Hello pneumatics fans,
I have been working a lot with pneumatics lately, and have made some
interesting discoveries. I think the most notable is a method of using the
old style red cylinders with the new pneumatics system. I came across this
as I was working on a recent robot, and I wanted to minimize the amount of
air required. There was a thread not too long ago about pneumatic check
valves, creating a vacuum, etc. When I read this post:
http://news.lugnet.com/robotics/?n=16764
It jumped out at me. C.S. Soh was saying you can't use the old single acting
cylinders with air tanks. Not true! I wanted to reply, but I didn't have any
pictures up on my site at the time, so I have waited until now. Anyway, have
a look:

On the pneumatics page, you will also see some unusual compressor designs
and a valve switching unit that controls two valves with one motor.
Eventually I would like to make Ldraw instructions for this unit, as it is
very useful and reliable. You can see an application of the single acting
cylinder here:

Oh yeah, this is old news, but if you want to see an application of vacuum
tanks, see my window walker:

Enjoy,

| Wow!! That is a fantastic model, it's a shame they're not produced anymore - I wonder if TLG would be capable of manufacturing parts which function the same way as the old ones did? If it were possible to obtain new parts that performed the same (...) (23 years ago, 2-Mar-02, to lugnet.technic, lugnet.robotics)

| Hi there, Rob That thread led to an extensive discussion into the depths of "vacuum storage". It would appear that storing compressed air is no problem but 'the whole concept of "storing vacuum" is a little disturbing.' Well, you can certainly pump (...)

| Very nice design. I don't have access to old style pneumatic cylinders, but was thinking of doing something similar with the new double acting cylinders. Because I don't have a check valve in the new pneumatics that would allow me to store vacuum, I (...) (23 years ago, 10-Mar-02, to lugnet.technic, lugnet.robotics)
