schema pneumatico

[roby88]

Good morning, everyone. .
I'm here to ask you some advice on a pneumatic circuit that my partner and I should do but this time we can't find a solution. press that we can only use pneumatic valves (the customer does not want electricity).
I hope I can explain myself pretty well.
we have two cylinders double effect a and b.
pressing a p button both cylinders go out, releasing the button returns the cylinder to while b stays out. by pressing the p button, the cylinder comes out again (b is still out); releasing the button falls both.
We did a sketchy lace but I don't know how to attach it. . .
Thank you very much
Good day

http://www.valentiniweb.com/piermo/sistemi/doc/pneumatica/man-c18.pdfinteresting document, maybe you can find some point for your question.
a clarification, the button must be kept pressed and the release part the following sequence or each pressure on the button starts the following sequence?

Hello technomodel,
the button is pressed to release the cylinder a and b at the beginning of the whole sequence, then if the release to return and b stays out,
and then release it both fall.
Thank you very much for the link now I look at it for good.
