I'm not sure how it is possible so send air "into" a cylinder rod. It looks like the the darkest gray in the picture (gradient) is the cavity in which the rods can slide back and forth, and the lightest gray is where air can enter, but not a rod. I think air can flow freely between the light gray and dark gray sections, and the boundary simply indicates where the rod stops.
