Dual Piston Device with Permanent Magnets

Dual Piston Device.
I have done experiments with shieldig of repelling magnets by inserting thin plates of iron between them. When the iron is thin enough, the repelling magnets stop repelling and are not holding the shield too tight.
I have a simulation on my web site: http://fdp.nu/dualpistondevice/default.asp to see timing and placement of levers. This device will give a change to test with differrent shields and shield shapes.

Will your simulation work if you instead of using only one solid metal shield, use two or three parallel thin metallic shields with a small air gap space in between the thin metal shields?  Using layers of shields makes a more effective magnetic shield.

Your reply made me realise that I forgot to tell an important information about the simulation. I only simulated motion, not forces. I just simulated how I had to place the crank and the levers, in order to let the shield move at the right time, with the right speed. One can adjust a lot by just making a lever a bit longer or shorter.
The simulation does not include magnetic forces since I don't know how to do that. So the shield with the parallel path is certainly a shape that have to be tested.

I found a device that is based on the same principle.
See the attached clip. I hope I can get it split into seperat pictures.

Who made this device? Can you post a link?
