This item is a new type structure direct-acting overflow valve, which adopts dynamic pressure feedback principle. That is it adds a feedback cavity on common direct-acting overflow valve's core. When there is overfall on valve port, the hydraulic force of valve port will balance with feedback cavity's hydraulic force and spring force, so it can decrease spring's stiffness, just like adding a hydraulic spring, which works together with mechanical spring, so as to minish valve port pressure range.
