Actuator Mechanism​

  • Double acting :

Air to port A forces the pistons outwards, causing the pinion to turncounterclockwise while the air is being exhausted from port B. Air toport B forces the pistons inwards, causing the pinion to turn clockwisewhile the air is being exhausted from port A.

Pneumatic Actuator
  • Single acting :

Air to port A forces the pistons outwards, causing the springs tocompress, the pinion turns counterclockwise while air is beingexhausted from port B. Loss of air pressure on port A, the storedenergy in the springs forces the pistons inwards. The pinion turnsclockwise while air is being exhausted from port A.
