Response to A question, Gippeto
There's no easy way to adjust it without machining pieces. The spool, spool bore piece and chamber volume are the major tuning tools as I see it.
Spool travel would be set initially such that "open" area is equal to bore area + ~ 10%. Should be close enough for a start.
Bottom line is that the valve is going to remain open until the chamber pressure drops and creates the force differential to close the valve. A spring could be added to fine tune this point, but I would personally like to avoid the use of springs.
A paintball type regulated N2 tank is supposed to be threaded into the valve body on the left. Some tuning will be done by adjusting the regulator setting.
