(...) I'd love to see a picture of your reversor, as verbal explanations by themselves are often much harder to comprehend. (...) Again, I'd like to see this. My pneumatic mux that can act as a polarity reversor, can just as easily be used for an (...) (20 years ago, 8-Apr-04, to lugnet.technic)

(...) The amount that a fluid can be compressed varies with the fluid, the temperature, the pressure and other things. Water can be compressed too much - that's why trucks don't use it for their hydraulic systems. Hydraulic fluid is special oil that (...) (20 years ago, 8-Apr-04, to lugnet.technic)

(...) I get the impression you've complicated things by putting different switches at different lever angles. My reverser idea puts the switch lever pivots 16mm apart, all in a line with 2-beams between: BSBSBSBSB along a beam of length 17 holes, so (...) (20 years ago, 8-Apr-04, to lugnet.technic)

(...) 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)
