From the good old days of Spudfiles.com and Patator' Forum (patator.1fr1.net)
Initial conceptual design of a more efficient alternative to the pop-off exhaust valve.
(You may have noticed it isn't really manufacturable in one piece as modelled)
The valve shuts off the air inlet before piloting. The firing pressure is adjustable.
The design was never finished or built and I moved on to use solenoid valves with an Arduino for timing.
