摘　　要：提出了一种新型的脉冲数字流,其量化单位可用二进制代码的形式进行改变或调节,从而使流体系统中的工作介质转变为真正完全的数字式流体。设计了代码形式的电—流体脉冲发生器。该种形式的脉冲数字流不但可以控制各种流体动力元件,使它们成为数字式的流体元件,而且可以对流体系统的负载流量、执行机构的工作速度等进行数字化的设定和控制,因而对于构建完全的数字流体系统、加速流体系统数字化的进程有着重要的意义。A new digital flow of pulses was presented. Its quantization unit was able to be changed and regulated by means of binary code. With the binary-coded electro-fluid pulse generator designed here,the working medium in hydraulic systems was turned into completely digital fluid. The digital fluid can be used to control various fluid power components and make them into digital ones, and the load flow in a fluid system and the working velocity of executive mechanisms can be numerically set and controlled. Therefore, it is of great significance to develop entire digital fluid systems and speed up the process of the digitalization of fluid power systems.
