Title: The Innovative Contributions of Ronald G. Davis
Introduction
Ronald G. Davis is a notable inventor based in Anderson, IN (US). He has made significant contributions to the field of solenoid valve technology, holding a total of 4 patents. His work has been instrumental in advancing the functionality and efficiency of solenoid valves used in various applications.
Latest Patents
One of Ronald's latest patents is for a solenoid valve assembly. This innovative assembly features a slidable valve member that responds to a selectively energizable solenoid coil and a spring. It effectively controls the opening and closing of pressure and exhaust ports through the movement of the valve member. When the pressure port is fully opened, the valve member is seated against a solenoid stop and port member. This design includes a central flow passage that serves as the exhaust passage for the valve assembly. The surrounding valve seat area features a frusto-conical surface with a recess or groove, which reduces the flow forces acting on the valve member. This reduction in flow forces minimizes the unseating force required to open the exhaust port, resulting in lower spring and magnetic forces.
Another significant patent by Ronald is for a spring and washer device. This device facilitates the pin-type cantilever mounting of a solenoid valve with a tubular plastic body on a transmission control valve body. The solenoid valve's plastic body houses a relatively heavy coil at one end, which is plugged into a pressure bore in the control valve body. This design allows the coil to be supported in a cantilever beam fashion. The spring and washer device is snap-fitted over a minimum wall thickness flux gap portion of the plastic body. It includes a flat washer portion that bears against a flange on the plastic body, while integral spring arms bear against the coil body on the opposite side. This configuration preloads the flux gap portion in tension, balancing the dynamic beam bending forces that occur during normal vehicle operation.
