That looks spot on, can't seem to find any specs on pressures etc and i don't know enough about car injection systems to know if it's suitable for our applications. However, its just the idea that i was getting at, does anyone know how hard it would be to make something simmilar?
I found a little antique brass mist gun around the house which produces a really fine mist ( i think it was for ferns or orchids) - much finer than the nozzles you get on standard gardening misting bottles. It works by having two slots which twist in a spiral, cut out of the side of a cylinder. This then fits snugly into the cap with the fine hole, which in turn screws onto a male thread with a central bore that leads to the pump. (i haven't got a digicam so i cant post a pic
and its victorian apparently -so i can't get any more
)
If we (or i can con an engineer into it), and can combine the two ideas - have the victorian nozzle with a high pressure air feed to one slot and a high pressure neut feed to the other.
I'd draw it but i'm rubbish with paint!
I hope someone knows what i mean! (do i make any sense or am i too mashed) Is it possible?
