Hello everybody
After watching a few old test videos,
it turns out you're probably going to have more engine time on your machine
Taramop,
In practice it is not useful to push the shutter between the two pistons,
he goes there alone!
Even that it pulls a lot on the thing.
To sum up, distant piston departure,
engine time on the shutter (penetration between pistons),
engine time on the pistons in "attraction" (once the shutter in place),
Shutter extraction (critical time),
engine time on the pistons in "pushed back" (once the shutter is out).
The critical time is really very critical in the sense that one must extract the shutter when it is at the maximum of its request by the pistons.
So that the traction at the entry is weaker because the pistons are distant.
The whole trick of the concept will lie in the idea that will allow the shutter to withdraw with minimal force.
Some loose ideas,
produce a minimum mechanical stroke to remove the shutter (obvious but good)
Rather than having a passage from a vacuum to a full, use "shutters",
The section of the shutters is rectangular, they rotate on themselves,
When they rotate, they both move closer to the pistons,
but leaves a leakage opening, which can be amplified if the flaps settle on one side.
Another tip is to put the shutter in balance (springs or magnetic),
so that the retraction force is minimized.
I'm sure one of you has the right idea.
