摘　　要：根据数字液压驱动单元的运行原理,分析了在空载与加载情况下该数字驱动单元的内部液体流动状态,并以这一流动状态原理为依据,改进设计了传统的液控单向阀。数字液压驱动单元样机及试验结果表明:该数字液压驱动单元与应用传统液控单向阀体的驱动单元相比,具有更加紧凑的体积、更高的响应速度及运行可靠性和显著的节能效果。In the light of the operational principle of a digital hydraulic-drive cell, we analyze the liquid flow status inside the cell under the conditions of no-loading and loading. Based on the flow status, we improve the design of a conventional pilot valve. The results of experiments on the prototype cell indicate that the novel digital hydraulicdrive cell is more compact and has higher response speed, better reliability and energy-saving effect than the drive cell that uses the conventional pilot valve.
