Just out of curiosity, how would one go about creating a continuous vaccume?
|
The older style pumps didn’t have a built in waist valve.
If you connect an older pump to your compressor, then a hose from the pump to
the centre port of the 2x4 “distribution block”,
one of the other ports (i can’t remember which one, it’s been a while) will have
continuous suction which was normally inhaled at the switch. Connect this port
to your air tank(s) instead. This is how the older style pneumatics had
“controlled” contraction of the rams; by removing one pump-cylinders volume of
air from the ram (with the exception of valve loss).
I have about 6 of these check valves and they all have high volume valve loss.
Given that they are at least 18 years old, i don’t really care. With any luck,
the valve you need (as they have two valves, input and output), will be a good
one (you’ll only need one, the input).

Would this need to be done in, say, an accumulator (...) (19 years ago, 17-Nov-05, to lugnet.technic)
