Latest Patents
One of Charles Eric Nail's key patents is the "Articulation system for an earthmoving machine." This invention features a hydraulic circuit designed for a pair of cylinders within an articulation system. The system includes a pump, a reservoir, a directional control valve (DCV), a pair of actuator valves (AVs), and an articulation charge circuit (ACC). The DCV is fluidly coupled to the pump, the reservoir, and the pair of cylinders through a supply line, a fluid return line, and a pair of cylinder supply lines (CSLs). Each CSL contains a load check valve (LCV). The AVs are connected to the DCV and the pump via a pilot supply line (PSL) to actuate the movement of the DCV. The ACC, which is associated with the PSL and each cylinder supply line downstream of the corresponding LCV, charges each CSL with fluid from the PSL to increase pressure when it falls below the PSL's fluid pressure. This patent showcases his innovative approach to enhancing the functionality of earthmoving machines.
