mmmmmmmmmmmm lets asume it is atmospheric & pneumatic & we consider one side only...so it could be using the diameter ratios of
d:e to perform work1. if the wheel is rotated clockwise the right side chain
A is lowered, the right side piston plate
d2. this then forces the air a down and throught the righthand side plate check valve3. however as this air
a passes further down it closes the plate check valve @ i & stops the air from entering to the annulus side of the smaller piston4. the above seems non functional
5. if the pipe attachments
l were drawn differently and allowed higher pressure air to be admitted to the top of the smaller piston e this could work, however some of the plate check valves would also cause non functionality ............
