Air Cartridge Design

(1/4) > >>

DarwinsLaw:
Hi all, I realize there have been many posts about air cartridges and I hope I am posting this in the correct section.  I just wanted some opinions on my design. 

Gippeto:
Is the drawing complete or have you left out details that might clarify the operation cycle?

I presume the spool_striker is to be hit by a firing pin of some sort, but then what? How do you see the valve opening?

DarwinsLaw:
Yes the striker will be struck by a hammer or firing pin set up of some sort.  I assumed that the striker would create a vacuum essentially and open the valve as with other air cartridges.  I honestly don't know that much about it other than what I have read on here. 

DarwinsLaw:
There is a strong possibility that I missed something or misunderstood the Lupra design.

rsterne:
In order for the valve to open, you must have more area at the back of the valve rod than the front.... You also need to vent the chamber behind the rear O-ring to the atmosphere to initiate the firing cycle....

The big drawback of air-cartridge designs is that they are limited in power by the small reservoir of the cartridge.... If you make that large enough, then you face terrible efficiency....
