| (...) This is a good question. When using traditional pressure only, the force producde by the air pressure on the faces of the pistons is enough to flip a switch. Just yesterday someone asked me "If instead of using pressure, you used vaccume" (...) (19 years ago, 17-Nov-05, to lugnet.technic)

| (...) Just out of curiosity, how would one go about creating a continuous vaccume? A temporary one can be created inside a piston by clogging one end, but how could one create a continuous vaccume? Would this need to be done in, say, an accumulator (...) (19 years ago, 17-Nov-05, to lugnet.technic)

| (...) Hi Dr. Soh, Nice to hear from you. I've never actually built with the original pneumatics, but my understanding is that the way to use switches in the old pneumatics is different than the way you use them with dual ported pistons. Don't you (...) (19 years ago, 18-Nov-05, to lugnet.technic)

The pneumatic switch is basically a directional control valve. It (...) (19 years ago, 19-Nov-05, to lugnet.technic)

That's because a suction force acts in the opposite direction to the traditional compressed air. Your walker will then (...) (19 years ago, 19-Nov-05, to lugnet.technic, FTX)
