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.

本项目是一种新型结构的直动式溢流阀，采用动压反馈原理，在普通直动式溢流阀阀芯上增加一反馈腔，当阀口溢流时，阀口的液压力与反馈腔液压力和弹簧力相平衡，从而可以减小弹簧的刚度，等于增设了一根液压弹簧，使其和机械弹簧一起工作，以达到减小阀口压力变化范围的目的。
