealed from fluid communication in a first position and opens to the primary flow channel when the valve member is biased into a second position by elevated fluid pressure.
Another significant patent is the "Vehicular hydraulic system with dual relief valve." This system also includes a hydraulic pump and first and second hydraulic applications arranged in series. A dual relief valve defines first and second flow channels, a passageway, and a bypass port. The first flow channel is positioned between the hydraulic pump and the first hydraulic application, while the second flow channel is located between the first and second hydraulic applications. The first valve member controls fluid flow through the passageway, allowing fluid to flow from the first to the second flow channel when pressure exceeds a first threshold. The second valve member manages fluid flow through the bypass port, enabling fluid to return to the line when pressure in the second flow channel exceeds a second threshold.
