In need of a fresh perspective- remote inflation and release of balloons

<< < (8/8)

Well I had decided to go with two plastic plates positioned on top of each other with holes drilled in them for the one way nozzles for the balloons, one plate would be fixed and the other would be motorized to pinch the nozzles.. But for the life of me I couldn't think of a way to keep pressure on the connection between the line for the gas and the nozzles themselves, not to mention it would have had to be about 66" to accommodate as many balloons as I wanted.  Then I thought of a whole new design that solves such problem. I'm going to have two pvc tubes, one that fits inside of the other almost perfectly, so not too snug so they cant move. Same idea with pinching the nozzles,but this way I can seal the ends of the tubes and the whole assembly will be pressurized during inflation. I have a worm gear motor coming in from Amazon, and I'm going to see if I can special order a rack and pinion gear that will fit with my motor to move the inner pvc tube to apply pressure to the nozzles. Possibly add a thin layer of silicone caulk around the edges of each hole as makeshift gaskets. I've attached some crude drawings I did at work today instead of my actual job.

Had a very quick look online these valves look easier to lock onto your manifold due to the step in the inflation tube. Drop an o'ring in the stem section somewhere to retain the gas while inflating.



And use a driven comb like this below actuated by solonoid/s or to retain and release?

So I was bored with cleaning up my shack  ;) Coffee and CAD ideas.
