By creating vacuum in the cylinder front chamber, the stem, which is solidly connected to the piston, comes out overcoming the opposing spring force. The piston is pushed by the air at atmospheric pressure that gets into the cylinder’s rear chamber through the hollow stem. The greater the pressure differential between the front chamber under vacuum and the rear chamber at atmospheric pressure, and the larger the piston thrust force will be.…
