But this is exactly how Rob's window walker worked. I had the privilege
of seeing it first person, and he would work the pump a bit (to take air
out of the blue tanks), then start it going. Then after a while, he
would work the pump more. This is the same as any regular pneumatics
application (in which you build up pressure, then run for a bit, then
build up more).
I don't know if this will help or hurt my argument, but here it is:
When you use any regular pneumatics device, you are applying exactly the
same principle as the winodw walker. You are relying on the fact that
you have enough pressure in your system pushing your cylinder outwards
to counteract the air pressure pushing in the opposite direction.
I hope ive explained my point clearly :)
