simple semi-auto valve

I found this design at NerfHaven and it's someone elses. It looks like an awesome/simple design though. What do you think?

It looks simple enough, but that site also tells you how to make a little more complex one, but it's still basically the same design.

I bet the design above lets the air out a lot faster than the zero valve but I dunno.

All the nerf haven designs suck. It would all have to be perfectly sealed. You would need a lathe.

A spool valve attached to a 'trigger' to provide linear movement. Ive designed several gun designs of my own using spool valves. I even have a lathe and everything, although I have yet to construct one of the idears. As previously stated, such seals have to be precise as to provide a good seal, and able to slide. Without a lathe, such designs are out of your capabilities...

k, I'm just going to stick with the zero semi valve. I've already made half of it anyway.
