That's what I was thinking.
It would be a mechanical valve, but having some type of hydraulic/electrical actuator to control the valves. Which would look like standard inlet or exhaust valves only on a much smaller scale.
Maybe such valves are already being made for r/c planes or small engines.
The actuator/control-mechanism would obviously be on top of the plug.
