Bolt action propane injection.

Unread postAuthor: SpeedyFerrite » Tue Apr 17, 2007 3:30 am

I have devised a way for precise propane injection using a measuring chamber on a slide, it's kind of difficult to explain and you'd probably not understand my idiotic way of stating things, so I have prepared a little flash animation.

You can use different sizes of fuel chambers for different sizes of combustion chambers.

Pin valves?

I'd be using the little things lighters have to refill, if that's what you mean. :)

it would be tough to meter the exact amount of fuel, plus you'd need an effective way of venting the chamber.

To vent th chamber you could maybe fit a schader ing the chamber wall and hook it up to a compressor?

If your getting chased off a police dog, try not to run through a tunnel then onto a small see-saw then through a ring of fire. They are trained for that!

now i can see the animation, so I'd have to say that this is not regulated so a regulator must be attached first, you can still have a pin valve by attaching a tire chuck, and a schrader and on the other side a schader and a pin
