We've all been there. Grab an irrigation solenoid valve and pull it apart. The principle is the same.

Yes and No....a valve is a valve and the forms of actuation are limited.

But your right that the principles are the same as some of these.

Kind words thanks Glen.

I think you will find gentleman that maybe for our application (robot combat) pneumatic design hadn't been optimized yet in terms of flow.

Now with efforts of others I have been able observe there designs and attempts, ask questions and come up with something that meets the max potential of a given ram.

The keys for me were Mario's practical knowledge and proven ram components. The quick exhaust valve concept. And Woody's math for the max flow needed for a ram, BUT NO MORE than needed.

May I just be so bold and to say. If you can design a bot to handle the force, you can have the max potential of the ram with a valve that weighs no more than a burkett.

With Trent's permission I've added a quick update to my 2nd pneumatics page.

I'll add more detail as / when Trent makes it available.

Total? About 200mm, quite long. New designs have reduced this.
