特许45～3859(摘要)获得专利的发明是由简单调节任意输入脉冲信号的振幅来变换持续时间就能取得流体输出脉冲信号的装置。如图所示,由流体压力供给口22供给的流体通过共同通道23在控制口32没有控制信号(输入脉冲)时,流体通过口34时由于可变容积室36内是负压值,所以就向输出脚部28方向流动。当在控制口32上给控制信号,并使其于共同通道23流出的流体一部份在可变容积室内形成偏流时,由于室36内正压力
Patents 45-3859 (Abstract) The patented invention is a device capable of obtaining a fluid output pulse signal by simply adjusting the amplitude of an arbitrary input pulse signal to change the duration. As shown, the fluid supplied from the fluid pressure supply port 22 passes through the common passage 23 when there is no control signal (input pulse) at the control port 32 and when the fluid passes through the port 34, since the inside of the variable-volume chamber 36 is a negative pressure value Flows in the direction of the output leg 28. When a control signal is applied to the control port 32 and part of the fluid flowing out of the common passage 23 forms a bias current in the variable volume chamber, due to the positive pressure in the chamber 36
