Latest Patents
Lifei Yu holds a patent for a "Method and system for electrohydraulic valve control." This patent describes an electrohydraulic valve control system that enables simultaneous flow and pressure control for operating implements or other work elements associated with work machines. The system utilizes a single control valve design, which compares the actual valve output flow rate of hydraulic fluid to a desired output flow rate. It then modifies the input flow rate based on the difference between these two rates. The desired output flow rate is determined by the actual load pressure exerted against the implement and the operator's input signal. The control system also stores multiple pressure-flow curves to optimize performance.
