Just to be sily, it would take a fairly large valve to do this with air. (at least the controlled profile valve chamber injection)
Maybe feed a diesel injector with liquid CO2? That would allow use of common parts for testing. IIRC, they've started using peizo technology in that sort of injector to allow them very precise timing. And a carefully controlled fuel curve.
Perhaps a simple/cheap solution would be to run two different valves, one for slow injection, one for fast injection. Or, with a $8 servo, you could potentially move a valvebody to switch between quiet pressure rise and fast pressure rise. that may be cheaper than going with a crazy injector capable of being driven with PWM and still give the same quiet-fast switch.
Aprillia has done high pressure air/fuel emulsion injection, that might have some relation to what we're looking at here.
Would a single port be enough to setup a consistant spin? Would a carefully designed groove do better?
The controllers to do this are out there... You'd need to step it up from the low end pics and avr's that are common now, and you'd probally need to revive the emag style battery pack. This could go places..
There we go, Tom's got me thinking again.
Excuse me while I go look at injectors...
EDIT: This would also allow for a player to "fix" paint breakage issues on the fly. If you're breaking paint, hit a button, goto delicate mode, and now you can shoot eggshells.
EDIT again: And why hasn't anyone introduced damping into guns? it seems that companies are finally starting to address how the guns "feel" to the user. the last time I saw anything that really addressed damping were the timing shocks on the tippman F/A.
