The invention provides an electrical control rectifying valve of a hydraulic electric feed energy shock absorber. The electrical control rectifying valve comprises a hydraulic cylinder, a rectifying valve, pressure sensors of an upper cavity and a lower cavity of a piston, a control unit and guide wires. The working principle of the electrical control rectifying valve includes that energy generated from vibration of the hydraulic cylinder is converted into hydraulic energy, the hydraulic energy is passed in a system via liquid flows, the flowing direction of liquid at the front end of the rectifying valve is judged by utilizing the control unit to compare pressure signals acquired by the upper-cavity pressure sensor and the lower-cavity pressure cavity, the spool position of the rectifying valve is controlled via an electromagnetic valve, liquid flows from a shock absorber cylinder are rectified, the liquid flow rectified is capable of driving a hydraulic motor to work towards another direction to drive a generator to generate power, and thereby vibrating energy is converted into electric energy to be recovered. The electrical control rectifying valve is specially designed for the hydraulic electric feed energy shock absorber, rectifying is realized via controlling an algorithm, over-impact to a spool when the liquid flows reverse is avoided, service life of the valve is prolonged, and meanwhile, a reversing time of the spool is precisely controlled, and the hydraulic energy is fully utilized to recover the vibrating energy.
