主　　题：Electro-hydraulic proportional control Proportional flow valve Proportionalpressure valve Pressure and flow compound control 

摘      要：A new closed loop flow controlling principle through correcting the valve sopening area while load pressure is changing is carried out. Further more a principle using only oneproportional valve to compound control pressure and flow is suggested. By using very simpleproportional throttle valve in structure, the functions that five kinds of proportional valves orany two of them combined possess can be complimented. After analyzing, comparing, and testing thedynamic and static characteristics of valve with different controlling principles and main valvestructure styles, the optimized structure styles and control methods are achieved.
