For future reference, that's a spring return cylinder. Air goes in, the spring compresses, the piston moves. Remove the air pressure, the spring shoots the cylinder back to its home position.

As for whether it's OK to use per the rules, I can't find anything prohibiting any type of cylinder (see R78-H) as long as it's appropriately pressure-rated and unmodified.
