I'm pondering the actual mechanics of the gas check plate. I suspect the gas check plate is forced shut under pressure in s similar manner as a dump valve; equal pressure on both sides of a valve diaphragm....bleed off pressure on one side and wham, the dump valve opens. In the instance of the gas check plate the differential between the check plate and the powder chamber is surface area over length. The gas check plate "chamber" has a larger diameter than the chamber and has the ability to move...under wham pressure it does move thus sealing the breech.
I have a pedersoli sharps with the latest o-ring version of gas check plate and an IAB sharps that I just did an o-ring job on. The IAB has a bigger diameter check plate volume. I think it also has a chamber sleeve. It doesn't move. Anyone know if IAB circa 1994 used both sleeve and plate?
It's been said the pedersoli does not seal well. The "chamber" of pedersoli's check plate is smaller in diameter than the powder chamber. May be the reason it doesn't work well.
This is speculation on my part, anybody have any thoughts on this subject?
