Spring Return (Fail CW)
Applying air pressure to Port 2 drives the pistons outward,
which compresses the springs and turns the pinion
counterclockwise as the air volume on the outside of the
pistons exhausts through Port 1.
Exhausting the air pressure from Port 2 allows stored energy
of the springs to drive pistons inward, turning the pinion
clockwise. Air volume on outside of pistons vents through
Port 1.
Operation
(as viewed from top of actuator)
Double Acting
Applying air pressure to Port 2 drives the pistons outward,
which turns the pinion counterclockwise as the air volume on
the outside of the pistons exhausts through Port 1.
Applying air pressure to Port 1 drives the pistons inward, which
turns the pinion clockwise as the air volume on the inside of
the pistons exhausts through Port 2.
Exhausting the air pressure from Port 2 allows stored energy
of the springs to drive pistons inward, turning the pinion
counterclockwise. Air volume on outside of pistons vents
through Port 1.
Spring Return (Fail CCW)
Applying air pressure to Port 2 drives the pistons outward,
which compresses the springs and turns the pinion clockwise
as the air volume on the outside of the pistons exhausts
through Port 1.
