PNEUMATIC GUN WITH VALVE QEV

[keks2033]

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

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":

A few days ago, I managed to make and test a piston valve with a caliber of 40 mm. I managed to make an exit into the barrel with a diameter of 14 mm. I pumped 50 atm into a cannon with a homemade pump.
