",Actuator," is a bit of engineering jargon that just means "mover"; it's the business end of a ,pneumatic, tool; the bit that shifts about and does some useful job for us. It might be a ,pneumatic, drill bit thumped up and down by a piston, a factory ramp that lifts things and lowers them, a mechanical arm that swings things around, or something like that.
