Abstract

The present invention relates to a bidirectional output mixed hydraulic power system, which includes a hydraulic fluid that stores and contains therein a fluid tank; at least one electrical hydraulic pump connected to the fluid tank to draw in, pressurize, and output the hydraulic fluid; at least one mechanical hydraulic pump connected to the fluid tank to draw in, pressurize, and output the hydraulic fluid; at least two sequence check valves each connected to the electrical hydraulic pump and the mechanical hydraulic pump, each of the sequence check valves being set normally open in a first direction and preventing fluid returning in a second direction; and a dual pressure valve that is connected to the fluid tank and each of the sequence check valves for switching output direction of the hydraulic fluid.
