PNEUMATIC GUN WITH VALVE QEV

Unread postAuthor: keks2033 » Mon Nov 19, 2018 2:50 am

Made a gun of 40 mm caliber, used a piston valve. The gun works well at pressures up to 20 atm, no longer possible, because the rubber on the piston is torn.

here is an approximate diagram of the valve. Used a coarse water filter.

I like it for the simple. Good job! Perhaps the air pump built into the launcher is missed :roll:

Actually I'm planning the improvised, and improvising what's planned!

Nice work! This configuration is rarely used, I think I've only ever seen it done by clide on this forum, what he called the "straight-through valve":
