Air to Port A forces the pistons outwards, causing the pinion to turn counterclockwise while the air is being exhausted from Port B. Air to Port B forces the pistons inwards, causing the pinion to turn clockwise while the air is being exhausted from Port A. A口進氣，壓縮空氣推動活塞向外運動，使執行器輸出軸逆時 針旋轉(0o-90o)，B口排氣。 B口進氣，壓縮空氣推動活塞向內運動，使執行器輸出軸順時 針旋轉(90o-0o)，A口排氣。 | Air to Port A forces the pistons outwards, causing the pinion to turn clockwise while the air is being exhausted from Port B.

Air to port A forces the pistons outwards, causing the springs to compress, The pinion turns counterclockwise while air is being exhausted from port B. Loss of air pressure on port A, the stored energy in the springs forces the pistons inwards. The pinion turns clockwise while air is being exhausted from port A. A口進氣,壓縮空氣克服彈簧力，推動活塞向外運動，執行器輸 出軸逆時針轉動(0°→90°)，B口排氣； 執行器失氣，活塞在彈簧力的作用下向內運動，執行器輸出軸 順時針轉動(90°→0°)，A口排氣。 | Air to port A forces the pistons outwards, causing the springs to compress, The pinion turns counterclockwise while air is being exhausted from port B.
