Quick Dump Valve
Posted: Sat Apr 04, 2009 8:01 pm
I have been working on a different valve style to overcome some high speed air flow problems. I have a youtube video of the valve. I originally built a 2 inch version for a competition. I just completed a smaller version that shoots marshmallows. It explodes full soda pops. It punches holes through empty pop cans and busts out the bottom of 5 gallon poly pails all while using marshmallows for ammo.
Here is a video of how it works. The construction details will come later.

I am working on a larger one using a higher pressure tank, an old Propane tank.
This is a working model of the 2 inch version built for a t shirt launcher competition. I have the 2 inch prototype shown in the video. The school entry that won the competition is shown in this video. They show the breech loader more than they show the valve. Note the trigger is pulled just like the little model.

At the very end on the video when the camera turns sideways, you can catch my camio shot with the prototype.
***Edit The thread on using o rings is started. The video for it demonstrates the friction in this valve.
