Tested with a pressure of 4.2Bar to the piston. We had over 40 shifts starting with a 1.2ltr canister initially charged to 8Bar. We can get more shifts by working with the pulse widths of each shift. Also the linkages were poorly designed. Also the moment arm length is to be increased to bring down the operating pressure so as to increase the number of shifts.

The entire assembly weighs a little over 4kgs.
