Pneumatics exhaust usage

Is it possible, (or legal) to connect the exhaust from a pneumatic solenoid through a directional valve back into the airflow? Would be used to contain as much air as is possible, but on the solenoid the exhausts are too close to the (air supply in) opening. It is not legal to modify any of the solenoids, pistons, or reservoirs, but I was thinking of melting some of the tubes and attaching it that way, maybe some metal to hold it in place.

The air cylinder will not move if you block the exhaust, either at the air cylinder or at the solenoid valve. This is the method in which the exhaust flow control valves work to slow down the speed of an air cylinder when it actuates. The idea of trying to collect the exhaust from the air cylinder to reuse, is a little bit like plugging a power bar into itself hoping for an endless source of electricity.

The British patent office has a no-review policy on perpetual motion machines, but nice try. While it’s definitely legal, you have to lose air at some point for this to work. If you need more air, a better idea might be to redesign your mechanisms, or, dedicate a motor as an air pump (which could work).

While this might be a better strategy, it is also against the rules to use a motor (or anything) as an air pump.

so it would seem that I am stuck with a total of 100 psi.

I am pretty sure that the guidebook bans devices meant to generate air pressure in the name of safety, but I may be mistaken.

Yes, I believe this is correct. I should have clarified that in my post. Thanks for the catch. The rule is, however, somewhat vague, but I’m not condoning pushing it.

No generation, sadly. I don’t know how we would push that.
