Alternativeley you can continue using the valve with the old style pump and
have an air tank (if you own two) on each side i.e. one that holds the
vaccum and one that holds the pressureized air. but... theres still the
problem of flipping the valve every time... maybe it could be motorized and
then all you have to do is pump the compressor at the same speed the valve
moves. would this work on the non return valve, as I do not have one it is
kind of hard to test this :)

While you can pressurize a tank to several hundred PSI or better, for vacuum you're limited to completely (well, OK, nearly completely) evacuating it--a (...)

| Instead of pushing a pneumatic switch back and forth, you can use the old non-return valve: (URL) the pump to the middle hole, connect the air tank to the left hole and leave the right hole free. The old style pump will pull air out of the tank and (...) (23 years ago, 18-Dec-01, to lugnet.robotics, lugnet.technic, lugnet.build)
