(...) It is my understanding that fliuds cannot be compressed. So a cylinder hooked to another cylinder with fluid in between (assuming no leaks), would always provide 1 to 1 movement. I'm not an expert in hydraulics, but I think your claim above (...) (20 years ago, 8-Apr-04, to lugnet.technic)

(...) I have created a pneumatic polarity reversor using four pneumatic switches. I did an analysis and my pneumatic multiplexor works as a hydraulic switch that does not have a free release. (URL) above picture contains two pneumatic multiplexers. (...) (20 years ago, 8-Apr-04, to lugnet.technic)
