Sweet. My design doesn't use a spring to close, it uses air pressure on the small piston side. I am pretty uneducated in this stuff but from what I gather it sealed off the chamber from the barrel with the piston, that was inside the barrel and the ports were in the barrels' breech behind the pistons' o-ring so the pressure couldn't escape until the piston moved back, no? If so I still cannot tell how it was opened. Overall, good job... even if it was a whimpy launcher at least you got to see your piece of work do its' thing.

You got the design correct. It works by venting the air from the very rear pilot area. Air at the chamber pressure between o rings tries to escape. The larger diameter rear seal has larger area and thus more force against the barrel end seal when the pilot is vented. This force moves the piston to the rear opening the barrel valve ports to the barrel..:: :TomDom: ::. wrote:Sweet.

This is a long version of a barrel sealer piston. Wish it performed half as well as it looked.
