Fig. 2 Pistons actuating sequence. One motion step includes three piston states, e.g., states ( a )–( c ) push the rotor one step clockwise. By actuating the pistons in the sequence of AP #1 - AP #2 - AP #3, the rotor will rotate clockwise. Likewise, by actuating the pistons in an opposite sequenc...
