When the double acting pneumatic actuator air source pressure enters the cavity between the two pistons of the cylinder from the air port (2), the two pistons are separated and moved toward the ends of the cylinder, and the air in the air chambers at both ends is discharged through the air port (4), and the two piston racks are synchronized at the same time Drive the output shaft (gear) to rotate counterclockwise.

Conversely, when the double acting pneumatic actuator air source pressure enters the air chambers at both ends of the cylinder from the air port (4), the two pistons move toward the middle of the cylinder, and the air in the middle air cavity is discharged through the air port (2), and the two piston racks simultaneously drive the output shaft (gear) ) Rotate clockwise. (If the piston is installed in the opposite direction, the output shaft becomes reverse rotation, which is double-acting reverse DL type)
