Double-acting working principle

When the air source pressure enters the cavity between the two pistons of the cylinder from the air port, the two pistons are separated and moved toward the ends of the cylinder. The air in the air chambers at both ends is discharged through the air port, and the two piston racks simultaneously drive the output shaft (gear) Rotate counterclockwise. Conversely, when the air source pressure enters the air chambers at both ends of the cylinder from the air port, the two pistons move toward the middle of the cylinder, and the air in the middle air chamber is discharged through the air port, and the two piston racks simultaneously drive the output shaft to rotate clockwise.

Single-acting working principle

When the air source pressure enters the cavity between the two pistons of the cylinder from the air port, the two pistons are separated and moved toward the ends of the cylinder, forcing the springs at both ends to compress, and the air in the air chambers at both ends is discharged through the air ports, and the two piston racks are synchronized at the same time Drive the output shaft to rotate counterclockwise. After the air source pressure is reversed by the solenoid valve, the two pistons of the cylinder move in the middle direction under the elastic force of the spring, and the air in the middle air cavity is discharged from the air port. At the same time, the two piston racks simultaneously drive the output shaft to rotate clockwise.
